Article Abstract

Optic disc pit maculopathy is a serious complication of congenital optic disc pits, often resulting in significant vision loss due to intraretinal and subretinal fluid accumulation. This case report describes a 35-year-old woman with progressive visual decline in her right eye. Examination revealed optic disc pit maculopathy with marked central foveal thickness (634 μm) and a best-corrected visual acuity of 20/100. The patient underwent pars plana vitrectomy, induction of posterior vitreous detachment, selective internal limiting membrane peeling to create a temporal flap, inversion of the flap over the optic disc pit, and gas tamponade with 25% sulfur hexafluoride. At 8 months postoperatively, there was complete resolution of retinal fluid, reduction in central foveal thickness to 261 μm, and best-corrected visual acuity improved to 20/20. These anatomical and functional gains were maintained at 16 months, highlighting the efficacy and safety of the inverted ILM flap technique in optic disc pit maculopathy management.

Introduction: Vision language models (VLMs) combine image analysis capabilities with large language models (LLMs). Because of their multimodal capabilities, VLMs offer a clinical advantage over image classification models for the diagnosis of optic disc swelling by allowing a consideration of clinical context. In this study, we compare the performance of non-specialty-trained VLMs with different prompts in the classification of optic disc swelling on fundus photographs.

This systematic review examines the potential association between semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist, and the development of non-arteritic anterior ischemic optic neuropathy (NAION). Nine studies were included, consisting of retrospective cohort analyses, case series, and pharmacovigilance reports. Findings across the literature were inconsistent, with some studies reporting an increased risk while others found no significant association.

Background Increased intracranial pressure (ICP) can be reliably detected at the bedside using the optic nerve sheath diameter (ONSD). The functional outcome in stroke patients can be predicted with the use of acute-phase ONSD dynamics. Objectives To determine the predictive accuracy of ONSD on days 0, one, and three for the prognosis of ischemic stroke patients presented to emergency medicine as measured by Modified Rankin Scale (mRS) score.

Background: The α-actinin-4 (ACTN4) gene encodes an actin-binding protein, which plays a crucial role in maintaining the structure and function of podocytes. Previous studies have confirmed that ACTN4 mutations can lead to focal segmental glomerulosclerosis-1 (FSGS1), a rare disease primarily manifesting in adolescence or adulthood, characterized by mild to moderate proteinuria, with some cases progressing slowly to end-stage renal disease.

From the Vitreous, Retina, Macula Consultants of New York, New York, NY.

Purpose: To reassess the anatomic basis of optic disc pit maculopathy (OPM) using swept-source optical coherence tomography (SS-OCT) and to characterize the broader structural abnormalities comprising the optic pit complex.

Methods: Sixteen patients with OPM were imaged using a high-resolution SS-OCT system (DREAM OCT). Cross-sectional and volume-rendered scans were analyzed for lamina cribrosa defects, intraneural cavitations, and pathways for fluid entry into or beneath the retina.
