Explainable deep learning self‐supervised vision transformer for fundus‐based myopia classification

Acta Ophthalmologica, EarlyView.
Abstract Purpose To develop and validate a self‐supervised vision transformer (ViT) for automated three‐class classification of Normal, High Myopia (HM), and Pathologic Myopia (PM) from colour fundus photographs, with anatomically faithful interpretability. Methods A DINOv2 self‐supervised ViT was fine‐tuned using a two‐stage transfer‐learning protocol

Longitudinal progression of retinal nonperfusion in clinically stable diabetic retinopathy

Acta Ophthalmologica, EarlyView.
Abstract Purpose To longitudinally assess and quantify changes in retinal nonperfusion (NP) in clinically stable diabetic retinopathy (DR) using ultra‐widefield fluorescein angiography (UWF‐FA) and optical coherence tomography angiography (OCTA). Methods Fifty‐one eyes from thirty‐three patients were followed for a mean of 15.9 ± 11.4 months.
