Choriocapillaris flow deficit in Bietti crystalline dystrophy detected using optical coherence tomography angiography

Abstract

Using OCTA, choriocapillaris blood flow deficit could be observed in most patients with BCD with <i>CYP4V2</i> mutations. The presence of the choriocapillaris at the subfovea was significantly correlated with visual function in these patients. Analysis of choriocapillaris blood flow using OCTA allows non-invasive assessment of the patient's state.
