Twelve patients with macular disease were studied. Mean age at the beginning stages of the disease was 61.75 years. They were examined by biomicroscopy, fluorescein angiography, and electrophysiological tests (ERG, EOG, VEP). No relevant correlation could be found between the routinely administered and evaluated ERG and EOG tests and the clinical stage of the disease. The VEP proved a more sensitive means of evaluating macular function in our patients. The possibility of the VEP's being of prognostic importance is raised.
