Sinusitis is a common condition that can lead to various neurological complications due to the spread of infection to the intracranial and orbital regions. Fortunately, the availability of antibiotics has significantly improved the prognosis of sinusitis-associated intracranial complications. As a result, the overall incidence of neurological complications arising from sinusitis remains low. We present a rare case of a 13-year-old male who developed epidural empyema and orbital cellulitis as a complication of acute sinusitis. The patient initially exhibited signs and symptoms of orbital cellulitis, including eyelid swelling, erythema, and pain. Subsequently, the patient's condition worsened, with the development of fever and an intensifying headache. Imaging revealed an epidural empyema, necessitating urgent medical intervention. This case highlights the importance of early recognition and prompt management of sinusitis-related intracranial and orbital complications to prevent potentially life-threatening outcomes

Abstract Purpose To assess the radiological features and clinical outcomes of odontogenic orbital cellulitis. Method Multi-centre retrospective study of odontogenic orbital cellulitis. Primary outcomes assessed were causal organism(s), clinical signs, radiological findings, management and visual outcomes. Results Four patients with odontogenic orbital cellulitis were identified for inclusion. There was an equal proportion of men and women with a mean age of 43 years (range 25–56 years). All patients presented with an orbital compartment syndrome, with visual acuity of counting fingers (n = 1, 25%), hand movements (n = 1, 25%) and no perception of light (n = 2, 50%). The organisms implicated were Streptococcus milleri (n = 3, 75%) and Streptococcus constellatus (n = 1, 25%). MRI findings showed a subperiosteal abscess was present in all cases, which was characterised radiologically as a T1-hyperintense, T2 minimally hyperintense collection with restricted diffusion and a low apparent diffusion coefficient signal. Final visual acuity ranged from 6/6 to no light perception. One patient required an orbital exenteration due to extensive necrosis with sepsis and systemic deterioration. Conclusions Odontogenic orbital cellulitis carries a serious risk of vision loss with a propensity to present with an orbital compartment syndrome secondary to Streptococcus species. Outcomes were highly variable, with two cases progressing to blindness of which one required an orbital exenteration.

Objective This retrospective study evaluates the demographic characteristics, clinical symptoms, laboratory results, treatment approaches, and outcomes of children with complications arising from bacterial sinusitis. Methods Fifty-four pediatric inpatients with sinusitis complications admitted between September 2013 and October 2022 were included in the study. These patients were categorized into two groups: those with preseptal cellulitis (group 1) and those with orbital–intracranial complications (group 2). Results The median age of the patients was 10.8 years, and 61.1% were males. Maxillary sinusitis (n = 40.74%) was the most common type of sinus involvement. Half of the patients exhibited preseptal cellulitis. The median age of our patients with intracranial complications was 13.7 years, while the median age of patients with orbital complications was 8 years. The predominant orbital–intracranial complication was meningitis, which accounted for 41% of the cases. All patients with a subdural abscess (n = 6) presented with frontal sinusitis, while all cases of cavernous sinus thrombosis (n = 3) involved the sphenoidal sinus. Surgical intervention was undertaken in 37% of cases. Streptococcus pneumoniae was the most frequently isolated microorganism. The median duration of hospital stay was 14 days, with a total median treatment duration of 21 days. There were no fatalities, although neurological sequelae were observed in 7.4% of patients (n = 4). Conclusion Preseptal cellulitis and meningitis remain the most common complications of sinusitis in children. Adolescents with sinusitis should be monitored closely for intracranial complications. The prevalence of S. pneumoniae as the most frequently detected pathogen underscores the importance of vaccination. [ABSTRACT FROM AUTHOR]

Orbital abscesses are caused by infection within or near the orbit and show obvious signs of pain, proptosis and raised inflammatory markers. Diagnosis is based on clinical features and radiological imaging, and requires early antibiotics and often surgical drainage to save vision. Sub-Tenon's injections of triamcinolone acetonide (TA) have caused localized infections in previous reports, which have responded to therapeutic interventions. Here we report a case where a delayed presentation of an orbital abscess secondary to sub-Tenon's TA for persistent post-operative cystoid macular oedema, without obvious signs of infection, rapidly progressed to cause orbital compartment syndrome. Despite treatment, the patient lost complete vision in the affected eye. This case discusses the rare and unusual cause of abscess formation and a diagnostic dilemma. [ABSTRACT FROM AUTHOR]

Orbital abscesses are primarily seen in children as complication of ethmoid bacterial sinusitis. We report a case of invasive aspergillosis causing orbital abscess in an immunocompetent child which resolved with surgery followed by antifungal therapy. This case highlights need for histopathological, and microbiological examination, including fungal culture in such cases. [ABSTRACT FROM AUTHOR]

To report a case series of seven patients with late presentation of orbital/subperiosteal abscess following oral treatment of orbital cellulitis. A retrospective case series of all patients presented with orbital abscess following oral treatment of orbital cellulitis from two tertiary-care eye centres in Riyadh, Saudi Arabia, was conducted. Demographic profiles, risk factors, initial clinical presentation, management regimens, and final outcome were analysed. Patients presented mainly with proptosis and limitation of extraocular motility without external ophthalmic inflammatory signs. Most patients needed surgical evacuation despite the appropriate initiation of intravenous antibiotics following presentation to our hospitals. Treating orbital cellulitis with oral antibiotics may lead to delayed presentation of orbital abscess without external ophthalmic inflammatory signs. [ABSTRACT FROM AUTHOR]

Introduction: The diagnosis of ocular pathology by point-of-care ultrasound (POCUS) has been well established for entities such as retinal detachment, vitreous hemorrhage, posterior vitreous detachment, and lens dislocation.1 However, the use of ultrasound to detect other conditions such as orbital abscess and endophthalmitis in the emergency setting is rarely reported. Case Report: We present a case in which POCUS was used to confirm the suspected diagnosis of endophthalmitis and orbital abscess. This case report will review the ultrasonographic findings of orbital abscess and endophthalmitis, as well as briefly discuss the literature for the use of ultrasound for these applications. Conclusion: Point-of-care ultrasound can be used to rapidly diagnose infectious pathology of the eye and orbit, which could potentially decrease time to diagnosis and time to consultation of these visionthreatening pathologies.

