Al-Shifa J Ophthalmol Jan ;13(2):93-9.

This cross-sectional study was conducted to assess the frequency of various refractive errors in intellectually disabled population in a special school. Forty children were enrolled in this study. Auto refraction, visual acuity, objective refraction, and subjective refraction were done. The level of intellectual disability was divided into mild (IQ 50-69), moderate (IQ 35-49), severe (IQ <34). The frequency of various refractive errors was estimated as well as presence of any significant relationship between level of intellectual disability and refractive errors.
