Abstract Purpose This study aimed to investigate the role of Whitnall’s ligament position in the success of levator resection surgery in congenital ptosis. Methods It was an interventional case series on patients with congenital ptosis who underwent levator muscle resection in Farabi Eye Hospital (2020–2022). Patients with incomplete follow-up, a history of trauma, poor Bell’s phenomenon, previous ocular and lid surgeries, poor levator function (≤ 4mm), and syndromic ptosis or systemic diseases were excluded. During the surgery, several factors, including the distance between Whitnall’s ligament and the upper edge of the tarsus (W-distance), the vertical length of the tarsus (T-length), and the amount of levator muscle resection (LMR), were measured. A successful outcome was defined as the inter-eye difference of margin reflex distance-1 (MRD1) ≤ 1 and post-op MRD1 ≥ 3 OR the inter-eye difference of MRD1 ≤ 0.5 with any value of post-op MRD1 in unilateral cases and Postop-MRD1 > 3 in bilateral cases during the 3-months period. Results Thirty four eyes of 34 patients were included, and 79.4% of patients achieved successful outcomes. In univariate analysis, Preop-MRD1 and Preop-LF had meaningful negative correlations with the amount of LMR to reach the successful outcome (p

Objective: This study aimed to evaluate the Iranian ophthalmologists’ knowledge of prescribing prophylacticantibiotics to patients with open globe injury (OGI) in Iran.Methods: In this cross-sectional study, we utilized a questionnaire to evaluate the ophthalmologists’ knowledgeabout prescribing antibiotics as prophylaxis. This survey was conducted in Tehran and its suburbs. Thequestionnaire included demographic information as well as ophthalmologists’ knowledge levels. Cronbach’salpha was used to determine its validity and reliability. The obtained data were analyzed using SPSS 24.0.Results: Of 192 subjects, 111 (35 women, 76 men) were included. About 65 (58.6%) specialists and 45 (41.4%)subspecialists with different orientations completed the questionnaires. The total knowledge score was13.04±2.96. The following are the results of ophthalmologists’ responses to questions regarding the cornea/scleral injury (1.09±1.72), prophylactic antibiotics administration (2.79±1.11), the infectious agents in eyesurgeries (3.21±1.49), diagnosis and treatment (2.84±0.944), and the effects of ocular antibiotics as well as theirproper dosage (2.96±2.35). There was no significant relationship between some demographic information suchas sex, working hours, workplace, and the number of studied articles (p>0.05). In addition, ophthalmologistswith less work experience had significantly higher levels of knowledge than those with more work experience.Conclusion: The findings indicated that the majority of ophthalmologists had a basic knowledge of prescribingprophylactic antibiotics in OGI.

Abstract Background Epithelial downgrowth is a rare complication after Descemet stripping automated endothelial keratoplasty (DSAEK), which usually leads to poor visual outcome despite multiple available options of treatment. Case presentation A 50-year-old man underwent DSAEK procedure due to pseudophakic bullous keratopathy. Three months later, the patient presented with gradual visual loss; slit-lamp examination revealed detachment and folding of the DSAEK lenticule, which was confirmed by anterior segment optical coherence tomography. On confocal scanning, epithelial cell sheets were detected in the interface leading to the wrinkling of the donor tissue and donor detachment. Surgical debridement and transient fixating with straight 10–0 prolene needles were performed followed by air injection into the anterior chamber. The cornea turned clear in the one-year follow-up with uncorrected-visual acuity of 20/30 and best-corrected visual acuity of 20/25. Conclusions Early diagnosis and treatment of epithelial downgrowth may be associated with a good prognosis and prevent from more aggressive treatments such as repeat of grafting. In this case, mechanical debridement and transient fixation of lenticule by 10–0 prolene needles was performed to manage post-DSAEK epithelial downgrowth and lenticule detachment, which was successful without requiring of additional re-grafting. It seems this is a feasible technique with acceptable long-term outcomes.