ObjectiveTo report and review infantile orbital abscess caused by methicillin-resistant Staphylococcus aureus (MRSA).MethodsWe report a case of MRSA-induced infantile orbital abscess accompanied by sepsis, pneumonia, and purulent meningitis. We systematically review cases of MRSA-induced infantile orbital abscess published in PubMed, Web of Science and ScienceDirect until April 2023.ResultsWe reviewed 14 patients [our patient + 13 patients (10 papers) identified via literature searches]. There were nine boys and five girls; nine neonates and five older infants; and 8 full-term births and 1 preterm birth. The gestational age at birth was unknown for five infants. The right and left orbits were affected in 10 and 4 patients, respectively. The clinical presentation included periorbital soft-tissue edema or redness (11 patients), fever (7 patients), exophthalmos (10 patients), limited eye movement (4 patients), purulent eye secretions (2 patients), and skin abscess and convulsion (1 patient each). The source of infection was sinusitis (8 patients), vertical transmission, gingivitis, dacryocystitis, upper respiratory tract infection (1 patient each), and unknown (2 patients). MRSA was detected in blood (6 patients) or pus culture (8 patients). Vancomycin or linezolid were used for 11 patients; corticosteroids were administered to only 1 patient. Surgical drainage was performed for 13 infants (external drainage, 11 patients; endoscopic drainage, 2 patients). Two patients initially had pulmonary and intracranial infections. Except for one patient with neurological dysfunction at discharge, all other infants had no sequelae or complications.ConclusionEarly aggressive anti-infective treatment and timely drainage are essential for managing MRSA-induced infantile orbital abscess.

Bichectomy is the partial removal of the Bichat's fat pad for the aim of smoothing the facial contour. The complications of bichectomy include soft tissue infections, hematoma, facial paralysis (especially buccal branch paralysis), stenon canal injuries and related complications such as sialocele and sialoadenitis, however these are not common complications in clinical practice. Here we report a case of a 29-year-old white female with a right sided orbital abscess following bichectomy. Right sided orbital abscess and orbital cellulitis was managed with endoscopic decompression and drainage. The patient healed completely with no sequela. The frequency of major complications leading to moridity after bichectomy is rare in the literature. This is the first reported intraorbital complication of bichectomy. [ABSTRACT FROM AUTHOR]

We present a unique case of acute on chronic left frontal sinusitis with an orbital abscess in the left orbit complicated by granulomatosis with polyangiitis and a defect to the structure of the orbit, among the 87 year old patient's other health-related conditions. Urgent transfer to tertiary care, and diagnostic, surgical, and multidisciplinary management were necessary to achieve a favorable clinical outcome: the eye was left undamaged and no infection spread to the brain. This report also sets out to review the literature. [ABSTRACT FROM AUTHOR]

Orbital abscesses, though rare, represent a serious complication of sinusitis and can result in significant morbidity, including permanent vision loss and intracranial spread if not managed promptly. This systematic review aims to provide a detailed analysis of the clinical presentation, diagnostic modalities, treatment approaches, and outcomes in patients with orbital abscesses. This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A comprehensive literature search was conducted across PubMed and Scopus, yielding 19 studies involving 36 patients with orbital abscesses. Data extraction focused on study design, sample size, patient demographics (age, gender), clinical presentation, diagnostic tools, treatment modalities, and outcomes, including resolution rates, complications, and recurrence. Orbital abscesses primarily affected younger populations, with a mean patient age of nine years. The most common symptoms solicited were proptosis at 75%, periorbital swelling at 80%, and pain at 70%. The diagnostic modality used in the majority, 89%, was imaging with computed tomography. All cases were given empiric intravenous antibiotics and third-generation cephalosporins, with added metronidazole. Of all the patients, 44% had to undergo any surgical intervention, usually in cases of larger abscesses or where the optic nerve was implicated. Endoscopic sinus surgery (ESS) was the most frequently used surgical approach, with a high success rate. A total of 78% of patients achieved complete resolution, and 80% experienced improved visual acuity. However, delayed intervention led to permanent vision loss in 5.5% of cases, highlighting the importance of timely treatment. The median hospital stay ranged from one to two weeks, depending on the severity of the condition and the treatment modality. Managing an orbital abscess requires early detection and treatment to avoid complications like loss of vision and intracranial extension. Smaller, medially located abscesses can be effectively treated with conservative antibiotic therapy, while larger or complicated cases require surgical treatment., Competing Interests: Conflicts of interest: In compliance with the ICMJE uniform disclosure form, all authors declare the following: Payment/services info: All authors have declared that no financial support was received from any organization for the submitted work.

To study the clinical, microbiological profile and management outcomes of orbital abscess at a tertiary care center in South India. In a retrospective interventional case series, we reviewed all patients diagnosed with orbital cellulitis from 2000–2020. The data analyzed included demographic profile, clinical and radiological features, microbiological profile, and management outcome. A total of 921 cases of orbital and periorbital infections were reviewed. Seventy-two cases were diagnosed as orbital cellulitis. Thirty-four cases (47.22%) had radiological evidence of orbital abscess. The median age was 20.63 years. Three patients (8.82%) were neonates. A male preponderance was noted (23, 67.65%). Sinusitis (10, 29.41%) and diabetes (5, 14.7%), were the most common predisposing factors. Optic neuropathy was seen in 15 (44.11%) patients, cavernous sinus thrombosis in two patients (5.88%), and septicemia in one patient (2.94%) Multiple orbital abscesses were noted in 7 (20.59%) cases. All patients underwent surgical drainage. Methicillin-sensitive Staphylococcus aureus was the most common organism isolated in 14 patients (41.18%). Vision improvement or stabilization was seen in all except 3 (8.82%) Orbital abscess is a potential sight-threatening orbital infection. The infective process can spread and ascend up to involve cavernous sinus thereby becoming life-threatening. A timely diagnosis and intervention can halt the disease process and help restore vision in many cases. [ABSTRACT FROM AUTHOR]

