A 60-year-old man presented with deterioration of vision in his right eye. Funduscopic examination showed bilateral optic disc swelling. Ultrasonography revealed optic disc drusen. Optic neuropathy due to optic disc drusen can cause transient and permanent visual impairment.

Purpose: This study aims to explore the diagnostic utility of ultrasound B-scan while introducing the "Triangle" sign as a novel indicator. It also validates the sign's efficacy in distinguishing between choroidal detachment (CD) and suprachoroidal hemorrhage (SCH) from retinal detachment (RD) and vitreous hemorrhage (VH).
Patients And Methods: Retrospective analysis of consecutive cases of total CD and SCH undergoing B-scan at a single tertiary imaging center.

Background: Glaucoma, particularly open-angle glaucoma (OAG), is a leading cause of irreversible blindness, associated with optic nerve damage, retinal ganglion cell death, and visual field defects. Corneal biomechanical properties and cellular components, such as corneal nerve and keratocyte densities assessed by in vivo confocal microscopy (IVCM), may serve as biomarkers for glaucoma progression. This study aimed to explore the relationship between corneal nerve parameters, keratocyte density, and optical coherence tomography (OCT)-derived retinal nerve fiber layer (RNFL) thickness in primary open-angle glaucoma (POAG) patients and controls.

Purpose: Retinopathy of prematurity (ROP) stage is defined by the visual appearance of the vascular-avascular border, which reflects a spectrum of pathologic neurovascular tissue (NVT). Previous work demonstrated that the thickness of the ridge lesion, measured using OCT, corresponds to higher clinical diagnosis of stage. This study evaluates whether the volume of anomalous NVT (ANVTV), defined as abnormal tissue protruding from the regular contour of the retina, can be measured automatically using deep learning to develop quantitative OCT-based biomarkers in ROP.

Introduction: Optic disc drusen (ODD) are believed to have a genetic predisposition, with autosomal dominant inheritance pattern with incomplete penetrance suggested through family pedigree analysis. ODD prevalence is higher in certain genetic disorders, such as pseudoxanthoma elasticum and retinitis pigmentosa. This study aimed to identify candidate genes potentially involved in the development of ODD.

Purpose: To determine whether imaging features derived from fundus photographs contain 3D eye shape information beyond that available from spherical equivalent refraction (SER).
Methods: We analysed 99 eyes of 68 normal adults in the UK Biobank. An ellipsoid was fitted to the entire volume of each posterior eye (vitreous chamber without the lens)-segmented from magnetic resonance imaging of the brain.
