Widefield Swept-source OCT Angiography Metrics Associated with the Development of Diabetic Vitreous Hemorrhage A Prospective Study
Objective: To investigate the association among widefield swept-source optical coherence tomography angiography (WF SS-OCTA) metrics and systemic parameters and the occurrence of vitreous hemorrhage (VH) in eyes with proliferative diabetic retinopathy (PDR). Design: Prospective, observational study. Participants: Fifty-five eyes from 45 adults with PDR, with no history of VH, followed for at least 3 months. Methods: All patients were imaged with WF SS-OCTA (Montage 15×15mm and HD-51 Line scan). Images were independently evaluated by two graders for quantitative and qualitative WF SS-OCTA metrics defined a priori. Systemic and ocular parameters and WF SS-OCTA metrics were screened using Least Absolute ...