Background: Orbital, intracranial, and osseous extra-sinus complications can arise from bacterial or fungal sinusitis. Odontogenic sinusitis (ODS) can cause extra-sinus complications, but its prevalence remains poorly characterized. Objective: To determine the frequency of ODS as a cause of operative extra-sinus infectious complications and describe clinical features of all complicated sinusitis cases. Methods: A multi-institutional retrospective review was performed on all operative sinusitis-related extra-sinus complications from 2011 to 2020. ODS was diagnosed by sinus computed tomography (CT) and dental evaluations when available. Demographics, complication types, sinusitis etiologies, and various clinical features were analyzed. Results: Forty-five patients were included (mean age 55.5 years, 56% male). Of the extra-sinus complications, 40% were orbital only, 22% intracranial only, 13% osseous only, and 25% involved combined complications. The 2 most common causes of extra-sinus complications were ODS (40%) and mucopyocele (27%). When invasive fungal etiologies were excluded, and only unilateral maxillary opacification on CT was considered, nearly 60% of extra-sinus complications were due to ODS. Unilateral maxillary sinus opacification on CT was present in 100% of complicated ODS compared to 44% of nonodontogenic cases, and oral anaerobes were only identified in ODS cases. No complicated ODS patients underwent dental interventions during hospitalization. Conclusion: ODS was the most common cause of operative extra-sinus infectious complications. Clinicians should consider ODS high on the differential diagnosis of all patients presenting with complicated sinusitis, especially when sinusitis is unilateral and invasive fungal infection is not suspected.

Periorbital infections lead to severe condition of the orbital abscess, and eventually to sight loss, and even death. Current study aims in reviewing the literature regarding orbital abscess in adult patients and presenting 2 original cases. A surgical intervention to drain the abscess and a revision of the orbital was required. A review of literature is also reported focusing on aetiology and treatment options dealing with an orbital abscess. [ABSTRACT FROM AUTHOR]

A 28-year-old male presented with gradually progressive swelling of the right lower eyelid along with a prominence of the eye for 6 months. He had received oral steroids and intraorbital triamcinolone acetonide injection in the inferior quadrant for active thyroid eye disease. External examination revealed right eye proptosis and swelling along the inferior orbital region. Magnetic resonance imaging showed an ill-defined soft tissue lesion in the inferior extraconal space and a bulky right inferior rectus. Histopathology of the biopsied material revealed inflammation with septate fungal filaments, identified as Aspergillus flavus on culture. He responded well to oral voriconazole despite a recurrence during the course of treatment. Intraorbital steroids are given for idiopathic and thyroid-associated orbital inflammation. This is a report of a rare complication of fungal orbital abscess following intraorbital corticosteroid injection in an immunocompetent young patient. [ABSTRACT FROM AUTHOR]

Complications of acute rhinosinusitis(ARS) in the pediatric population can include intra- and extracranial involvement from spread of infection. Though these infections are most commonly preceded by a URI, infection with Sars-CoV-2 (COVID-19) as the inciting event for complicated ARS has rarely been described in the pediatric population. Furthermore, decision making surrounding surgical management of acutely infected patients with COVID-19 remains complicated. This case demonstrates complicated ARS in an otherwise healthy 10-year-old patient with an orbital abscess following COVID-19 infection, ultimately requiring both internal and external surgical approaches for adequate management.

Abstract A 44‐year‐old male Japanese was admitted for further post‐remission treatments for acute myeloid leukemia. He developed a right orbital abscess. An isolate of Lomentospora prolificans was obtained from the lesion, and orbital biopsy also revealed the presence of Aspergillus fumigatus. This fatal case involved a concurrent dual fungal infection.

Orbital abscesses are most commonly associated with co-existing active paranasal sinus infection. Herein, the authors present the case of an orbital abscess in the setting of costal tubercular osteomyelitis and an anterior chest wall abscess in the absence of any paranasal sinus pathology in an immunocompetent patient. Costal tuberculosis is a very rare form of extrapulmonary skeletal tuberculosis and is challenging to diagnose. Initial presentation as an orbital abscess remote from the site of the primary pathology is of extremely rare occurrence. In this instance, the diagnosis of tuberculous osteomyelitis was suspected primarily on the basis of clinicoradiological features. The patient was treated with, and responded well to, standard first-line anti-tubercular therapy (ATT) for extrapulmonary tuberculosis. [ABSTRACT FROM AUTHOR]

Abstract Background Subtenon injection of triamcinolone acetonide (STTA) has been widely adopted in the clinical setting of ophthalmology and its infectious complications are rare. However, orbital abscess following STTA has been reported in seven cases. Furthermore, although eye infections due to Exophiala species are uncommon, there have been 19 cases to date. E. jeanselmei, E. phaeomuriformis, E. werneckii, and E. dermatitidis have been reported to cause human eye infections; however, to the best of our knowledge, orbital abscess caused by E. dermatitidis has not yet been reported. We describe the first documented case of fungal orbital abscess caused by E. dermatitidis following STTA. We also review the related literature of orbital abscess following STTA, as well as eye infections caused by the four Exophiala species. Case presentation The patient was a 69-year-old Japanese woman with diabetic mellitus. She had a macular oedema in her right eye, which occurred secondary to branch retinal vein occlusion. An orbital abscess caused by E. dermatitidis occurred 4 months after the second STTA for the macular oedema, which was successfully treated by a surgical debridement and systemic administration of voriconazole. Conclusions Our findings in the patient and from our literature survey caution ophthalmologists to the fact that STTA can cause fungal orbital infections, especially in diabetic patients. Furthermore, surgical treatment is one of the most important risk factors.

