A patient in their late 60s was found to have a subfoveal hypopigmented tortuous lesion potentially resembling a nematode (Figure, A). Presenting visual acuity was 20/40. Indocyanine green angiography demonstrated hyperfluorescence, confirming the choroidal etiology of the pseudo-nematode pattern (Figure, B). Optical coherence tomography showed an enlarged shallow choroidal vessel causing elevation and mild disruption of the overlying retinal pigment epithelium. Serial imaging did not demonstrate any progression. Though the image appears to resemble the findings of a retinal nematode, a vision-threatening pathology, multimodality imaging confirms a benign anatomical variation.¹

一名 60 多岁的患者被发现有一个中心凹下色素减退的曲折病变，可能类似于线虫（图 A）。呈现视力为 20/40。吲哚菁绿血管造影显示高荧光，证实了假线虫模式的脉络膜病因（图 B）。光学相干断层扫描显示扩大的浅脉络膜血管导致上覆视网膜色素上皮升高和轻度破坏。连续成像没有显示任何进展。虽然图像看起来类似于视网膜线虫的发现，这是一种威胁视力的病理学，但多模态成像证实了良性解剖变异。¹
