The Standing Potential of the Eye in Vascular and Degenerative Disease of the Retina

The changes which occur in the standing potential of the eye when retinal illumination is altered were observed by means of the EOG technique. A detailed description is given of some typical fundus diseases of the eye such as closure of the central retinal artery, closure of the central retinal vein, diabetic retinopathy, retinal detachment, choroiditis, and pigmentary degeneration, and results obtained by this methods were compared with the ERG. From these observations following two suggestion are given. 1) Tho light rise of the standing potential is influenced not only by the layers supplied by the choroidal blood but also by the layers supplied ny the central retinal artery. The light rise may be generated in the pigment epithelium or receptor cells layers, however, it could be also connected with the function of the inner nuclear layer. 2) The base-value and the dark trough of the standing potential depend on the outer layers of the retina.
