EOG and ERG Components in Ischemic Retinopathy

Abstract
In 12 adult subjects with ischemic retinopathy and in 2 children with surgically dissected retinal artery EOG light peaks and dark troughs were recorded. Standing potentials, light-induced potentials and dark troughs were reduced significantly in all affected eyes. Standing potential, light-induced oscillation and dark oscillation do not only depend upon the pigment epithelium/receptor unit; the integrity of the inner retinal structures is also of significance. The analysis of slow EOG components alone does not allow to localize and determine the level of retinal defects.
