PURPOSE

To reveal vascular signals at the choriocapillaris level in central serous chorioretinopathy (CSC) using optical coherence tomographic angiography (OCTA).

PROCEDURES

We analyzed vascular signals at the choriocapillaris level in 58 CSC and 51 contralateral eyes by OCTA (RTVue XR Avanti with AngioVue; Optovue Inc., Fremont, Calif., USA). Data analysis included age, best corrected visual acuity (BCVA), disease duration and serous retinal detachment (SRD) height.

RESULTS

Morphologically, abnormal signals at the choriocapillaris level were detected in all CSC eyes (100%), and then classified into three patterns. Age, BCVA, disease duration and SRD height showed no significant correlation with signal patterns. Thirty-one contralateral eyes (61%) showed abnormal signals at the choriocapillaris level on OCTA, while 20 (39%) had a normal pattern.

CONCLUSIONS

OCTA revealed three types of abnormal signals not only in CSC eyes but also in fellow eyes without SRD. OCTA may provide information for elucidating the underlying pathogenesis of CSC.
