Abstract
A random sample of 45 schools served by nine school nurses were selected for study. The visual acuity measurements by these nurses were assessed in the orthoptic department. In each school the premises where the examination was performed were noted, the external illumination falling on the measurement chart measured with a photometer, and the distance between the chart and the child measured. Information on 80 consecutive referrals was obtained from records in the orthoptic department.
