• Electro-oculogram (EOG) measurements were obtained on seven patients with moderately extensive lesions of fundus flavimaculatus. Each patient was tested by two different methods of measuring EOG light-peak to dark-trough ratios. The results show that erroneously low ratios can be observed unless a diffusing sphere is employed in the determination of light-peak to dark-trough ratios in fundus flavimaculatus and presumably other diseases that affect primarily the posterior pole.
