Stage-dependent choriocapillaris impairment in Best vitelliform macular dystrophy characterized by optical coherence tomography angiography.

ABSTRACT: Characterization of vascular impairment in Best vitelliform macular dystrophy (BVMD) is essential for the development of treatment modalities and therapy trials. As such, we seek to characterize the choriocapillaris (CC) at each stage of the disease process in 22 patients (44 eyes) with a diagnosis of BVMD confirmed by genetic sequencing. We utilize optical coherence tomography angiography (OCTA) images to characterize the CC and correlate our findings to the status of the retinal pigment epithelium (RPE) as observed on short-wavelength fundus autofluorescence (SW-AF) images. We observed that in the vitelliruptive stage, the CC appeared as bright and granular in the area where the vitelliform lesion was present. In the atrophic stage, varying degrees of CC atrophy were observed within the
