Purpose: To investigate the relationship between the characteristics of optic disc rotation and visual field (VF) progression in patients with myopic open-angle glaucoma (OAG).
Methods: We included 53 eyes from 53 myopic OAG patients who were followed-up over a 3-year period. The characteristics of optic disc rotation including the degree of optic disc rotation, direction of optic disc rotation, and optic disc rotation-VF defect correspondence were investigated. The rates of global and regional VF progression were compared with different characteristics of optic disc rotation.
Results: Thirty-seven eyes (69.8%) showed inferior optic disc rotation and 41 (77.4%) eyes showed optic disc rotation-VF defect correspondence. The inferiorly rotated optic discs with corresponding superior VF defect had faster VF progression in the superior peripheral region (P = 0.028) and superiorly rotated optic discs with corresponding inferior VF defect had faster VF progression in the inferior peripheral region (P = 0.031). The VF progression was restricted to the superior hemifield in the eyes with inferiorly rotated optic discs and corresponding superior VF defects.
Conclusion: In myopic OAG patients, the direction of optic disc rotation might predict faster VF progression in the corresponding peripheral region.

Peripapillary pachychoroid syndrome (PPS) is a recently described condition, classified within the pachychoroid disease spectrum characterized by focal or diffuse thickening of the choroid due to dilation of choroidal vessels in the Haller's layer (pachyvessels), thinning of the choriocapillaris and the Sattler's layer, and accompanied by increased choroidal permeability and damage to the retinal pigment epithelium. Unlike other pachychoroid diseases that involve changes in the central retina, PPS presents with choroidal thickening and intra- or subretinal fluid located nasally in the macular region, near the optic disc. This review aims to summarize and analyze current data on the clinical features, pathogenesis, and treatment options for PPS found in the literature.

Introduction: This study aims to summarize the retinal and choroidal microvascular features detected by optical coherence tomography angiography (OCTA) in the affected and fellow eyes of patients with retinal vein occlusion (RVO).
Methods: A comprehensive search of the PubMed, Embase, and Ovid databases was conducted to identify studies comparing OCTA metrics among RVO, RVO-fellow, and control eyes. Outcomes of interest included parameters related to foveal avascular zone (FAZ) and fovea- and optic nerve head (ONH)-centered perfusion measurements of superficial capillary plexus (SCP), deep capillary plexus (DCP), and choriocapillaris layer.

Purpose: To investigate sensitivity of contributing factors to heterogeneity corrections in ocular brachytherapy using iodine-125 (I) Collaborative Ocular Melanoma Study (COMS) plaques.
Material And Methods: Using egs_brachy, Monte Carlo (MC) simulations were performed for I COMS plaques (model: IsoAid IAI-125A). Homogeneous dose (D) was estimated under the American Association of Physicists in Medicine Task Group-43 assumptions, with 85 Gy prescribed to a 5 mm depth.
