Treatment of vision-threatening branch retinal artery occlusion following coronary angioplasty with surgical displacement of embolus.

Purpose: To report a successful case of vision restoration and macular reperfusion following branch retinal artery occlusion (BRAO) using pars plana vitrectomy with undermining the artery off the retinal bed.
Methods: This case report involves a 75-year-old patient who was diagnosed immediately with BRAO following cardiac catheterization procedure. An embolus at the superior retinal artery bifurcation was noted.
Predicting branch retinal vein occlusion development using multimodal deep learning and pre-onset fundus hemisection images.

Branch retinal vein occlusion (BRVO) is a leading cause of visual impairment in working-age individuals, though predicting its occurrence from retinal vascular features alone remains challenging. We developed a deep learning model to predict BRVO based on pre-onset, metadata-matched fundus hemisection images. This retrospective cohort study included patients diagnosed with unilateral BRVO from two Korean tertiary centers (2005-2023), using hemisection fundus images from 27 BRVO-affected eyes paired with 81 unaffected hemisections (27 counter and 54 contralateral) for training.

Proliferative vitreoretinopathy (PVR) is a major cause of rhegmatogenous retinal detachment repair failure. Despite many attempts to find therapeutics for PVR, no pharmacotherapy has been proven effective. Steroids, as the epitome, show uncertain clinical effectiveness, which lacks an explanation and hints at unappreciated mechanisms of PVR.

Color vision, which is mediated by cone photoreceptors in vertebrates, is essential for perceiving the external environment. Bisphenol A (BPA) and its substitute bisphenol S (BPS) have been widely used worldwide, while the evaluation of their safety, especially the newly discovered visual toxicity mechanism caused by them in recent years, has not been clearly explored. In the present study, we investigated the effects of BPA treatment (1, 10, and 100 μg/L) on cone cell development and function to evaluate visual toxicity.

Background: While vaccination remains crucial in mitigating the impact of the COVID-19 pandemic, several ocular adverse events has been reported, including Acute Zonal Occult Outer Retinopathy (AZOOR) complex.
Case Presentation: A 31-year-old female presented declined best corrected visual acuity (BCVA) and flashes in both eyes three days following second recombinant mRNA COVID-19 vaccine (Moderna). Fundus autofluorescence (FAF) illustrated speckled hyper-AF lesions surrounding right eye torpedo maculopathy site and hyper-AF lesions in the left macula.
