Purpose: To evaluate the clinical outcome of surgical treatment for macular serous detachment associated with optic disc pit with pars plana vitrectomy (PPV) without laser photocoagulation on the temporal edge.
Methods: Vitrectomy was performed in 8 eyes of 8 patients (mean age 27.25 years; range 12-57 years) with unilateral macular detachment associated with optic disc pit. All patients underwent pars plana vitrectomy (cases 1, 2, 3, and 4, PPV 20 G; cases 5, 6, 7, and 8, PPV 25 G), internal limiting membrane (ILM) peeling, and SF6 20% gas tamponade (case 1 was treated with silicone oil tamponade). Endolaser on the temporal margin of the optic disk was not performed. Every patient was observed for a follow-up period of 59.25 months after surgery. Statistical analysis was carried out using Student t test paired data. p Value <0.05 was considered to be significant.
Results: Complete retinal reattachment was achieved in 7 of 8 patients. Case 8 was operated 11 months ago and he still has a small area of subretinal fluid not completely reabsorbed. Mean preoperative best-corrected visual acuity (BCVA) was 20/83 and the mean postoperative BCVA was 20/40. Mean preoperative foveal thickness was 973 μm and mean postoperative foveal thickness was 363.5 μm. Case 7 developed a macular hole after treatment.
Conclusions: Pars plana vitrectomy, ILM peeling, and endotamponade (SF6 20% gas) without endolaser on the temporal edge of optic disc is an effective treatment. This procedure achieved successful anatomical and functional results.

Purpose: The purpose of this study was to develop and validate a deep-learning model for noninvasive anemia detection, hemoglobin (Hb) level estimation, and identification of anemia-related retinal features using fundus images.
Methods: The dataset included 2265 participants aged 40 years and above from a population-based study in South India. The dataset included ocular and systemic clinical parameters, dilated retinal fundus images, and hematological data such as complete blood counts and Hb concentration levels.

The aim of the study was todescribe the clinical features, optical coherence tomography (OCT) and fundus autofluorescence (FAF) imaging in patients with choroidal and retinal tumors. Ninety eyes of 89 patients with treatment-naive macular, midperipheral, and juxtapapillary choroidal and retinal tumors were retrospectively included in the study. All patients underwent a complete ophthalmic examination, B-mode ultrasonography, OCT, and FAF imaging.

Purpose: This multicenter study aimed to investigate the clinical characteristics and factors associated with specific viral pathogens in patients with acute retinal necrosis (ARN).
Methods: A retrospective multicenter cohort study included ARN patients who underwent aqueous or vitreous polymerase chain reaction (PCR) testing. Multivariable mixed-effects Poisson regression was used to identify factors associated with viral pathogens.
Semaglutide, type 2 diabetes, and the risk of nonarteritic anterior ischemic optic neuropathy.
Int J Retina Vitreous

Brazilian Diabetes Society, São Paulo, Brazil.
In the last months, conflicting evidence on a possible association between the use of semaglutide and incident nonarteritic anterior ischemic optic neuropathy (NAION) has emerged. A recently published study, which evaluated all patients with type 2 diabetes in Denmark, has shown with robustness that once-weekly semaglutide doubles the five-year risk of NAION. In this comment, the new evidence is discussed, along with practical implications for type 2 diabetes patients.

Paired box 2 ()-related disorder, also known as renal coloboma syndrome, is a variably penetrant autosomal dominant condition, associated with renal and ophthalmological abnormalities. We report a child with -related disorder who presented atypically with acute ataxia on a background of stage 3 chronic kidney disease. Extensive biochemical, radiological and gene agnostic rapid trio exome sequencing was non-diagnostic.
