Abstract
Summary Various authors have tried to determine visual acuity both electrophysiologically (Sokol, 1976 and 1978; Marg et al., 1976; Maffei and Fiorentini, 1977) and with psychophysical methods (Teller et al., 1974; Banks and Salapatek, 1976; Atkinson et al., 1976) in awake children. Our experiments try to verify the possibility of assessing visual acuity in children under Ethrane anesthesia. We conclude that under Ethrane anesthesia VEPs produced by phase-alternating square-wave gratings do not allow a fine assesment of visual acuity. Gross indications of visual acuity can however be obtained.Keywords
