Reperfusion of the choriocapillaris observed using optical coherence tomography angiography in hypertensive choroidopathy

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.
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.
En-face OCTA is a useful technology to follow noninvasively the circulatory status of the choriocapillaris in hypertensive choroidopathy.
