Visual functions (grating acuity, visual field size, optokinetic nystagmus and eye alignment) were tested as part of a longitudinal study in 96 low‐birth‐weight infants (birth weight 1500–2500 g) at one year of corrected age. Except for optokinetic nystagmus, deficit rates of all visual functions were low, and the obtained values comparable with normal age values in full‐term infants. Effects of gestational duration, birth weight and intrauterine growth retardation on visual functions could not be demonstrated. Some perinatal risk factors (mechanical ventilation, oxygen treatment for more than one day, the presence of maternal hypertensive disorders) and a less‐optimal neurodevelopmental status at one year had a negligible effect on visual field size. The observed deficits are not likely to cause disability. Low‐birth‐weight infants appeared not to be at risk for developing visual deficits at one year of corrected age.
