An endoscope is a useful adjunct for the retinal surgeon to overcome haze of a compromised anterior segment. It allows early surgery in trauma and infections which translates to better results. Intraocular glass foreign body is a challenging condition, demanding highly skilled surgical expertise. We present endoscopic removal of an intraocular foreign glass body in a badly traumatised and infected eye. The surgical challenge was accentuated by an imaging misdiagnosis of ‘twin metallic foreign bodies’.

Introduction: Corneal foreign bodies are one of the commonest forms of ocular trauma, the majority of which occur due to occupational exposure. The aim of this study was to study the profile of patients with corneal foreign bodies. Materials and methods: A hospital based prospective study was conducted among 60 patients presenting to the ophthalmology outpatient department in Dhulikhel Hospital-Kathmandu University Hospital (DH-KUH) over a time span of 6 months. Demographic data of patients, clinical characteristics of foreign bodies and associated complications were noted. Results: Most of the patients were males (n=55) belonging to the 21-30 age group (n=24). Majority of them were workers in metal industries (n=26). Welding and cutting metal were implicated as the most common mode of injury (n=53). Conclusion: By virtue of this study, we identified the high risks associated with sustaining this form of ocular trauma. The incidence and hence the prevalence of corneal foreign body can be gradually levelled down if we aware the people about the associated complications and advise them to use protective eye wears (PEW).

A 42-year-old woman presented with fever, left ear pain, restricted mouth opening, difficulty in swallowing and inability to open her left eyelid for a period of 10 days. She was treated with antibiotics for the same at a local medical facility; however, a sudden decrease in her left eye vision prompted her to visit our tertiary centre. Her history was insignificant except for having multiple left ear syringing for an insect removal 10 days before onset of her current symptoms. On examination, she had ptosis of the left eye with chemosis, dilated pupil with only perception of light and restricted ocular mobility. Oral examination revealed trismus and bulge in the left peritonsillar region. Left ear examination revealed a large central perforation with mucopurulent discharge. CT of the neck with contrast demonstrated a collection in the left peritonsillar space with left internal carotid artery thrombosis. MRI of the brain with gadolinium revealed left cavernous sinus thrombosis with acute infarcts in the left frontal lobe. An emergency incision and drainage of the left peritonsillar abscess was performed. Culture grew broad aseptate fungal hyphae. Despite starting on antifungal therapy, she succumbed to her illness.

A measurable burden to the emergency ophthalmology department is represented by ocular trauma in pediatric patients. Traumatic cataracts still result in visual disability despite great advancements in diagnostic and treatment methods. Cataract surgery with intraocular lens (IOL) implantation aids in the improvement of visual acuity in such cases. Duration of trauma is an important prognostic factor for recovery of visual acuity before amblyopia sets in young patients with penetrating ocular injury.This video deals with the management of a case of partially absorbed traumatic cataract in a scenario of an old and neglected penetrating injury. This case had a corneal scar, ruptured anterior lens capsule, and posterior synechiae formation between the posterior pigmented epithelium of the iris and the lens capsule.In a case of penetrating ocular injury, one should always suspect violation of posterior lens capsule, weakened or broken zonules and retained intraocular foreign body. In this case, a circular capsulorhexis is difficult to attain. After staining the capsule with trypan blue dye, viscoelastic substance is instilled in the anterior chamber to have good control over the rhexis and to avoid rhexis run out. In case the rhexis runs off to the equator, a pair of Vannas scissors is used to cut the extended flap. The cataract is partially absorbed, white and soft in nature and is easily mobilized from the bag and eaten up via phacoaspiration. Before implantation of posterior chamber intraocular lens (PCIOL) in the sulcus, posterior synechiae are released by swiping a cyclodialysis spatula in the sulcus area. Visual axis is cleared by giving nicks in the posterior capsule to remove the central dense posterior plaque. Automated anterior vitrectomy is done and a three-piece PCIOL is implanted safely in the ciliary sulcus. Retained viscoelastic substance is washed, intracameral antibiotic is instilled, and the anterior chamber is subsequently formed via stromal wound hydration.Through this video, we tried to show how one should proceed with phacoaspiration with intraocular lens implantation in a case of traumatic cataract post penetrating injury in a sequential manner.https://youtu.be/20DbYUn_Fd8.

