Two male patients presented with unilateral blurred vision. A small motile worm was found in the vitreous cavity in both cases. In one case, another dead, disintegrated worm was noted in the inferior portion of the vitreous cavity. On each eye, vitreous surgery was performed and the worm was removed by an aspirator. Both worms were identified as Angiostrongylus cantonensis. Since both patients had no signs of meningitis, lumbar puncture was not done. Long-term follow-up confirmed the benefit and safety of the vitreous surgery. Fluorescein angiography revealed severe pigmentary alteration, probably from inflammation of the choroid and retina due to subretinal migration of the worm prior to access into the vitreous cavity.
两名男性患者出现单侧视力模糊。两例患者的玻璃体腔均发现一条活动的小蠕虫。其中一例,在玻璃体腔下部还发现另一条死亡、已解体的蠕虫。对每只眼睛均进行了玻璃体手术,并用吸引器取出蠕虫。两条蠕虫均被鉴定为广州管圆线虫。由于两名患者均无脑膜炎体征,因此未进行腰椎穿刺。长期随访证实了玻璃体手术的益处和安全性。荧光素血管造影显示严重的色素改变,可能是由于蠕虫在进入玻璃体腔之前视网膜下迁移导致脉络膜和视网膜炎症所致。