Abstract Background Keratoconus (KCN) is a common ectatic disorder of the cornea. Corneal collagen cross-linking (CXL) is used as an effective option to slowdown the disease progression. Although CXL is considered a safe procedure, corneal endothelial damage, especially in corneal thickness of less than 400 μm, has been reported. Case presentation A 25-year-old man known case of KCN was referred with complaints about blurred vision and discomfort of the right eye 3 days after performing CXL. The preoperative thinnest point was 461 μm. His presenting BCVA was CF at 1 m. Examination showed central corneal edema and stromal haziness. ASOCT demonstrated increased central corneal thickness and very deep CXL line. In the confocal scan, anterior stroma showed hyper-reflective lines without recognizable cells and nerves, the middle stroma showed rare active and edematous keratocytes and a hyper-reflective reticular pattern with elongated keratocytes and needle-like structures involving the posterior stroma indicated increased depth of CXL. To manage the patient, debridement of loosened epithelium was done. Non-preservative steroid 1% eye drop was prescribed frequently. The corneal edema was completely resolved during 2 months with no need for surgical procedure and BCVA of 20/30 in his right eye. Conclusion The corneal thickness of more than 400 μm cannot guarantee the absence of corneal edema after corneal collagen cross-linking, which can pertain to several factors such as inadvertently using of higher energy as well as the incorrect observance of all guidelines, instructions, and other precautions, even by a trained surgeon.

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.

Abstract Background Acute retinal necrosis is considered a rare infectious uveitis. This condition is usually caused by varicella-zoster virus or herpes simplex virus. Acute retinal necrosis caused by co-infection with multiple viruses is extremely rare. Herein, we report a case of acute retinal necrosis caused by co-infection with herpes simplex virus (type I and II) and varicella-zoster virus (VZV) in a natalizumab-treated patient due to multiple sclerosis. Case presentation An adult man presented with a complaint of decreased vision of the right eye from 12 days ago. He was a known case of multiple sclerosis receiving natalizumab. Examination of the right eye revealed severe conjunctival injection, fine diffuse keratic precipitates, 3 + anterior chamber and vitreous cells, elevated intraocular pressure (26 mmHg), a blurred optic disk with hemorrhagic patches, and occlusive vasculitis plus confluent necrotizing patches in the peripheral retina compatible with diagnosis of acute retinal necrosis. He underwent anterior chamber and vitreous tap, and real-time PCR detected HSV I & II and VZV on the vitreous specimen. A second PCR showed the same result. After neurological consultation, natalizumab was discontinued and intravenous acyclovir was started followed by oral acyclovir and oral prednisolone to control the disease, which was successful. Conclusions Although rare, multiple-viral infection should be considered in the physiopathology of acute retinal necrosis, especially in immunosuppressed patients.

Although corticosteroids are currently the first-choice drug for thyroid eye disease (TED), in 20–30% of cases, patients show poor or non-existent responses, and when the drug is withdrawn, 10–20% of patients relapse. Thus, in this study, we aimed to investigate the efficacy of the combined use of mycophenolate mofetil (CellCept®) and low dose oral prednisolone in patients with moderate to severe Graves' orbitopathy (GO). For the first time, we investigated the relationship between TED-related parameters and proptosis reduction. In a prospective, non-randomized, interventional case series, 242 patients with moderate-to-severe GO were, assigned to receive oral prednisolone (5 mg/ d) and mycophenolate mofetil (CellCept®) (one 500 mg tablet twice per day according to the therapeutic response). The patients were monitored regularly during the 3rd, 6th, 12th, and 18th month of treatment. The main outcome measures were the clinical activity score (CAS), intraocular pressure (IOP), diplopia, proptosis and visual acuity. We also assessed the relationship between the main outcomes with proptosis changes and time to improvement (months). Adverse effects were recorded during each visit. The clinical response rate increased from 67.7% on the third month to 89.2% on the sixth month, and 94.2% on the 12th month. This therapeutic response continued until the 18th month of follow-up. The CAS responses [disease inactivation (CAS

