Information
Fig1: Wide field scan ruled out the existence of non-perfusion area (NPA) in peripheral region. Zoomed in observation confirmed the abnormity of foveal avascular zone (FAZ). Quantification value showed extensive enlargement of FAZ area and perimeter, poor circularity and low 300um ring blood flow density.
Fig2: Fundus fluorescein angiography (FFA) at 1′56″ found one leaking spot (red circle) in macula, it was difficult to tell whether it’s NVE. OCTA confirmed it was just a microaneurysm in deep capillary complex (DVC) layer.
Fig3: Structural enface of outer retina suggested there was some area being missed after first focal laser photocoagulation (blue circle) for NPA. Then confirmed effective laser spots after the supplemental application (red circle).
OCT and OCTA were one-shot captured by a 400KHz SSOCT system (BMizar, BM-400K, TowardPi Medical, Beijing, China). It plays an important role in not only diagnosis but also guidance of treatment.