Objective To evaluate the relationship between the microbiological results of the vitreous humor and those of foreign body specimens in patients with intraocular foreign body (IOFB). Methods Seventy-one patients with an IOFB were included in this descriptive prospective case series. All patients underwent immediate IOFB removal. Vitreous sampling was performed during vitrectomy. Foreign bodies were placed directly into culture media for microbiological study. Results Thirteen (18.3%) patients developed endophthalmitis. The results of microbiological analysis of IOFB and vitreous humor specimens were negative in nine patients and positive in four. Fifty-eight (81.6%) patients with an IOFB had no evidence of endophthalmitis. Among them, seven patients showed positive microbiological results of foreign bodies with no manifestations of endophthalmitis. In five patients, a Staphylococcus epidermidis strain was observed in the culture of the IOFB specimen. Two patients had only positive smear test results of their vitreous humor specimen. Conclusion A correlation appears to be present between the microbiological results of the vitreous humor and IOFB specimens in patients with clinical findings of endophthalmitis but not in patients with a pure IOFB without clinical features of endophthalmitis. This may justify early use of intravitreal and intravenous antibiotics before the development of endophthalmitis.

A 34-year-old man, an electrician by occupation, presented with blurring of vision and pain in his right eye for the past 5 days. He had consulted elsewhere and was diagnosed with an intra-lenticular foreign body and was prescribed topical antibiotics, anti-inflammatory and antiglaucoma drops. The

Background The goals of this work were to report the demographic characteristics of patients with clinically diagnosed endophthalmitis with or without intraocular foreign bodies (IOFBs) and to analyze the causative microorganisms. Methods A retrospective analysis was conducted on 1257 patients with clinically diagnosed posttraumatic endophthalmitis who were admitted to Zhongshan Ophthalmic Center between January 1, 2013, and August 31, 2020. Results Of the 1257 patients with clinically diagnosed posttraumatic endophthalmitis, 452 (36.0%) patients had IOFBs. Male dominance was more common among the patients with IOFBs than the patients without IOFBs. The average age of the patients with IOFBs was older than that of the patients without IOFBs. The most common microbial pathogens in these two groups were Gram-positive cocci and Gram-negative bacilli. Gram-positive bacilli were more common in the patients with IOFBs than in those without IOFBs (17.9 vs. 9.4%), and Bacillus spp. accounted for 12.6 and 5.5%, respectively. Fungi were less abundant in the patients with IOFBs than in those without IOFBs (8.0 vs. 15.6%). Conclusions Patients with IOFBs were mostly male and older than those without IOFBs. Gram-positive bacilli were more common and fungi were less common in patients with IOFBs than in those without IOFBs.

We describe a technique for metallic intralenticular foreign body (ILFB) removal in a patient in whom there was no or minimal cataract formation or other complications. This technique required creating two corneal small incisions around the ILFB for inserting iris retractors to expose the ILFB. At the foreign body position, a clear corneal incision was made, and then the ILFB was removed with minimal manipulation by an intraocular magnet without complications. Because most occupational traumas occur in young people, this technique avoids the adverse outcomes of lens extraction in this age group.

