Tang F, et al. - In patients with diabetes, researchers sought for the correlation of best-corrected visual acuity (BCVA) with intercapillary area (ICA) measured from optical coherence tomography angiography (OCT-A). They also performed a comparison of the strength of associations between BCVA with ICA and other OCT-A metrics. Findings suggested an independent association of increased ICA measured from OCT-A, describing enlargement of capillary rarefaction or closure at macular area, with BCVA. This indicates ICA to be a potential marker to quantify retinal microvascular abnormalities relating to vision among individuals with diabetes.
