Abstract

Purpose: To report the clinical course and optical coherence tomography (OCT) findings of ocular angiostrongyliasis.

Methods: 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.

Results: The patient was administered oral and topical prednisolone. The roundworm, identified as Angiostrongylus cantonensis, 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.

Conclusion: This case report describes an infrequent presentation and illustrates the clinical course and OCT findings of ocular angiostrongyliasis.

眼血管圆线虫病的临床过程及光学相干断层扫描1例报告。

目的:报道眼血管圆筒形线虫病的临床病程和光学相干断层扫描(OCT)表现。方法:女性，36岁，进食普通生淡水虾及其他生食物，右眼急性单侧无痛性视力丧失。她的右眼最佳矫正视力(BCVA)为食指1英尺。眼底检查显示玻璃体炎，全身性视网膜色素上皮改变，玻璃体6点钟位置有移动的蛔虫。右眼黄斑OCT示视网膜变薄，外限制膜及椭球带缺失，视网膜下超反射物质团块，浅层脉络膜超反射灶。结果:患者口服和外用强的松龙。采用23G巩膜切割和玻璃体平面部切割，从玻璃体中完全取出蛔虫，鉴定为广州管圆线虫。最后的BCVA位于食指1英尺处。结论:本病例报告描述了一种罕见的眼部血管线虫病的临床表现和OCT表现。
