We evaluated a choroidal macrovessel using optical coherence tomography angiography (OCTA) and indocyanine green angiography (ICGA).
A 79-year-old female presented with blurred vision in both eyes and metamorphopsia of the left eye. Mild cataract was noted in both eyes. Color fundus photography of the left eye revealed a red-orange tortuous vessel originating from the fovea and running in an inferior-temporal direction. Enhanced-depth imaging OCT revealed a large caliber choroidal vascular shadow and ambiguous line of the photoreceptor and retinal pigment epithelium layers. OCTA demonstrated a serpentine-shaped choroidal vessel. This anomalous vessel was seen by early phase ICGA as a rapidly perfused vessel connected to a vortex vein. We diagnosed this anomalous vessel as a choroidal macrovessel. We identified that cataract induced blurred vision in both eyes and choroidal macrovessel induced metamorphopsia in left eye. She was received cataract surgery for both eyes. The degree of metamorphopsia and the choroidal macrovessel of the left eye remains unchanged after a year of follow-up.
OCTA and ICGA are useful techniques to diagnose choroidal macrovessels.
我们使用光学相干断层扫描血管造影（OCTA）和吲哚菁绿血管造影（ICGA）对脉络膜大血管进行了评估。
一名79岁女性双眼视力模糊，左眼有视物变形。双眼均发现轻度白内障。左眼彩色眼底照相显示一条红橙色迂曲血管，起自黄斑中心凹，沿颞下方向走行。增强深度成像OCT显示大口径脉络膜血管阴影以及感光细胞层和视网膜色素上皮层界限不清。OCTA显示一条蜿蜒状脉络膜血管。这条异常血管在ICGA早期表现为一条快速灌注的血管，与涡静脉相连。我们将这条异常血管诊断为脉络膜大血管。我们确定白内障导致双眼视力模糊，脉络膜大血管导致左眼视物变形。她接受了双眼白内障手术。随访一年后，左眼视物变形程度和脉络膜大血管情况未变。
OCTA和ICGA是诊断脉络膜大血管的有用技术。
