Case Report: Herein, a case of an unusual ocular presentation of primary antiphospholipid syndrome. The patient disclosed localized retinal ischemia due to branch retinal artery occlusion, confirmed by fluorescein angiography and manual perimetry.
Comments: The ocular manifestation led to the diagnosis and successful treatment of the systemic disease.

Introduction: Brain ischemia-reperfusion can cause serious and irreversible health problems. Recent studies have suggested that certain flavonoids may help stabilize the correctly folded structure of the visual photoreceptor protein rhodopsin and offset the deleterious effect of retinitis pigmentosa mutations.
Objective: The current study aimed to determine the effect of 3',4'-Dihydroxyflavonol (DiOHF) supplementation for 1 week on lipid peroxidation in the retina tissue following focal brain ischemia-reperfusion in rats.

Background And Objectives: Hypertensive Retinopathy (HR) is a retinal manifestation resulting from persistently elevated blood pressure. Severity grading of HR is essential for patient risk stratification, effective management, progression monitoring, timely intervention, and minimizing the risk of vision impairment. Computer-aided diagnosis and artificial intelligence (AI) systems play vital roles in the diagnosis and grading of HR.

One in 16, 000 live births is affected by the retinal tumor RB (retinoblastoma), which is frequently found in a child's early years. Both of the RB1 alleles that have been locally mutated in the affected retina are present in 60 percent of cases. Retinoblastoma (RB) can be detected using a variety of techniques, including imaging of the brain and orbits, eye examinations under anesthesia (EUAs), and the discovery of cell-free tumor DNA in samples of aqueous humor or plasma.

: This study aimed to evaluate the location of retinal fractal dimension (FD) abnormalities in individuals with diabetes mellitus (DM) and hypertension (HTN) without retinopathy. The annular zone of 6 mm × 6 mm OCTA images centered on the fovea was partitioned into thin annuli and analyzed using fractal analysis to measure FDs. The cohort ( = 114) had an average age of 55.

: Accurate target definition, treatment planning and delivery increases local tumor control for radiotherapy by minimizing collateral damage. To achieve this goal for uveal melanoma (UM), tantalum fiducial markers (TFMs) were previously introduced in proton and photon beam radiotherapy. However, TFMs cause pronounced scattering effects in imaging that make the delineation of small tumors difficult.
