Figure 4. Multifocal electroretinography results of the two patients, carriers, and controls. A: Trace arrays of patients IV/1 and III/2 with 61 elements. B: Response densities (RDs) and implicit times of multifocal electroretinographs for five eccentric rings in patients (marked red), carriers, and controls. Gray area represents the 95% confidence interval of our control database, the single control line in the center of the gray area represents the average of the set of control patients, while error bars represents ± standard deviation (SD). Response densities (RDs) of patients were decreased in all rings, while carriers’ RDs were within the normal range. Implicit times of patients and carriers were delayed in all rings. The following abbreviations were used: right eye (RE) and left eye (LE).
