Abstract. We reviewed ocular findings in 103 mentally retarded children seen during the past 62 months. Cases of Down syndrome were excluded from the series. They were first seen by us at the age of 11 months through 12 years,average 4 years 10 months. Mental retardation was due to chromosome anomaly 11 cases,cerebral palsy 8 cases,others 18 cases,and unknown 66 cases. When examined under cycloplegia,17.5% had hyperopia over+4 diopters,9.7% had myopia over-4 diopters,and 49.5% had astigmatism over 2 diopters,of which 90.6% had with-the-rule astigmatism. Anisometropia was present in 16 cases(15.5%). Spectacles were needed in 77 cases(74.8%). Horizontal strabismus was present in 49 cases(47.6%)and vertical strabismus in 21 cases(20.4%). Surgical alignment was needed in 10 cases(20.4%). The findings show a high incidence of refractive errors and strabismus in mentally retarded children. We advocate early treatment while visual functions are amenable to improvement.
