Visual Response of Premature Infants: Use of the Optokinetic Nystagmus to Estimate Visual Development

Visual Response of Premature Infants: Use of the Optokinetic Nystagmus to Estimate Visual... Abstract This is the first report of the estimation of the visual response of premature infants when tested by optokinetic nystagmus. Heretofore, visual acuity has not been determined for infants under the weight of five pounds (2,267.96 gm). All of the infants in this report were premature and less than five pounds in weight.