Abstract Background Complications of acute sinusitis affecting multiple sites are very uncommon, and generally develop for a delayed diagnosis of the primary infection, with possible severe and life-threatening evolution. Patients can have variable presentations according to the site and extent of the infection. Multiple forms generally include the coexistence of orbital manifestations and intracranial infections. We here present a case with unusual multiple sites locations (i.e.: intraorbital intraconic abscess, sigmoid sinus thrombosis, preclival abscess, multiple splanchnocranium osteomyelitic processes). Case presentation A 13-year-old male presented at our hospital with right progressive orbital oedema with eyesight worsening and signs of meningitis. Computed tomography and magnetic resonance (MRI) demonstrated right intraorbital intraconic abscess, left sphenoidal sinusitis, transverse and sigmoid sinus thrombosis. Ophthalmologic evaluation documented a right optic nerve sufferance. Endoscopic and superior right trans-palpebral surgical decompression was performed, and the abscess was drained. Microbiological analysis revealed the presence of multi-sensitive Streptococcus Intermedius. Subsequent prolonged antibiotic and anti-thrombotic treatments were started. In the following two-weeks the sinusal and ophthalmologic clinical conditions improved, whereas the patients complained of mild to moderate cervical pain and suffered from intermittent pyrexia. Control MRI documented clival abscess extending up to preclival soft tissues posterior to the nasopharynx, associated with mandible osteomyelitis, occipital condyles and anterior part of the temporal bone hyper intensity. Endoscopic trans-nasal surgical approach to the clival compartment with neurosurgery navigation-guided achieved preclival abscess drainage. Complete clinical and radiological recovery was achieved after 45 days of medical treatment. Conclusions Multiple sites complicated rhinosinusitis is uncommon, and its management is challenging. A proper history and thorough clinical examination along with a radiological evaluation are key factors in the final diagnosis of patients with complicated multiple sites acute rhinosinusitis. A quick multidisciplinary approach is always necessary to avoid unwanted life-threatening complications.

Odontogenic sinusitis (ODS) is a common cause of orbital, intracranial, and osseous infectious extrasinus complications. Dental infections can spread to the orbital or intracranial spaces though the sinuses via thrombophlebitis or direct extension, or from the dentition or oral cavity via vascular channels in the maxillary alveolar bone. ODS typically presents with unilateral involvement both clinically and radiographically. Any suspicion for extrasinus spread based on history and physical examination should be followed by appropriate imaging, formal dental evaluation, and, when appropriate, ophthalmology and neurosurgery consultations. This multidisciplinary approach ensures appropriate management of both the acute orbital and intracranial complications., Competing Interests: Disclosure The authors have no conflicts of interest to disclose., (Copyright © 2024 Elsevier Inc.

Orbital abscesses secondary to odontogenic infections are rare but can lead to serious complications, including compressive optic neuropathy and permanent vision loss, if not diagnosed and treated promptly. We present the case of a 13-year-old child with a radiologically confirmed orbital abscess associated with a recent odontogenic infection. The patient initially presented with a one-week history of right eyelid swelling and fever. The symptoms began after treatment for dental caries, during which the patient was prescribed a three-day course of oral antibiotics. Despite emergency pulp extirpation, the swelling worsened, leading to severe proptosis, decreased vision, and mild optic nerve dysfunction. Surgical exploration of the right orbit with incision and drainage revealed 8 mL of thick purulent material. Culture results confirmed Streptococcus intermedius as the causative organism. Following a combination of intravenous antibiotics and surgical intervention, the patient showed significant improvement, with resolution of swelling and restoration of vision. This case highlights the critical importance of early diagnosis, timely imaging, and surgical and medical management integration in preventing vision-threatening complications of orbital abscesses caused by odontogenic infections in pediatric patients., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Medical myths develop when existing beliefs are not challenged. They remind us that we can be mistaken and need to question ourselves. Oculoplasty, a vital branch of ophthalmology, has been of interest to surgeons since olden days. This field has seen transformative changes in the last few years in light of new understanding and sophisticated techniques. In this write-up, we wish to address a dozen of these “unchallenged” myths which may not be wrong concepts but conventional approaches that need renewed thinking.

Introduction: Considering the little evidence regarding peri-orbital infections, this study was aimed to obtain information about the epidemiology, etiology, and management of orbital infections. Material and Methods: In this retrospective investigation, all patients with peri-orbital infection who were hospitalized in a tertiary ophthalmologic center in AL-Zahra hospital, Isfahan, Iran from 2008 up to 2018 were identified. Documented data and radiographic images were extracted. The data regarding epidemiology, etiology and disease course was analyzed. Results: Sixty nine patients (35 males, 34 females) with the age range between 3 months to 85 years were included. Preseptal cellulitis was recorded in 53 cases (76.8%) and orbital cellulitis was seen in 16 cases (23.2%), and the proportion of preseptal to orbital was 3.3 to 1. The mean duration of hospitalization in patients with preseptal cellulitis was 6.38 ±, 4.59 days and in patients with orbital cellulitis was 12.44 ±, 9.63 days. Most patients with preseptal cellulitis were treated by medication therapy (71.7%), while the orbital cellulitis were often treated by surgical procedures (56.2%). Sinusitis was the main cause of both preseptal and orbital cellulitis in all age groups, except infants under 1 year, which dacryocystitis was identified as primary factor. Conclusions: The prevalence of peri-orbital infection was higher in children. The prevalence ratio of preseptal to orbital cellulitis was 3.3:1. The main etiologic factor was sinusitis. There is no agreement for the treatment modalities of peri-orbital infections and the timing of surgical intervention. Continuous evaluation of treatment course, both clinically and radiographically is important. Reassessment is recommended when improvement is not seen after 6-7 days of treatment.

Introduction: We report a rare case of pan sinusitis with orbital cellulitis in a 3-year-old male child. Orbital cellulitis is considered as an ocular emergency which needs urgent evaluation and proper quick action to save the patient vision or even life. It can affect both adults and children but has a greater tendency to occur in the pediatric age group. Methods: A 3-year-old male child presented to us with history of fever since 15 days. Later he developed swelling of left eye lid since 8 days. His visual acquity was fixating and following light. On anterior segment examination there was diffuse upperlid edema of left eye associated with mild erythema and matting of lashes. On MRI, it shows left sided pansinusitis with orbital cellulitis. Results: In view of left sided pansinusitis with orbital cellulitis, Functional Endoscopic Sinus Surgery with orbital decompression was done. Pus from the middle meatus was taken, sent for culture and sensitivity and the organism isolated was methicillin resistant Staphylococcus aureus (MRSA) positive growth and child was continued on antibiotics i.e., Teicoplanin and Metrogyl. Patient showed marked improvement in both ocular and general condition. Conclusion: Currently, imaging studies for detection of orbital abscess, the use of antibiotics and early drainage have mitigated visual morbidity significantly. The purpose of this review is to describe current investigative strategies and management options in the treatment of orbital cellulitis, establish their effectiveness and possible complications due to late intervention. This case report will be of interest particularly to the ophthalmologists, the otorhinolaryngologists, and the paediatricians.

