[ERG- and EOG results in the vitreo-retinal syndrom of Jaffe (author's transl)].

An ERG and EOG were performed in 2 cases of Jaffe's vitreo-retinal traction syndrom with differing stages of the disease. In the first stage of the disease there was a crease in the b-waves in the presence of a normal EOG. In stage II there was a beginning leveling of the ERG with gradual disappearance of the x-waves and b1-waves in the presence of the subnormal EOG. In stage III, there was a clear discrepancy between the monophasic ERG with deep a-wave and smooth b-waves, and the subnormal EOG, thus indicating damage to the retinal vascular system which is important for the nutrition of the III neurons.
