To report the clinical course and optical coherence tomography (OCT) findings of ocular angiostrongyliasis.
A 36-year-old female with a history of ingesting regular raw freshwater shrimp and other raw food presented with acute unilateral painless visual loss in the right eye. Her right eye's best-corrected visual acuity (BCVA) was 1 ft of the count finger. Fundus examination showed vitritis, generalized retinal pigment epithelial alteration, and a moving roundworm in the vitreous at the 6 o'clock position. Macular OCT of her right eye showed thinning of the retina, loss of the external limiting membrane and ellipsoid zone, subretinal hyper-reflective material clumping, and hyper-reflective foci at the superficial choroidal layer.
The patient was administered oral and topical prednisolone. The roundworm, identified as , was wholly extracted from the vitreous using a 23G sclerotomy port and pars plana vitrectomy. The final BCVA was 1 ft of the count finger.
This case report describes an infrequent presentation and illustrates the clinical course and OCT findings of ocular angiostrongyliasis.
报告眼部血管圆线虫病的临床病程及光学相干断层扫描（OCT）检查结果。
一名36岁女性，有食用普通生淡水虾及其他生食史，右眼突发急性单侧无痛性视力丧失。其右眼最佳矫正视力（BCVA）为眼前1英尺数指。眼底检查显示玻璃体炎、视网膜色素上皮广泛改变，以及在6点钟方位玻璃体中有一条活动的蛔虫。其右眼黄斑OCT显示视网膜变薄、外界膜和椭圆体带缺失、视网膜下高反射物质聚集，以及脉络膜浅层有高反射灶。
给予患者口服及局部使用泼尼松龙。通过23G巩膜切开端口及玻璃体平坦部玻璃体切除术从玻璃体中完整取出了鉴定为[此处原文缺失蛔虫具体名称]的蛔虫。最终BCVA为眼前1英尺数指。
本病例报告描述了一种罕见的表现，并阐述了眼部血管圆线虫病的临床病程及OCT检查结果。
