One hundred twenty-eight patients (most less than 13 years old) with various types of cerebral palsy were examined to assess visual acuity, refractive state, oculomotor functions, sensory fusion, and ocular health. Special procedures for examining these patients are described. Vision or ocular defects were found to be present in 86% of these cerebral palsy patients. Significant refractive errors and strabismus were the most common defects, being present in 50% or more of the patients. Ocular disease was relatively uncommon.