Background Firework-related ocular injuries (FWROI) are a major cause of preventable visual impairment. This study aimed to analyze the occurrence and outcome of FWROI in Switzerland. Methods This retrospective multicenter study included patients with FWROI from seven centers in Switzerland from January 2009 to August 2020. Demographic information, type of injuries, medical and surgical treatments, the best corrected visual acuity (BCVA) at baseline and end of follow-up, occurrence and type of secondary complications, and duration of hospitalization were analyzed. Results A total of 105 patients (119 eyes) with a mean age of 27.1 ± 15.9 years were included in the study (71.4% male patients; 29.5% underage). Most injuries occurred around New Year’s Eve (32.4%) and the Swiss national holiday on 1 August (60.9%). The most common anterior segment findings were conjunctival or corneal foreign bodies (58%), whereas Berlin’s edema was the most common posterior segment finding (11.4%). Globe ruptures were found in four patients. The mean BCVA in all patients at first presentation was 0.4 ± 0.8 logMAR and improved to 0.3 ± 0.8 logMAR at last follow-up. A primary surgical intervention was performed in 48 eyes (40.3%). Hospitalization directly after the trauma was necessary for 18 patients for a mean of 5.8 ± 4.1 days, and a total of 4.9 ± 7.6 follow-up visits were needed. Conclusion This study provides the first data on FWROI in Switzerland, which are helpful for further preventive and educational programs and comparisons with other countries.

Intraocular foreign body (IOFB) removal becomes tricky if its large and impacted in the ocular coats. When confronted with such a combination, the vitreoretinal surgeon will need to modify the surgical plan. This surgical video describes one of such situation encountered during removal of a long wooden IOFB impacted in the ocular coats.The video describes a scenario when the surgeon becomes aware that injury to ocular structure is inevitable due to inherent length of the IOFB. However, a careful assessment of the situation helps the surgeon to identify how he could minimize the damage to the eye and not put vision at risk.A young boy presented with painful loss of vision in left eye since 15 days. Examination showed BCVA of 20/32 and limitation movement in up gaze. Fundus showed hazy media and an IOFB in superior quadrant. It was noted that IOFB was moving with eye movement. The impaction in sclera and extraocular extension was suspected. After pars plana vitrectomy, it was observed that IOFB was longer than what was measured by the scan and it was impacted in the coats. Removal using IOFB forceps further pulled the IOFB into vitreous cavity. A rectangular scleral window was created, IOFB was pushed towards opposite pars plana region to avoid injury to macula, optic nerve, lens and peripheral retina. The IOFB was then removed.The retinal tears were lasered. Three months following the surgery, he developed cataract, which needed surgery. His BCVA at the last follow up visit was 20/25 with attached retina.1. Limitation of movement in presence of linear IOFB shall raise a suspicion of IOFB being impacted in coats and possibility of its extraocular extension; 2.An oblique IOFB posterior to limbus, can have length more in transverse diameter of the eyeball. Though rarely used, an ab-externo approach can be a viable option in such a case to minimise injury to vital structure of the eye, particularly if the IOFB is severely impacted in sclera.https://youtu.be/2bF3WLd812o.

We present a case of a 29-year-old male night watchman complaining of sudden decreased vision, redness, and tearing of the left eye. On anamnesis, trauma was denied and personal past history was relevant for right eye enucleation due to an "eye injury" 8 years prior. At presentation, his visual acuity was 20/200 and intraocular pressure (IOP) was 10 mmHg. Slit lamp examination revealed a 1-mm inferonasal corneal wound and a localized lens opacity associated with extrusion and posterior extension of cortical material in the same quadrant. Echography confirmed posterior lens capsular bag puncture with hyperechogenic material in the anterior vitreous. Intraocular foreign body was ruled out. Topical anti-inflammatory and cycloplegic treatment was initiated with partial visual recovery, IOP rise, moderate anterior chamber inflammatory reaction, and an emergent posterior subcapsular cataract. A pars plana vitrectomy and lensectomy were performed. After surgery and recovery, best-corrected visual acuity with contact lens was 20/15. The patient was followed for 6 years, during which he returned 6 more times with a variety of new findings, such as new corneal leukoma, leaking corneal wounds, hypotony, choroidal folds, and choroidal detachments, each time with full visual acuity recovery. Some cases of ocular injury and self-mutilation have been described in the context of various psychiatric disorders. Self-inflicted injuries were suspected due to substance abuse, although the patient denied doing so. Referral to a psychiatrist was insisted on several occasions without success. However, potentially life-threatening complications may arise; therefore, psychiatric referral is imperative.

