Retin Cases Brief Rep
December 2024
Department of Ophthalmology and Visual Neurosciences, University of Minnesota, Minneapolis, MN, USA.
Purpose: To report the clinical presentation, treatment course, and outcome of a case of bilateral frosted branch angiitis (FBA) and neuroretinitis associated with acute Epstein-Barr virus (EBV) infection in a pediatric patient with Turner Syndrome.
Methods: Case report with multimodal ocular imaging and extensive systemic workup.
Results: A 16-year-old female with Turner syndrome presented with acute bilateral vision loss, hearing loss, and ataxia.

Optical Coherence Tomography (OCT) offers high-resolution images of the eye's fundus. This enables thorough analysis of retinal health by doctors, providing a solid basis for diagnosis and treatment. With the development of deep learning, deep learning-based methods are becoming more popular for fundus OCT image segmentation.

Alzheimers Dement
December 2024
Department of Neurosurgery, Maxine Dunitz Neurosurgical Research Institute, Cedars-Sinai Medical Center, Los Angeles, CA, USA.
Background: This study identifies and quantifies diverse pathological tau forms in the retina at both early and advanced stages of Alzheimer's disease (AD) and assesses their correlation with disease status. In the pathogenesis of AD, the tau protein undergoes post-translational modifications, including hyperphosphorylation (p-tau). As the disease progresses, pathological tau can propagate as oligomers, aggregate into fibrils, and paired helical filaments (PHF), and ultimately form intraneuronal neurofibrillary tangles (NFTs).

School of Computed and Augmented Intelligence, Arizona State University, Tempe, AZ.
Objective: To report the development and performance of 2 distinct deep learning models trained exclusively on retinal color fundus photographs to classify Alzheimer disease (AD).
Patients And Methods: Two independent datasets (UK Biobank and our tertiary academic institution) of good-quality retinal photographs derived from patients with AD and controls were used to build 2 deep learning models, between April 1, 2021, and January 30, 2024. ADVAS is a U-Net-based architecture that uses retinal vessel segmentation.
Perivascular Chorioretinal Atrophy: an Unusual Feature in Pathologic Myopia Eyes.
Am J Ophthalmol
December 2024
Department of Ophthalmology, New Civil Hospital, Strasbourg University Hospital, FMTS, Strasbourg, France. Electronic address:
Purpose: To describe a new feature in pathologic myopia: perivascular patchy chorioretinal atrophy (PVCA) DESIGN: Cross-sectional study METHODS: 604 eyes of 312 highly myopic patients followed at Strasbourg University Hospitals were reviewed for the presence of PVCA lesions. Demographic, clinical, and paraclinical data (ultra-widefield retinography, optical coherence tomography (OCT), fluorescein and indocyanine green angiography images) were analyzed. Controls were matched for age, sex, and axial length (AL).
