Purpose: To report two cases of diffuse unilateral subacute neuroretinitis (DUSN) from northern Iran and to present the sequential imaging.
Methods: Two patients with large subretinal nematodes were evaluated and managed in our clinic. Serial fundus photography and optical coherence tomography (OCT) imaging were used to document the course of the disease.
Objective: To assess the noninferiority of biosimilar aflibercept (P041, CinnaGen) to the originator aflibercept (AFL, Regeneron) in terms of efficacy, safety, and immunogenicity.
Design: This was a phase Ш, 52-week, multicenter, randomized, double-masked, and active control trial involving eyes in a 1:1 ratio.
Subjects: Patients with active subfoveal choroidal neovascularization secondary to age-related macular degeneration randomized into the 2 groups of P041 and AFL.
Background: The basis of the overcorrecting minus lens is to induce compliance and consequently prevent constant exotropia. Some previous studies advocated early surgical therapy and others suggested over-minus treatment. Our purpose is to evaluate the success rate of the over-minus lens.

- The study examined the prevalence and factors associated with cataract among adults aged 50 and older in Gilan Province, Iran, finding that 50.50% were affected by cataracts, primarily those over 80 years old.
- It involved nearly 3,000 residents with comprehensive examinations and questionnaires to gather data on age, gender, previous surgery, and sunlight exposure.
- Key findings indicated that older age and having a history of eye surgery increased cataract risk, while more sunlight exposure was linked to a lower prevalence of cataracts.
Article Synopsis
- A study conducted in 2014 examined refractive errors (RE) among individuals aged 50 and older in Gilan, Iran, analyzing factors like age, BMI, and education related to these errors.
- The study included 2,587 participants and found prevalence rates of 19.2% myopia, 48.6% hyperopia, and 57.4% astigmatism, with higher incidences noted in those over 70 years.
- Results indicated that older age and specific types of cataracts increased the risk of myopia, while higher BMI was linked to a greater risk of hyperopia, with increased education levels associated with reduced myopia risk.
Purpose: To present a relatively rare case of retinal toxicity and consequent severe vision loss due to Closantel ingestion.
Case Report: A 37-year-old female presented with sudden painless decrease vision in both eyes. She had no previous history of medical disease and denied any trauma.
Background: To determine the applicability of current international and national retinopathy of prematurity (ROP) screening guidelines and to identify a suitable community-based screening criterion.
Methods: A retrospective study on premature neonates (≤37 weeks gestation) referred to a tertiary eye hospital ROP clinic in the north of Iran was conducted over a 10-year period. Neonates were classified as no ROP, with ROP and type 1 ROP.
Article Synopsis
- - The case discusses a 12-year-old boy with linear scleroderma called "en coup de sabre," who experienced vision loss in the area affected by the condition.
- - An eye examination revealed serious issues like vitreous hemorrhage and telangiectatic vessels, indicating a Coats'-like response, which was confirmed by fundus fluorescein angiography showing vascular abnormalities.
- - The patient was treated successfully with intravitreal bevacizumab and targeted retinal photocoagulation, leading to significant visual recovery over a 12-month follow-up; this highlights the need for careful eye examinations for conditions related to en coup de sabre.
Purpose: To compare the outcomes of phacoviscocanalostomy and viscocanalostomy in patients with primary open angle glaucoma.
Methods: This non randomized, prospective comparative study included 168 eyes of 168 patients with primary open angle glaucoma (POAG). Phacoviscocanalostomy was performed in 94 eyes with POAG and cataract and viscocanalostomy was performed in 74 eyes with POAG.
Purpose: To estimate carrier frequencies of mutations p.Gly61Glu and p.Arg368His, respectively, in Talesh and the east of Guilan province in Iran with a maximum error of 2%.
