Children with intellectual disabilities have an increased risk of visual impairment, caused by both ocular and cerebral abnormalities, but this risk has not been quantified. The same applies to preterm children and children with cerebral palsy with a normal intelligence. Many cases probably go unidentified, because participation of these children…

Low vision children (ages 4-19, n=137) were screened, and 77 percent were advised to have comprehensive clinical evaluations or ophthalmology services. The visual capability of the referred children was determined, low vision aids were prescribed for 56 children, and the degree of successful utilization of aids was evaluated. (JDD)

Threshold luminance necessary to evoke an eye movement was evaluated as a function of age (6-21 years) and visual angle (6-42 degrees from the fovea). (BRT)

National estimates based on the findings from the Health Examination Survey in 1963 to 1965 of uncorrected monocular and binocular visual-acuity levels of children were studied. A nationwide sample of 7,417 children was selected to represent the approximately 24 million noninstitutionalized American children between ages 6 and 11 years. Testing…