Background: Rebamipide ophthalmic suspension was launched in Japan in 2012 and is used for the treatment of dry eye.Case Presentation: We report two cases of orbital abscess, which resulted from dacryocystitis that occurred after administration of rebamipide ophthalmic suspension. Computed tomography images showed an eyeball deformity in one case and exophthalmos in the other. In both cases, light microscopy, scanning electron microscopy and energy dispersive X-ray examinations revealed lacrimal sac concretions, which contained calcium phosphate crystals that were surrounded by microorganisms. Lacrimal sac concretion removal from the lacrimal sacs during dacryocystorhinostomies was performed on both patients. Although the postoperative outcome was favorable in one case, vision was lost in the other case due to the development of retinal artery occlusion as a complication of the orbital abscess, despite lacrimal sac concretion removal and administration of antimicrobials.Conclusions: This is the first case report to highlight that rebamipide ophthalmic suspension can cause an orbital abscess via development of lacrimal sac concretion. Ophthalmologists should be aware that rebamipide ophthalmic suspension might induce the formation of concretion in the lacrimal sac.

Purpose: The role of adjuvant systemic corticosteroids in the management of periorbital cellulitis and subperiosteal/orbital abscesses secondary to sinonasal infections is not well understood. Our objective was to systematically review the current evidence on the efficacy and side effects of systemic steroids when used in the management of periorbital cellulitis. Methodology: A systematic review of literature was conducted in accordance with PRISMA guidance. A systematic search of MEDLINE, Embase and Cochrane databases, MetaRegister and ISI conference proceedings was conducted. The outcomes of interest were duration of inpatient stay, requirement for surgical intervention, adverse effects and recurrent/residual symptoms. Results: Four studies were identified involving 118 patients. Of these, 78 underwent treatment with systemic corticosteroids and 40 were controls. Meta-analysis demonstrated that the mean duration of inpatient stay was significantly shorter in the steroid group (WMD − 2.90 days; 95% CI − 3.07, − 2.73; p < 0.00001). There were no significant differences in requirement for surgical intervention (RR 0.93; 95% CI 0.50, 1.75; p = 0.83). Side effects were reported in 6/78 patients (7.7%), with 5 patients showing signs of hyperactivity and 1 patient with insomnia. These were mild except in one case, which required early cessation of corticosteroids. There was one case of recurrence of symptoms in each cohort (steroid vs. non-steroid) following discharge. Conclusions: The evidence suggests that systemic corticosteroids may offer some benefit in the management of periorbital cellulitis secondary to sinonasal infections. However, there is significant heterogeneity and risk of bias. A well-designed randomised controlled trial may provide a better insight into the efficacy of systemic steroids for this condition.

Pyomyositis is a rare condition which occurs most often in large skeletal muscles. Pyomyositis of extraocular muscles is a very rare entity. The authors describe a case of 2 sites of pyomyositis of extraocular muscles. A 20-year-old man presented with right periocular pain, redness, and proptosis for 1 week.Computed tomography showed well-circumscribed masses with enhancing rims in the medial and inferior rectus muscles. The patient underwent orbital drainage surgery and received an intravenous antibiotic. Haemoculture and pus culture could not identify an organism. Systemic steroid was administered after the infection was controlled, in regard to scar prevention. [ABSTRACT FROM AUTHOR]

Introduction Orbital cellulitis is an infectious condition that presents a gap in the literature in regard to its manifestations in the Middle East. A retrospective investigation was undertaken at one tertiary care facility in Kuwait, aiming to augment regional insights into the etiological factors and subsequent outcomes associated with this condition. Methods A retrospective review collected data from 92 patients in a tertiary care center in Kuwait for patients admitted with pre-septal and orbital cellulitis between January 2013 and June 2023. Primary outcomes assessed the resolution of symptoms, categorized as "completely resolved" and "resolved with complications". Secondary outcome measures included patients' ages, microbiology, laboratory, and radiological findings. Gender, predisposing conditions, surgical status, and orbital involvement were additionally extracted and analyzed descriptively. Results Data of n=92 (56 males and 36 females) were extracted. Ages ranged from 20 days to 18 years, the mean being seven years. Additionally, 52.2% (n=48) were diagnosed with orbital cellulitis, and 42.4% (n=39) were diagnosed with pre-septal cellulitis on admission. Cultures were available for n=60. Specifically, 52.1% (n=48) received CT scans; 6.5% (n=6) MRI scans; and 98.9% (n=91) received antibiotics (microbiology investigated: n=83). Ceftriaxone was used in 82.6% (n=76); 20.6% (n=19) received surgical interventions, and incision and drainage (I&D) were done on 15.2% (n=14). Visual acuity was assessed in 59.7% (n=55) patients. Five (5.43%) reported visual deterioration, and 87 (94.6%) of the outcomes were classified as "completely resolved". Conclusion Upper respiratory tract infections were the most common documented predisposing risk factor in the development of pre-septal and orbital cellulitis. Adverse outcomes in vision were documented in 5.43% of patients. A paucity of regional data highlights the importance of conducting further studies locally., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study. Al-Bahar Ethics Committee issued approval 001-10-22.