Purpose: To assess changes in the presentation patterns of posterior segment trauma during the COVID-19 pandemic from six tertiary eye care institutes of North and Central India. Methods: A multicenter, hospital-based, retrospective comparative analysis of patients presenting with posterior segment trauma was done during the COVID-19 (Group A) (March 25, 2020 - September 30, 2020) period and the pre-COVID-19 (Group B) (March 25, 2019 - September 30, 2019) period. Results: A total of 405 patients were diagnosed with posterior segment trauma (Group A: 206, Group B: 199). The time interval between onset of trauma and presentation was higher in Group A (16.59 ± 29.87 days) as compared to Group B (9.41 ± 19.19 days) (P = 0.004). A majority of patients in Group A had a history of prior consultation before presentation (P = 0.049). In Group A, 120 (58.2%) patients sustained ocular trauma at home as compared to 80 (40.2%) patients in Group B (P < 0.0001). Patients presenting with light perception were significantly more in Group A (43.7%) as compared to Group B (30.2%) (P = 0.004). In Group B, 37.6% patients had presenting visual acuity of counting finger or better as compared to 27.6% patients in Group A (P = 0.07). Patients in Group A had a significantly higher proportion of post-traumatic endophthalmitis with delayed presentation (P = 0.011) and retinal detachment (P = 0.041). Patients undergoing surgery for foreign-body removal were significantly fewer in Group A (P = 0.05). Conclusion: Although the number of patients presenting with posterior segment trauma was comparable in Groups A and B, a greater number of patients sustained home injuries during the COVID-19 pandemic. A majority of these patients had delayed presentation with poor presenting visual acuity and a higher tendency of retinal detachment.

Introduction: Intraocular foreign bodies (IOFBs) are a serious subset of open-globe injury that can result in visual loss. This study analyzed the epidemiology, clinical characteristics, and visual outcomes of patients with IOFBs in Southwest China. Methods: This retrospective study comprised 1,176 patients with the primary diagnosis of IOFBs who resided in Sichuan Province over a 10-year period. All data were collected from medical records and analyzed statistically. Results: The annual incidence for IOFBs was 0.14 per 100,000 (95% confidence interval 0.12–0.16 per 100,000) people in Southwest China. In that period, IOFBs accounted for 22.3% of all open-globe injuries. Working-age male patients accounted for 79.1% of all IOFBs patients and there had significant differences in age distributions between genders (p < 0.001). Metallic IOFBs were the most common (74.6%) IOFB, but there were significant differences in the materials of IOFBs between adults and children of different age-groups (p < 0.001). At discharge, 277 (23.6%) patients had increased visual acuity (VA) and 95 (8.0%) had no light perception. Initial VA p < 0.001), increasing wound size (OR, 1.3; p = 0.004), IOFBs in the posterior segment (OR, 2.6; p = 0.002) and existing complications (traumatic cataract, endophthalmitis, retinal detachment, or retinal break) were independent risk factors for final VA Conclusion: The incidence of IOFBs in Southwest China differed from global statistics. Adults and children had different clinical characteristics. Thus, their prevention strategies should be different.

