• In the study of 50 patients with unilateral central retinal vein occlusion, abnormal electroretinograms were observed in the fellow eyes of 18 patients (36%). The abnormal electroretinograms were super-normal in 15 patients (30%) and negative (+) in the fellow eyes of 3 patients (6%). The amplitudes of a and b waves were significantly greater in the fellow eye than those in normal controls. During a 1- to 9-year follow-up, central retinal vein occlusion developed in three fellow eyes (6%). The abnormal electroretinograms in the fellow eyes reflected such factors as circulatory disturbance of the retina that might have led to central retinal vein occlusion in the affected eye.
