Abstract: Objective To investigate the incidence and risk factors of optic atrophy in cerebral palsy(CP).MethodsThe clinical dates of 872 children with CP were analyzed retrospectively.ResultsThe incidence of optic atrophy was 17.1% in CP.There was no significant difference among sexes,age and clinical types.Asphyxiation (OR=1.787,95%CI:1.225～2.608) and premature delivery (OR=2.074;95%CI:1.332～3.230) were significantly related to optic atrophy.ConclusionIn children with CP,the incidence of optic atrophy is high.Asphyxiation and premature delivery are risk factors of optic atrophy.Examination of ocular fundus should be considered as one of the routine examinations.