Purpose The purpose of this paper is to provide a meaningful literature review about the epidemiology, pathogenesis, clinical signs, imaging and treatment of ocular siderosis (OS). Methods A computerized search from inception up to March 2020 of the online electronic database PubMed was performed using the following search strings: “ocular siderosis” and “siderosis bulbi”. The reference list in each article was analysed for additional relevant publications. Results OS is an uncommon cause of visual loss due to a retained ferrous intraocular foreign body (IOFB). It may develop from 18 days to years after a penetrating trauma that usually occurs during hammering. On average, patients are 22–25 years old, and the vast majority are male. The most common cause of OS development is delayed presentation by the patient or missed diagnosis of IOFB after trauma. The pathophysiology is not fully understood; nevertheless, iron deposition causes hydroxyl radical formation, which damages photoreceptors and retinal pigment epithelium. Moreover, iron damages retinal vessels with consequent inner retinal layers degeneration. The most frequent signs are iris heterochromia, pupillary mydriasis, cataract development and retinal arteriolar narrowing with pigmentary retinal degeneration. Electroretinogram signs, in particular, b-wave amplitude reduction, arise earlier than clinical signs. Orbital CT scans and ultrasonography play an essential role in detecting IOFBs. Treatment depends on the IOFB location and OS development. However, it is crucial to remove the IOFB after OS development because visual acuity and clinical signs may improve. Anterior segment IOFBs can be dislodged using an intraocular magnet (IOM) or forceps through limbal paracentesis. In contrast, posterior segment IOFBs require a pars plana vitrectomy and IOM or forceps to be removed through an enlarged sclerotomy or the limbus. Conclusion Recommending the usage of protective glasses and spreading knowledge about OS may further benefit patient care.

Resumo O estudo buscou analisar e estudar a prevalência e as circunstâncias de urgências e emergências oftalmológicas no Pronto Socorro do Hospital de Clínicas de Uberlândia da Universidade Federal de Uberlândia (HCU-UFU) e no Ambulatório Amélio Marques no período de agosto de 2016 a agosto de 2017. Faz-se necessário tal estudo, pois emergências oftalmológicas são importantes causas de morbidades na sociedade(1). Ademais, através dele políticas de prevenção poderão ser feitas, além de maior capacitação de profissionais a partir do conhecimento das principais causas de atendimento. A metodologia proposta incluiu a coleta de dados do prontuário, sendo colhidas as informações sexo, idade e ocupação/profissão. Trata-se de um estudo epidemiológico exploratório observacional predominantemente descritivo do tipo transversal. O trabalho evidenciou que o sexo masculino foi o mais acometido e a faixa etária mais incidente foi entre 19 e 45 anos. Das causas de procura pelo pronto-atendimento oftalmológico, o trauma ocular por corpo estranho é a mais comum havendo uma estreita relação com as atividades laborais (mecânicos e ferragistas). Dessa forma, os dados serão um recurso importante para o auxiliar na compreensão do perfil epidemiológico do pronto-atendimento oftalmológico visando otimizar a administração do mesmo e para estimular a adoção de políticas públicas de prevenção no âmbito da saúde do trabalhador. Abstract The study aimed to analyze and study the prevalence and circumstances of ophthalmic emergencies and urgencies in the Emergency Room of the Hospital de Clínicas de Uberlândia and the Central Ambulatory (Amélio Marques) of the Federal University of Uberlândia (HCU-UFU) from August 2016 to August 2017. This is a necessary study since ophthalmic emergencies are important causes of morbidities in society(1). In addition, this study will help to develop prevention policies and to make greater training of professionals based on knowledge of the main causes of eye emergencies. The proposed methodology included the collection of data from the medical record, with the information of sex, age and occupation/profession being collected. This is an observational, descriptive, transversal, exploratory epidemiological study. The study showed that males were the most affected and the most incident age group was between 19 and 45 years old. Eye trauma due to a foreign body is the most common cause of demand for ophthalmologic emergency care with a close relationship with work activities (mechanics and ironmongers). In this way, the data will be an important resource to assist in understanding the epidemiological profile of the ophthalmology emergency room in order to optimize its administration and to encourage the adoption of public prevention policies within the scope of occupational health.

