Purpose: Valvular heart disease (VHD) contributes significantly to cardiovascular-related morbidity worldwide. Aortic valve stenosis is the third most common cardiovascular disease in the Western world, after hypertension and coronary artery disease. Recent studies have reported an association between VHD and the presence of subretinal drusenoid deposits (SDDs), a distinct manifestation of age-related macular degeneration (AMD).

Purpose: Macular edema is a known complication following complicated retinal detachment repair with silicone oil (SiO) tamponade. Limited previous research has not led to a consensus regarding the safety and efficacy of intra-SiO injections. Consequently, we aim to present our case series study on intra-SiO injections for postoperative macular edema.

Methods: GA findings on FAF and OCT were semi-automatically annotated at a single time point in 36 pairs of FAF and OCT scans obtained from 36 eyes in 24 patients with dry age-related macular degeneration (AMD). The GA area, focality, perimeter, circularity, minimum and maximum Feret diameter, and minimum distance from the center were compared between FAF and OCT annotations.
: To design a novel anomaly detection and localization approach using artificial intelligence methods using optical coherence tomography (OCT) scans for retinal diseases. : High-resolution OCT scans from the publicly available Kaggle dataset and a local dataset were used by four state-of-the-art self-supervised frameworks. The backbone model of all the frameworks was a pre-trained convolutional neural network (CNN), which enabled the extraction of meaningful features from OCT images.

: Visual acuity (VA) assessments are crucial in ophthalmology but traditionally rely on in-clinic evaluations. The emergence of telemedicine has spurred interest in creating dependable self-administered VA tests for use beyond standard clinical environments. This study evaluated the practicality and validity of a self-administered near VA card test against traditional Snellen and Rosenbaum Pocket Vision Screener (RPVS) methods for home monitoring and enhancing clinical workflow.

Objective: To develop an automated method for efficiently downloading a large number of optical coherence tomography (OCT) scans obtained using the Heidelberg Spectralis (Heidelberg Engineering, Heidelberg, Germany) platform.
Methods: The electronic medical records and OCT scans were extracted for all patients with age-related macular degeneration treated at the Hadassah University Hospital Retina Clinic between 2010 and 2021. A macro was created using Visual Basic for Applications (VBA) and Microsoft Excel to automate the export process and anonymize the OCT scans in accordance with hospital policy.
Aim: The primary aim was to evaluate the use of optical coherence tomography angiography (OCTA) versus fluorescein angiography (FA) for detecting and monitoring retinal neovascularization (NV) in patients with proliferative diabetic retinopathy (PDR) receiving treatment with anti-vascular endothelial growth factor (anti-VEGF).
Methods: Treatment-naïve patients with PDR, willing to begin anti-VEGF treatment without laser from 9/2018-2/2020 were included. FA and OCTA scans were obtained at baseline, and a second OCTA scan was performed after 6 months of anti-VEGF therapy.

Purpose: The main objective of the study is to investigate the prevalence of anxiety in patients with neovascular age-related macular degeneration (nAMD).
Methods: A retrospective cross-sectional study of 3 304 nAMD patients and 16 515 age- and gender-matched controls. The proportions of patients with anxiety were compared between the groups using univariate analyses and a multivariate logistic regression model.
Objective: To present a fluorescein angiography (FA)‒based computer algorithm for quantifying retinal blood flow, perfusion, and permeability, in patients with diabetic retinopathy (DR). Secondary objectives were to quantitatively assess treatment efficacy following panretinal photocoagulation (PRP) and define thresholds for pathology based on a new retinovascular function (RVF) score for quantifying disease severity.
Methods: FA images of 65 subjects (58 patients and 7 healthy volunteers) were included.

Purpose: To analyze the genotype-phenotype correlation in patients with retinitis pigmentosa (RP) caused by mutations in the FAM161A, DHDDS, or MAK genes using ultra-widefield fundus autofluorescence (UWF-FAF) imaging.
Methods: Retrospective case series of patients with autosomal recessive RP (ARRP) with confirmed causative genetic mutations and available UWF-FAF imaging data. The UWF-FAF data were graded in a blinded fashion using the following criteria: the pattern of macular abnormalities on FAF, the presence or absence of horizontal linear hyperautofluorescence, the extent of decreased autofluorescence (DAF), the shape of DAF, and the presence of hyperautofluorescence at the optic disk.
