Swept-Source OCT Angiography of Serpiginous Choroiditis

En face analysis of SS-OCTA choriocapillaris flow voids provide a noninvasive method for the detection of lesions in patients with SC. The presence of lesions in the choriocapillaris in the absence of retinal pigment epithelium and outer retinal abnormalities supports the hypothesis that choriocapillaris is the primary site of pathologic features in SC and may be a sensitive early sign of disease activity. We propose a simple grading system of SC lesions based on SS-OCTA and fundus autofluorescence findings. Swept-source OCTA is a promising noninvasive method for monitoring patients with SC.
