Lightweight Retinal Layer Segmentation With Global Reasoning.
IEEE Trans Instrum Meas
May 2024
School of Mechanical Engineering, Shandong University, Jinan 250061, Shandong, China.
Automatic retinal layer segmentation with medical images, such as optical coherence tomography (OCT) images, serves as an important tool for diagnosing ophthalmic diseases. However, it is challenging to achieve accurate segmentation due to low contrast and blood flow noises presented in the images. In addition, the algorithm should be light-weight to be deployed for practical clinical applications.

Clin Ophthalmol
January 2025
University Eye Clinic Maastricht, Maastricht, the Netherlands.
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.

Department of Ophthalmology, Copenhagen University Hospital - Rigshospitalet, Glostrup, Denmark.
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.

January 2025
Ningbo Eye Hospital, Wenzhou Medical University, Ningbo, Zhejiang, 315000, P.R. China. Electronic address:
Purpose: To evaluate the differences in fundus tessellation among various severities using multifocal visual electrophysiology (MfERG) and optical coherence tomography angiography (OCTA) for clinical grading and treatment.
Methods: This study included 52 patients totaling 87 eyes. The Early Treatment Diabetic Retinopathy Study (ETDRS) grid division method was utilized to assess Grade of fundus tessellation.
Severity grading of hypertensive retinopathy using hybrid deep learning architecture.

Regional Institute of Ophthalmology, Indira Gandhi Institute of Medical Sciences, Patna, 800025, Bihar, India.
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.