Background: Intracranial and orbital abscesses in combination together are rare complications of sinusitis. They can be life-threatening and can result in multiple sequelae. Case presentation: A 9-year-old female presented with left periorbital swelling, gaze restriction and headache. Following scans, she underwent emergency endoscopic sinus surgery, evacuation of the intraorbital empyema and stereotactic mini-craniectomy with the evacuation of the extradural empyema as a joint case. The patient recovered well and was discharged to complete intravenous antibiotics for 6 weeks. Conclusion: In the pediatric population intracranial complications of acute sinusitis can have more devastating consequences. Therefore prompt recognition and management are essential within a multidisciplinary team setting. We also highlight the rarity of concomitant multi-site abscess formation and the need to be vigilant for same.

Orbital compartment syndrome (OCS) is described in humans as an acute rise in intraorbital pressure following a severe and rapidly evolving orbital affection. It includes orbital oedema, haemorrhage or infection causing a marked reduction in local blood perfusion, and severely affecting the orbital neurovascular structures. If not promptly recognised and treated, it results in irreversible blindness. It is one of the rare ophthalmic surgical emergencies, requiring lateral canthotomy and cantholysis. This case report describes two canine cases of complex orbital, periorbital and facial abscesses resulting in OCS and permanent unilateral blindness diagnosed by ultrasonography, computed tomography and electroretinography.

Introduction: Complication of an odontogenic infection to an orbital abscess is not a common presentation. The progression from a simple toothache to a condition that may lead to loss of vision is sudden and severe. Case Report: We report a rare case in which a patient developed facial cellulitis that progressed to orbital abscess after unsterile dental manipulation by a medical fraudster (“quack”). The patient was initiated on high-grade antibiotics, which resolved the facial cellulitis. However, the patient developed orbital abscess with restricted mobility of the right eye in the lateral gaze. After radiological confirmation of the abscess, it was drained by an external approach. Due to timely intervention, the extra-ocular mobility was regained, and the vision remained unaffected. Conclusion: Knowledge of the routes of the spread of dental infection to the vital structures and the urgent need for aggressive multidisciplinary management is paramount. Furthermore, awareness of the rising quack culture in developing nations needs to be increased.

A 44‐year‐old male Japanese was admitted for further post‐remission treatments for acute myeloid leukemia. He developed a right orbital abscess. An isolate of Lomentospora prolificans was obtained from the lesion, and orbital biopsy also revealed the presence of Aspergillus fumigatus. This fatal case involved a concurrent dual fungal infection. [ABSTRACT FROM AUTHOR]

Aim: To identify the predictors of poor outcome and need for surgical management in paediatric patients with periorbital cellulitis. To assess the adherence to local guidelines in the management of periorbital cellulitis.Methods: Retrospective descriptive analysis of clinical, laboratory and radiological characteristics of 175 paediatric periorbital cellulitis presentations at a UK teaching hospital over a 10-year period. Regression investigated correlations for continuous and categorical variables.Results: A total of 175 paediatric presentations were diagnosed as periorbital infections over the 10-year period. Of these, 139 had pre-septal cellulitis, 27 had a subperiosteal abscess, 6 had an orbital cellulitis, 1 had an orbital abscess, 1 a cavernous sinus thrombosis and 1 an extradural abscess. Median age at presentation was 5 years (range: 1 month-17 years). In total, 169 (97%) cases received systemic antimicrobial treatment. Cross-sectional imaging occurred in 30% of cases and 18% required surgical intervention. Increasing C-reactive protein was associated with greater risk of post-septal disease and requiring surgery. The best predictors of post-septal disease in the multivariate analysis (R2 = 0.49, P = ≤0.001) were ophthalmoplegia (P = 0.009), proptosis (P = 0.016) and pain on eye movement (P = 0.046). Proptosis was the single most significant predictor of surgical management (R2 = 0.53, P = <0.001).Conclusion: Multidisciplinary involvement and early medical management can improve outcomes for most patients. Those who deteriorate despite medical management should be considered for prompt imaging and surgical management to avoid serious life-threatening or sight-threatening complications.

• COVID-19 can affect the presence of bacteria within certain anatomical regions. • Peptoniphilus indolicus is usually found in the vagina or gut biome, but it can be found in the sinonasal cavity in a COVID patient as well. • The sinonasal cavity can become avascular as a result of COVID infections. • Although rare, orbital abscesses can drain spontaneously or require enucleation. Peptoniphilus indolicus is not usually seen in the eye or paranasal sinuses but is a commensal of the human vagina and gut. However, with COVID-19, eye infections and other unusual complications are possible with such unsuspected bacteria. The patient is a 76-year-old white male from a nursing home tested positive for COVID-19 and was sent from a nursing facility for left eye drainage and psychiatric evaluation. Upon presentation, the patient was not fully oriented and could not provide a history of the eye drainage. CT scan showed sinusitis with left orbital and periorbital abscess formation, cellulitis, and extensive osteomyelitis. He underwent endoscopic transnasal drainage and orbiotomy. Cultures returned positive for methicillin-resistant Stapholococcus aureus (MRSA), Streptococcus constellatus, and Peptoniphilus indolicus. He was maintained on several days of IV antibiotics and returned to the nursing home. He then presented 2 months later and required enucleation of his globe, due to the presence of multiple scleral perforations in the setting of orbital abscess, as well as removal of necrotic orbital bone. Given the concomitant infection with COVID-19 and unusual presentation, the patient's sinus cultures support the notion that COVID-19 can affect the presence of bacteria within certain anatomical regions. Specifically, Peptoniphilus indolicus is not normally found outside of the vagina or gut biome. Avascular, pale mucosa and bone of the nasal cavity was noted during surgery of this COVID-19 infected patient, which is in contrast to the friable and edematous tissue typically found in acutely infected sinuses. Our patient's orbital abscess began to drain spontaneously through the skin, which is rare for orbital abscesses. Also uncommon with orbital abscesses is the need for enucleation, which in this case was deemed necessary given that the abscess had perforated the sclera in multiple locations.