Background Epidemiological studies focusing on occupational pathologies can be an important medium through which to bring about change with respect to workplace accidents, both in terms of prevention planning and management as well as the appropriate care following an accident. Ocular chemical burns benefit from urgent attention as, if not treated early and appropriately, the tissue of the eye and its functionality can be seriously compromised. The objective of this study was to collate epidemiological data on workplace ocular chemical burns which could in turn serve to identify key action points in terms of occupational health. Methods Cohort study with 604 cases of chemical burns to the eye occurring in the workplace between 2014 and 2015. Criteria inclusion were diagnosis of chemical burn, patient seen at the medical centre of the mutual society, workplace acquired ophthalmic pathology leading to the issuing of a sickness certificate. No exclusion criteria were defined. Results Ocular chemical burns were the second most common workplace eye injury (12.68%) behind foreign bodies in the eye (43.42%). Men accounted for 68.54% of cases of ocular chemical burns. In around 75% of cases, sickness certification was for less than 7 days, although 6 patients suffered permanent disability. The occupational sector which was most affected particularly the industry service industry. The economic costs with these workplace injuries were extracted. Conclusions Appropriate early medical assistance is essential. The production and distribution of clinical guides for health care workers could optimise first line assistance and mitigate possible training deficiencies. pre-print 170 KB

Background Posterior segment metallic intraocular foreign bodies (IOFBs) are a leading cause of visual morbidity and blindness, especially among young and middle-aged working populations. Here, we aimed to evaluate the surgical outcomes of the removal of such IOFBs that result from injuries. Methods In this retrospective study, 39 patients injured by metallic posterior segment IOFBs and who underwent primary repair procedures, vitrectomies, and IOFBs removal with or without procedures for traumatic cataract removal, scleral buckling and intraoperative tamponade application from January, 2008 to January, 2019. We analyzed the preoperative, intraoperative and postoperative related factors that affect the final visual outcomes. Results The mean age of the 39 patients was 40.51 ± 12.48 years with the male being predominent (100%).The mean preoperative vision measured 1.50 [Snellen Equivalent (SE), 20/645] ± 1.12 logMAR with the mean final vision measuring 0.93 (SE, 20/172) ± 1.09 logMAR. The related factors that were determined to affect the final visual outcomes included preoperative vision (P = 0.025), IOFB-related macula injuries (P = 0.001) and the development of postoperative complications (P = 0.005) especially retinal detachment (P = 0.002) with the mean final vision measuring 2.12 (SE, counting finger to hand motion) ±1.23 logMAR. Concerning the preoperative signs, the patients with preoperative endophthalmitis also obtained poor mean final vision measuring 1.30 (SE,20/400) ± 1.40 logMAR. Conclusion IOFB-related macula injuries and postoperative retinal detachment were important related factors of poor final visual prognoses in cases involving posterior segment metallic IOFBs. Removing IOFB as early as possible may prevent preoperative endophthalmitis which could lead poor final visions even without significance.

Purpose To describe the retention of large, tubular, nondissolving foreign bodies because of a complication of the intravitreal dexamethasone implant (Ozurdex). Methods This is a single-center, retrospective chart review of patients who were found to have retained, nondissolvable tubular foreign bodies in the vitreous cavity for more than 6 months (the expected dissolution time of the implants) after Ozurdex injections. Ocular symptomatology and multimodal imaging were reviewed. Results Five patients had retained, nondissolvable tubular foreign bodies in the vitreous that persisted for months (mean 28.2 months, range 9-67 months) after intravitreal injection of Ozurdex. Two patients were symptomatic due to the foreign bodies and chose alternate local therapy, but none of the patients opted for surgical explantation. Conclusion Persistent, nondissolving, tubular foreign bodies can be seen in the vitreous cavity for years after injection of the Ozurdex implant. Clinicians should be aware of this complication that has the potential to cause visual symptoms and ocular morbidity.

Background Intraorbital metallic foreign bodies have varied clinical presentations. Here, we report the unusual case of intraoperative evidence of spontaneously healed posterior scleral perforation in a severe ballistic trauma without previous instrumental signs of penetrating wound and complete visual restoration after surgery. Case presentation The patient was hit by several lead hunting pellets in the chest, abdomen, limbs, face and orbit. Computed Tomography (CT) images revealed the presence of a pellet within the orbitary cavity, close to the optic nerve, with no signs of penetrating ocular wound. While performing vitrectomy for severe vitreous hemorrhage, a point of strong adherence between a old hemorrhage and retinal surface was identified and managed conservatively, as it was attributed to trauma related-impact area. So, lead foreign body took an unusual trajectory impacting the globe and finally lodging back in the deep orbitary cavity, in absence of significant ocular injury and with visual prognosis preservation. Conclusions Our findings provide further information on orbital injuries from airguns, a theme of growing popularity and concern. Intraoperative recognition of hardly removable old hemorrhagic clot as self-blockage site of posterior scleral penetrating trauma, allowed for surgical stabilization and minimal solicitation of the area to avoid inadvertent perforation.

