PURPOSE
Optical coherence tomography angiography (OCTA) can visualize the vascular status of the choriocapillaris noninvasively and separately from the other vascular beds. We describe focal ischemia in the choriocapillaris and reperfusion of the area in hypertensive choroidopathy using en-face OCTA.
CASE
A 32-year-old woman diagnosed with pregnancy-induced hypertension presented with acute anorthopia in the right eye after delivery via Caesarian section. Fundus examination showed an Elschnig's spot and serous retinal detachment (SRD) in the inferior perifoveal region. Early-phase fluorescein angiography and indocyanine green angiography images showed focally delayed choroidal perfusion, i.e., regional absence of choroidal flush. OCTA also showed a focal dark area in a slab of the choriocapillaris corresponding to the angiographic observation. After oral antihypertensive treatment, the dark area on the OCTA image of the choriocapillaris resolved over time in association with the resolving SRD.
CONCLUSION
En-face OCTA is a useful technology to follow noninvasively the circulatory status of the choriocapillaris in hypertensive choroidopathy.
目的
光学相干断层扫描血管造影（OCTA）能够无创地显示脉络膜毛细血管的血管状态，且可与其他血管床区分开来。我们使用表面 OCTA 描述高血压性脉络膜病变中脉络膜毛细血管的局灶性缺血及该区域的再灌注情况。
病例
一名 32 岁被诊断为妊娠高血压的女性，剖宫产术后右眼出现急性斜视。眼底检查显示在黄斑中心凹下方区域有 Elschnig 斑和浆液性视网膜脱离（SRD）。早期荧光素血管造影和吲哚菁绿血管造影图像显示脉络膜灌注局部延迟，即局部脉络膜充盈缺失。OCTA 也显示在脉络膜毛细血管层有一个与血管造影观察结果相对应的局灶性暗区。口服抗高血压治疗后，随着 SRD 的消退，脉络膜毛细血管 OCTA 图像上的暗区随时间逐渐消失。
结论
表面 OCTA 是一种用于无创跟踪高血压性脉络膜病变中脉络膜毛细血管循环状态的有用技术。
