Figure 4. Multifocal electroretinograms of the right and left eye
A: II:3 at 22 years of age and B: II:2 at 26 years of age. The following abbreviations were used: left eye (LE) and right eye (RE). In contrast to II.3, there is a significant affection of macular function in II:2, again demonstrating intrafamilial variability and showing that retinal degeneration can involve the center, and even at an early stage.
