    Concentric Choriocapillaris Flow Deficits in Retinitis Pigmentosa Detected Using Wide-Angle Swept-Source Optical Coherence Tomography Angiography

    Purpose : We investigate whether choriocapillaris deficits can be visualized in patients with retinitis pigmentosa (RP) using wide-angle swept-source optical coherence tomography angiography (OCTA), and whether angiography or structure en face images depict a wider area of residual choriocapillaris. Methods : This cross-sectional study included 43 eyes of 43 consecutive patients with RP with a visual acuity ≥0.1, and 12 healthy eyes of 12 volunteers. Using an OCTA device (PLEX Eite 9000), we obtained angiography and structure en face images in the choriocapillaris. The residual choriocapillaris area in a 12 × 12 mm macular cube was measured manually. Results : In patients with ...
