    Negative Vessel Remodeling in Stargardt Disease Quantified with Volume-Rendered Optical Coherence Tomography Angiography

    Purpose: To quantify retinal vasculature changes in Stargardt disease1 with volume-rendered optical coherence tomography angiography (OCTA). Methods: OCTA volumes from heathy subjects and two subgroups of STGD1 patients with the presence/absence of definitely decreased autofluorescence (DDAF) areas were compared. OCTA vessel surface area (VSA) and vessel volume (VV) were measured in central zones (Z) of 1, 2 and 3mm diameter. Results: 29 eyes of 15 STGD1 patients (20/9 eyes with/without DDAF) and 30 eyes of 15 controls contributed data. An enlarged foveal avascular zone was found in STGD1 patients without and even more with DDAF associated with ...
