The distribution of refractive errors, astigmatism, anisometropia, visual acuity and organic ophthalmic diseases were determined among 149 Finnish mentally retarded (IQ < 70) children, aged 9–10 years. The case group was classified in 3 categories according to the degree of mental retardation. The control group (n = 100) was selected by random sampling.
