Abstract:
We carried out five common electroretinographies according to the recommendation by the International Society of Clinical Electrophysiology of Vision in the eyes of 40 non-diabetic brach retinal vein occulusion. The clear media, no previous history of photocoagulation and no evidence of neovascularization of the retina and/or iris were criteria for inclusion in this study. The data were compared with those of fellow eyes, expecting that this procedure may provide a new feature that could have some clinical significance. The reduction of the summed amplitude of oscillatory potentials, and the timing delay of the cone response b-wave and 30Hz flicker responses were of most frequent occurrence. hence, the reduction of the summed amplitude of oscillatory potentials and the timing delay of the cone response b-wave and 30Hz flicker responses may be valuable indicators. These abnormalities represent overall inner retinal dysfunction. The cone response b-wave timing was more frequently affected than that of the maximal combined response b-wave. This fact may reflect that an ischemic lesion is located in the vicinity of the posterior pole of the fundus.