Background: Subtenon injection of triamcinolone acetonide (STTA) has been widely adopted in the clinical setting of ophthalmology and its infectious complications are rare. However, orbital abscess following STTA has been reported in seven cases. Furthermore, although eye infections due to Exophiala species are uncommon, there have been 19 cases to date. E. jeanselmei, E. phaeomuriformis, E. werneckii, and E. dermatitidis have been reported to cause human eye infections; however, to the best of our knowledge, orbital abscess caused by E. dermatitidis has not yet been reported. We describe the first documented case of fungal orbital abscess caused by E. dermatitidis following STTA. We also review the related literature of orbital abscess following STTA, as well as eye infections caused by the four Exophiala species.Case Presentation: The patient was a 69-year-old Japanese woman with diabetic mellitus. She had a macular oedema in her right eye, which occurred secondary to branch retinal vein occlusion. An orbital abscess caused by E. dermatitidis occurred 4 months after the second STTA for the macular oedema, which was successfully treated by a surgical debridement and systemic administration of voriconazole.Conclusions: Our findings in the patient and from our literature survey caution ophthalmologists to the fact that STTA can cause fungal orbital infections, especially in diabetic patients. Furthermore, surgical treatment is one of the most important risk factors. [ABSTRACT FROM AUTHOR]

Background: Complications of acute sinusitis affecting multiple sites are very uncommon, and generally develop for a delayed diagnosis of the primary infection, with possible severe and life-threatening evolution. Patients can have variable presentations according to the site and extent of the infection. Multiple forms generally include the coexistence of orbital manifestations and intracranial infections. We here present a case with unusual multiple sites locations (i.e.: intraorbital intraconic abscess, sigmoid sinus thrombosis, preclival abscess, multiple splanchnocranium osteomyelitic processes). Case presentation: A 13-year-old male presented at our hospital with right progressive orbital oedema with eyesight worsening and signs of meningitis. Computed tomography and magnetic resonance (MRI) demonstrated right intraorbital intraconic abscess, left sphenoidal sinusitis, transverse and sigmoid sinus thrombosis. Ophthalmologic evaluation documented a right optic nerve sufferance. Endoscopic and superior right trans-palpebral surgical decompression was performed, and the abscess was drained. Microbiological analysis revealed the presence of multi-sensitive Streptococcus Intermedius. Subsequent prolonged antibiotic and anti-thrombotic treatments were started. In the following two-weeks the sinusal and ophthalmologic clinical conditions improved, whereas the patients complained of mild to moderate cervical pain and suffered from intermittent pyrexia. Control MRI documented clival abscess extending up to preclival soft tissues posterior to the nasopharynx, associated with mandible osteomyelitis, occipital condyles and anterior part of the temporal bone hyper intensity. Endoscopic trans-nasal surgical approach to the clival compartment with neurosurgery navigation-guided achieved preclival abscess drainage. Complete clinical and radiological recovery was achieved after 45 days of medical treatment. Conclusions: Multiple sites complicated rhinosinusitis is uncommon, and its management is challenging. A proper history and thorough clinical examination along with a radiological evaluation are key factors in the final diagnosis of patients with complicated multiple sites acute rhinosinusitis. A quick multidisciplinary approach is always necessary to avoid unwanted life-threatening complications. [ABSTRACT FROM AUTHOR]

Introduction: Limited data is available on paediatric orbital cellulitis in Asia. We aimed to describe demographic data, clinical presentation, predisposing factors, identified microorganisms, choice of antibiotics and management in children with orbital cellulitis treated in a tertiary care centre in Malaysia.Methods: A retrospective review was performed on children with orbital cellulitis aged below 18 years who were admitted to Hospital Universiti Sains Malaysia, Kelantan, Malaysia, between January 2013 and December 2017.Results: A total of 14 paediatric patients fulfilling the diagnostic criteria for orbital cellulitis were included. Their mean age was 6.5 ± 1.2 years. Boys were more likely to have orbital cellulitis than girls (71.4% vs. 28.6%). Involvement of both eyes was observed in 14.3% of the patients. Sinusitis (28.6%) and upper respiratory tract infection (21.4%) were the most common predisposing causes. Staphylococcus aureus (28.6%) was the leading pathogen. Longer duration of hospitalisation was observed in those infected with methicillin-resistant Staphylococcus aureus and Burkholderia pseudomallei. 10 (71.4%) patients were treated with a combination of two or three antibiotics. In this series, 42.9% had surgical interventions.Conclusion: Young boys were found to be more commonly affected by orbital cellulitis than young girls. Staphylococcus aureus was the most common isolated microorganism. Methicillin-resistant Staphylococcus aureus and Burkholderia pseudomallei caused severe infection. Sinusitis and upper respiratory tract infection were the most common predisposing factors. A majority of the children improved with medical treatment alone. Our findings are in slight disagreement with other published reports on paediatric orbital cellulitis, especially from the Asian region. [ABSTRACT FROM AUTHOR]

Background: Orbital abscess is a very rare occurrence in early infancy. Case characteristics: A 40 days old infant brought with fever and sudden onset proptosis with eye lid erythema and edema of the left eye. Outcome: The infant required emergent drainage of abscess and multiple concomitant procedures to drain out pus completely. He got better with appropriate antibiotics and surgical intervention. Message: Orbital abscess in some babies may need aggressive repeated surgical intervention along with appropriate antibiotics.

The aim of the study is to determine epidemiological profile of cases admitted with suspicion of pre or post septal cellulitis and to define and evaluate the various factors associated with the aetiology, presentation, diagnosis and management of orbital and preseptal cellulitis via a one year study of ten cases presenting to a tertiary care hospital in western Rajasthan, India. All patients presenting to our department or being transferred from other departments to us with the diagnosis of pre/post septal cellulitis from the March of 2017 to February 2018 were considered for this case series. Data compilation of these patients was done which included age, sex, chief complain, duration of illness, associated co-morbidities, time of presentation, management plan undertaken and associated radiological findings. All these aspects were then evaluated. Our study included 10 cases. Of these 8 were less than 14 years and 2 were over 50 years. Both the adults were female and were positive for Diabetes Mellitus type two. 80% of these patients presented between the duration of November to February with maximum (40%) in the month of December. In 7 of these 10 patients, the cellulitis was associated with underlying sinusitis. Six patients were admitted directly from ENT OPD while other 4 were being managed in other ward before being transferred to us. All patients were managed conservatively except 1 who required surgical intervention. Pre/post septal cellulitis is a dangerous condition in which prompt intervention needs to be undertaken as it can be difficult to predict what course it will follow. Radiological evaluation should be done in all cases as most cases are associated with an underlying sinus infection. Also, it is more common in paediatric age group and the patient may initially be referred to an ophthalmologist or a paediatrician in which case it becomes very important that a good working interdepartmental collaboration be present so that correct management plan can be followed.