View Article and Find Full Text PDFPurpose: Viscocanalostomy represents an alternative to standard penetrating glaucoma surgery. The aim of this study is to compare the outcomes of combined phacoemulsification and viscocanalostomy in eyes with primary open-angle glaucoma (POAG) versus eyes with pseudoexfoliation glaucoma (PEXG).
Methods: In this prospective non-randomized comparative study, eyes with cataract and POAG or PEXG were enrolled.
Article Synopsis
- Usher syndrome is a common cause of combined vision and hearing problems, but it can be tricky to diagnose because other similar conditions exist.
- Researchers studied 59 patients from Mexico and Iran who had both retinal degeneration and hearing loss to understand the genetic causes better.
- They found that most patients had specific gene mutations linked to Usher syndrome, with a high success rate in identifying these genetic issues, which can help guide treatment and counseling for the affected families.
Article Synopsis
- The study assessed the prevalence and factors associated with Age-Related Macular Degeneration (AMD) in a sample of 2975 residents aged 50 and older in Gilan Province, Iran, in 2014.
- The findings revealed an age- and sex-standardized prevalence of 13.2% for early AMD and 0.7% for late AMD, with increased age shown to correlate with higher odds of developing any, early, and late AMD.
- This research highlights the need for improved eye care services and preventive measures in light of the aging population in Iran.
Purpose: To conduct an assessment of avoidable blindness and diabetic retinopathy (DR) in Gilan, 2014.
Methods: A cross-sectional population-based survey was performed on a representative sample of urban and rural individuals aged ≥50 years of the province. Blindness was defined as presenting visual acuity (PVA) <3/60 in the better eye.
Purpose: To report the incidence and risk factors for retinopathy of prematurity (ROP) among preterm infants referred to Amiralmomenin Eye Hospital, Rasht, Iran.
Methods: This cross-sectional retrospective study included all preterm infants with birth weight ≤2500 g and/or gestational age ≤36 weeks who had been referred to our facility for ROP screening over a five year period from September 2005 to September 2010. Possible risk factors and findings related to eye examinations were extracted and analyzed.
Purpose: To compare the visual and anatomical outcomes of four surgical techniques to manage pseudophakic and aphakic retinal detachment (PARD).
Methods: In a multicenter randomized clinical trial, 211 eyes of 211 patients with PARD and proliferative vitreoretinopathy (PVR) grade B or less were randomly assigned to one of the four treatment groups: (1) scleral buckling (SB), 50 eyes, (2) vitrectomy without band, 51 eyes, (3) vitrectomy with encircling band (EB), 58 eyes, and (4) triamcinolone acetonide (TA) assisted vitrectomy, 52 eyes. Patients were followed for 12 months after the surgery.
Purpose: To evaluate the intra- and interobserver reproducibility of peripapillary retinal nerve fiber layer (RNFL) thickness measurements before and after pupil dilation using spectral-domain optical coherence tomography (SD-OCT).
Methods: In this observational case series, 44 eyes of 44 healthy subjects were scanned by two trained operators on the same day, using Cirrus SD-OCT (Carl Zeiss Meditec, Dublin, CA, USA). Three scans were obtained before and after pupil dilation by each operator.
Purpose: To compare the incidence of adverse reactions following rapid versus slow fluorescein injection for fundus angiography.
Methods: This randomized controlled trial was performed on 500 patients with retinal vascular disorders. Subjects with central serous retinopathy, age-related macular degeneration and retinal pigment epithelial changes were excluded.
Objective: To compare the efficacy of the classic treatment of ocular toxoplasmosis (pyrimethamine, sulfadiazine, and prednisolone) with a regimen consisting of trimethoprim/sulfamethoxazole (co-trimoxazole) plus prednisolone.
Design: Prospective randomized single-blind clinical trial.
Participants: Fifty-nine patients with active ocular toxoplasmosis were randomly assigned to 2 treatment groups: 29 were treated with pyrimethamine/sulfadiazine, and 30 patients received trimethoprim/sulfamethoxazole.
