High-Resolution Imaging of Patients with Bietti Crystalline Dystrophy with CYP4V2 Mutation

Figure 3

Full-field electroretinograms (ERGs) recorded according to the ISCEV standard protocol in a normal control and BCD patients. Dark-adapted 0.01 (rod), dark-adapted 3.0 (mixed rod-cone), light-adapted 3.0 (cone), and light-adapted 3.0 flicker (30-Hz flicker) ERGs are shown. The rod, mixed rod-cone, cone, and 30-Hz flicker ERGs were nonrecordable in Patients 1 and 2. The rod and the combined rod-cone b-waves of the full-field ERGs were slightly reduced in the left eye of Patient 3. The amplitudes of the b-wave of the cone responses and the amplitude of the flicker responses in Patient 3 were within normal limits.