Objective To examine the prognostic factors and features of post-traumatic endophthalmitis. Methods This retrospective study enrolled adult patients (>18 years old) diagnosed with post-traumatic endophthalmitis. Their medical records were reviewed and the patient demographic characteristics, features of injury, management, outcomes and microbiology data were analysed. Results A total of 131 eyes from 131 patients were enrolled. Post-traumatic endophthalmitis was more common in male patients (122 of 131 patients: 93.1%), in those aged 30–44 years (51 of 131 patients: 38.9%), in those injured with a metallic object (86 of 131 patients; 65.6%), in those with a penetrating injury (90 of 131 patients; 68.7%) and those that were injured at work (106 of 131 patients; 80.9%). The mean ± SD time of presentation to the hospital and developing endophthalmitis was 40.60 ± 19.32 h and 5.19 ± 2.55 days, respectively. Of the cultures, 84 of 131 (64.1%) were negative and 22 of 131 (16.8%) were positive for Staphylococcus species. Patients with delayed presentation, an intraocular foreign body, traumatic cataract, retinal detachment, larger wounds, positive smears and cultures and work-related injuries had worse outcomes. Conclusion Immediate presentation to an ophthalmic centre and timely diagnosis and intervention may lead to better outcomes.

Endophthalmitis is the most serious complication of cataract surgery. A cluster of endophthalmitis is a devastating event for surgeons. Pseudomonas aeruginosa is the main causative pathogen of Gram-negative endophthalmitis, which can be suggestive of the occurrence of an outbreak. Ten patients diagnosed with endophthalmitis after cataract surgery performed by one surgeon were analyzed in this study. At presentation, five patients had obvious clinical findings of endophthalmitis with visual acuity of light perception, two patients had poor light perception/no light perception of vision complicated by concomitant keratitis, and three patients had earlier signs of infection (e.g., a lower degree of anterior chamber and vitreous cells, better presenting visual acuity, and greater visibility of the fundus). Investigations revealed that the source of infection was growth of P. aeruginosa on the phaco probe. All of the surgeries had been performed by the same contaminated probe without sterilization between surgeries. This finding emphasizes the importance of strict adherence to sterility protocols during high-risk surgeries such as intraocular surgeries. Additionally, this report aims to emphasize to surgeons that negligence of simple but vital steps of sterility for any reason, such as limitations in time or equipment, can lead to catastrophic events.

Purpose: We aimed to present the ophthalmic manifestations of neuro-metabolic disorders. Methods: Patients who were diagnosed with neuro-metabolic disorders in the Neurology Department of Mofid Pediatric Hospital in Tehran, Iran, between 2004 and 2014 were included in this study. Disorders were confirmed using clinical findings, neuroimaging, laboratory data, and genomic analyses. All enrolled patients were assessed for ophthalmological abnormalities. Results: A total of 213 patients with 34 different neuro-metabolic disorders were included. Ophthalmological abnormalities were observed in 33.5% of patients. Abnormal findings in the anterior segment included Kayser–Fleischer rings, congenital or secondary cataracts, and lens dislocation into the anterior chamber. Posterior segment (i.e., retina, vitreous body, and optic nerve) evaluation revealed retinitis pigmentosa, cherry-red spots, and optic atrophy. In addition, strabismus, nystagmus, and lack of fixation were noted during external examination. Conclusion: Ophthalmological examination and assessment is essential in patients that may exhibit neuro-metabolic disorders.

To report two cases of bilateral conjunctival granuloma with histopathological features of the Splendore-Hoeppli phenomenon and review of the literature. Two female patients, one with a history of pulmonary eosinophilic infiltration and another with a history of vernal keratoconjunctivitis, presented with bilateral cream to yellow colored nodules in the superior bulbar conjunctiva. Histopathologic examination revealed characteristic features of the Splendore-Hoeppli phenomenon manifesting as zones of amorphous eosinophilic material surrounded by aggregations of epithelioid histiocytes, giant cells, eosinophils and lymphoplasmacytic infiltrates. No evidence of infectious organisms was found. Our report adds to non-infectious cases of conjunctival Splendore-Hoeppli phenomenon. Previous history of allergic disorders may have contributed to the occurrence of this entity.
