[ERG and EOG results in X-chromosomal vitreo-retinal degeneration (author transl)].

ERG and EOG were performed in three male patients deriving from two no related families and who had vitreo-retinal degeneration including macula area. The EOG was below normal and ERG-potentials particularly b-waves reduced. The finding although of interest are not pathognomically significant. Therefore the diagnosis is only proven by morphological fundus changes and genetics studies indicating a sex-linked transmission.