Subperiosteal abscess is a condition that typically presents as collection of pus in the space between the periorbital and the lamina papyracea as a result of the migration and spread of an infection, such as sinusitis and ethmoiditis. The low incidence requires a high index of suspicion to be considered in the differential diagnosis when encountering this life-threatening illness. This case highlights the significance of a prompt and accurate diagnosis for this infrequent condition, because it may progress to blindness, meningitis, intracranial abscess, and death. We present evidence to address the controversies of two approaches, immediate surgical drainage of the abscess versus more conservative pharmacologic medical treatment. [ABSTRACT FROM AUTHOR]

Orbital cellulitis is an infection of the orbital soft tissues posterior to the orbital septum. It has the potential to be affect sight and function of the eye and extraocular tissues. Although it is commonly seen in the pediatric age group, adult orbital cellulitis is not uncommon. Infection usually originates from sinuses but sometimes the nidus of infection is in the eyelids, from retained vegetative foreign bodies, or very rarely from distant infection spreading to the orbit spread from blood. It is characterized by pain, proptosis, chemosis, diminution of vision, fever, periorbital erythema, and limitation of ocular motility. Historically orbital cellulitis was a sight and life-threatening condition. However, with the advent of high quality imaging, antibiotics and early surgical intervention to drain the orbital abscess when indicated, the chances of visual loss have reduced significantly. The purpose of this review is to describe current investigative and management paradigms in the treatment of orbital cellulitis and current recommendation in the management of complications resulting from it.

Odontogenic infections are common and very often spread to potential spaces of head and neck. The spread of such infection to adjacent maxillary sinuses or distant sites such as the orbits are a rare occurrence and may develop periorbital and orbital cellulitis. Unfortunately once orbital cellulitis and subsequently orbital abscess develops it can give rise to serious complications such as complete blindness or even more serious and life-threatening situations as cavernous sinus thrombosis, intracranial abscess or even death. Two cases are presented to demonstrate the differences between the two conditions and the necessary management in either case. This article provides an insight into the clinical behaviour of orbital infections of odontogenic origin with contemporary diagnostic and treatment modalities that will help in reducing morbidity and mortality associated with these conditions.

Purpose: We describe this case and review the literature, to allow this to be a cautionary tale in the interpretation of fluid collections in the setting of spontaneous globe subluxations (GS). Observations: A 58 year old female, with a past medical history of globe subluxation, was diagnosed radiographically with an orbital abscess, and managed with an orbitotomy. However, no abscess was identified operatively and subsequent imaging showed only extravasation of serous fluid. Conclusions and importance: We postulate that in the case here, the fluid collection posterior to the globe was in fact due to increase venous congestion and decrease venous return posteriorly from the globe to the cone, leading to an efflux of clear serous fluid. We postulate that in the case of GS without other clinical indications suggesting orbital abscess one can consider a posterior globe collection of fluid to be an extravasation of serous fluid, secondary to increased venous congestion.

Purpose: This is a case report of an unusual case of the family transmission of Streptococcus pyogenes infection in three siblings. One brother contracted the infection which resulted in orbital cellulitis of two of his siblings, in the absence of anatomical or immunological predisposing factors. Observations: A young boy contracted an uncomplicated S pyogenes upper respiratory tract infection. The twin brother closely followed by the older sister both developed a S pyogenes orbital cellulitis a couple of days later. Conclusions and importance: To our knowledge, this is the first case ever reported of family transmission of orbital cellulitis. This highlights the importance of early diagnosis and treatment of S pyogenes, and the role of throat cultures as means of diagnosis even in the absence of symptoms or signs of pharyngitis.

Efforts aimed at minimizing the spread of COVID-19 and "flattening the curve" may be affecting clinical care delivery for non-COVID-19 cases that include otolaryngologic and orbital conditions. We are witnessing changes in the manner that patients present, as well as modifications in clinical management strategies. An improved understanding of these phenomena and the contributing factors is essential for otolaryngologists to provide sound clinical care during this unprecedented pandemic. [ABSTRACT FROM AUTHOR]

Background: Orbital abscess formation is one of the uncommon complications that occur following facial trauma. We report a rare presentation of orbital abscess in a young adult with post closed facial fracture. Materials and Methods: a case report. Result: A 19-year old man who sustained head injury and facial bones fractures without any external adnexal wounds from a road traffic accident. He developed left periorbital haematoma and decrease vision after 3 days of trauma. He was suspected to have left optic neuropathy and empirically treated with corticosteroids. However, his left vision deteriorated and developed progressive proptosis within 3 days. Serial CT scan showed new formation of left subperiosteal and intraconal abscess. Endoscopic orbital decompression and drainage of the abscess was performed. Post operatively, his vision and the proptosis improved. Orbital abscess post closed facial fracture is an unusual complication. Conclusion: High index of suspicion is necessary to diagnose this unusual presentation. Prompt treatment is essential to save the vision. [ABSTRACT FROM AUTHOR]

Background: Orbital infection related to mandibular third molar infection is extremely rare. Most of cases reported in literature are related to maxillary molar teeth. Odontogenic infections are not common causes of orbital abscess but it should always be put in consideration when dealing with orbital cellulitis and abscess.Case presentation: This is a case of orbital abscess involving the left eye as consequence of lower left third molar infection in otherwise healthy 35-year-old black male patient. CT scan confirmed the unusual pathway of this space infection from the lower third molar and excluded any intracranial involvement. The abscess was drained immediately by intraoral incisions and the tooth was extracted. There was a dramatic improvement in a very short time with normal eye movement.Conclusion: This case demonstrates one of the serious consequences of odontogenic infection which may lead to cavernous sinus thrombosis and blindness if not treated promptly.
