: To study the role of Optical coherence tomography (OCT) Angiography (OCTA) in detecting retinal vascular and macular abnormalities as compared to Fundus Fluorescein Angiography (FFA) in subjects with Asteroid hyalosis (AH).: In a prospective study, patients with AH underwent OCTA and FFA. AH graded as Grade 1 in 8 (optic disc, second order vessels visible), Grade 2 in 4 (optic disc, first-order vessels visible), Grade 3 in 11 (hazy view of optic disc) and Grade 4 (no view of fundus) in 2 eyes.: A total of 20 patients (25 eyes) with AH were included. In comparison to FFA, OCTA was able to similarly detect Diabetic Retinopathy changes such as Neovascularization, microaneurysms, capillary dropout, and foveal avascular zone extent in vascular occlusion in all grades of AH.: OCTA, a noninvasive imaging tool, could detect various retinal vascular and macular abnormalities in patients with all grades of AH in comparison to FFA.
研究在患有星状玻璃体病变（AH）的受试者中，光学相干断层扫描血管造影（OCTA）与眼底荧光血管造影（FFA）相比在检测视网膜血管和黄斑异常方面的作用。：在一项前瞻性研究中，AH患者接受了OCTA和FFA检查。AH分级为1级的有8只眼（视盘、二级血管可见），2级的有4只眼（视盘、一级血管可见），3级的有11只眼（视盘模糊），4级（眼底不可见）的有2只眼。：总共纳入了20例AH患者（25只眼）。与FFA相比，OCTA能够同样检测出AH各分级中糖尿病视网膜病变的变化，如新生血管形成、微动脉瘤、毛细血管缺失以及血管闭塞时黄斑无血管区范围。：OCTA作为一种非侵入性成像工具，与FFA相比，能够检测出所有分级AH患者的各种视网膜血管和黄斑异常。
