High-Resolution Imaging of Patients with Bietti Crystalline Dystrophy with CYP4V2 Mutation
Multifocal ERGs (mfERGs) of BCD patients. Topographic map and local responses of multifocal ERGs recorded from Case 1 ((a), (b)), Case 2 ((c), (d)), and Case 3 ((e), (f)) are shown. Results from right eyes ((a), (c), and (e)) and left eyes ((b), (d), and (f)) are shown. The amplitudes of the mfERGs in the foveal area are severely reduced in all cases.
