A 65-year-old man with diabetes and a history of fever of unknown origin 2 weeks earlier complained of sudden decreased vision in the left eye. The patient was diagnosed with bilateral West Nile virus (WNV) chorioretinitis associated with occlusive retinal vasculitis in the left eye. Swept-source optical coherence tomography angiography (SS-OCTA) of the left eye showed extensive, well-delineated, hypointense non-perfusion areas and perifoveal capillary arcade disruption in the superficial capillary plexus, as well as larger non-perfusion areas, capillary rarefaction, and diffuse capillary network attenuation and disorganization in the deep capillary plexus. OCTA may be a valuable tool for noninvasively assessing occlusive retinal vasculitis associated with WNV infection. It allows an accurate detection and precise delineation of areas of retinal capillary nonperfusion in both the superficial and deep capillary plexuses.

一名65岁男性，患有糖尿病，2周前有不明原因发热病史，主诉左眼视力突然下降。该患者被诊断为双侧西尼罗河病毒（WNV）脉络膜视网膜炎，左眼伴有闭塞性视网膜血管炎。左眼扫频光学相干断层扫描血管造影（SS-OCTA）显示，浅层毛细血管丛有广泛、界限清晰的低信号无灌注区和黄斑中心凹周围毛细血管拱环破坏，深层毛细血管丛有更大的无灌注区、毛细血管稀疏以及弥漫性毛细血管网衰减和紊乱。OCTA可能是一种用于无创评估与WNV感染相关的闭塞性视网膜血管炎的有价值工具。它能够准确检测和精确描绘浅层和深层毛细血管丛中视网膜毛细血管无灌注区域。[《眼科手术、激光与视网膜成像》。2017年；48:672 - 675。]