Background and Objectives: Open globe injuries (OGI) remain an important cause of visual impairment and loss, impacting all ages. A better understanding of the factors influencing visual outcomes is important in an attempt to improve the results of the treatment of OGI patients. The author aimed to contribute to this knowledge with the analysis of clinical characteristics, prognostic factors, and visual outcomes of their cohort of OGI patients. Materials and Methods: A retrospective medical record review was performed for 160 patients (161 eyes) who sustained an open globe injury between January 2015 and December 2017 and presented to the Hospital of Lithuanian University of Health Sciences. Data analyzed included age, sex, type, cause, place of OGI, initial visual acuity (VA), final best-corrected visual acuity (BCVA), and tissue involvement. Open globe injuries were classified using the Birmingham Eye Trauma Terminology (BETT) and Ocular Trauma Classification System (OTCS). Univariate analysis was conducted to evaluate the prognostic factors. Results: The mean age of the patients was 41.9 years. The male-to-female ratio was found to be 8.4:1. The home was the leading place of eye injury (59.6%), followed by an outdoor environment (14.3%) and workplace (11.8%). Penetrating injury accounted for 43.5%, followed by intraocular foreign body injury (39.1%) and globe rupture (13%). Overall, 19.5% of patients regained a good final vision of ≥0.5, but for 48.1% of them, eye trauma resulted in severe visual impairment (BCVA ≤ 0.02). In the univariate analysis, a bad visual outcome of less than 0.02 was correlated with bad initial VA, iris dialysis, hypotony, vitreous hemorrhage, and vitreous prolapse at presentation. Phthisis bulbi was correlated with eyelid laceration, iris prolapse, iris dialysis, hyphema, vitreous prolapse, vitreous hemorrhage, and choroidal rupture at initial examination. Conclusions: Open globe injury remains an important preventable cause of ocular morbidity. This study provides data indicating that open globe injuries are a significant cause of visual impairment in our research group.

BACKGROUND The aim of this study was to analyze the value of ocular endoscopy in detecting and extracting intraocular cilia in patients with ocular trauma. MATERIAL AND METHODS We retrospectively analyzed data on identification and extraction of 46 intraocular cilia in 16 eyes with open-globe injury during endoscope-assisted vitrectomy. RESULTS A total of the 16 patients with open-globe injury were operated on from September 2002 to June 2019. The cornea in 14 eyes was cloudy. Two eyes had endophthalmitis and 13 eyes had retinal detachment. A total of 46 cilia were extracted through direct observation under the ocular endoscope during vitrectomy 1 to 68 weeks after injury. The number of cilia per eye varied from 1 to 10. Most of the cilia were located in or near the wound. Postoperative IOP was normal in 14 patients. The follow-up after surgery showed hypotony in only 2 eyes (7.2 and 5.8 mmHg, respectively). Compared with preoperative intraocular pressure, there was a statistically significant difference. The postoperative visual acuity improved in 12 eyes and remained unchanged in 3 eyes. The vision after surgery was significantly improved compared with that before surgery (P=0.006). The intraocular pressure increased significantly after operation (P0.001). And no glaucoma or retinal detachment or endophthalmitis was found. No eyes needed additional vitreous surgery. CONCLUSIONS Ocular endoscopy allows surgeons to detect intraocular cilia that were no undetected by CT or B-ultrasound preoperatively in time and to extract them effectively. It improves performance of vitrectomy in the presence of a cloudy cornea and also prevents exogenous endophthalmitis. The vision of patients with ocular trauma was improved.
