We examined electroretinogram (ERG) and electrooculogram (EOG) in 14 patients of acute retinal necrosis syndrome. Eyes with retinal detach-ment showed low amplitudes in a and b waves in ERG. The base value of EOG was extremely reduced compared with other uveitis eyes. These findings seemed to indicate that the retinal necrosisinvolved retinal and choroidal vascular occlusions in addition to direct viral infection. Above patho-logical ERG and EOG findings hardly recovered, suggesting the irreversibility of retinal and cho-roidal lesions. The ERG and EOG findings were thus of value in evaluating the prognosis and in determining the timing of surgical intervention including prophylactic vitrectomy in this syndrome.
