[Retinal oscillatory potentials in the study of retinopathy in dialyzed subjects with chronic renal insufficiency].

Oscillatory potentials (OP) were recorded from 24 patients with chronic renal insufficiency undergoing hemodialysis. Nobody had visual disturbances. Abnormal OP were found in 11 (45.8%) patients. Moreover the possible correlations among the abnormal OP and some biochemical and clinical parameters were studied. The Authors emphasize the usefulness of the OP to disclose the subclinical retinopathy of the patients with renal insufficiency.
