Visual Dysfunction and Cerebral Palsy

A study in Developmental Medicine and Child Neurology reports on visual dysfunction in children with cerebral palsy.  Since 60-70% of children with cerebral palsy have cerebral visual impairment, this study wanted to explore the visual dysfunction further.  One hundred twenty nine patients with cerebral palsy ranging in age from 3 months to 15 years old underwent many neuro-ophthalmological assessments.  The results indicated the following:

"Visual dysfunction in diplegia was characterized mainly by refractive errors (75% of patients), strabismus (90%), abnormal saccadic movements (86%), and reduced visual acuity (82%).

The participants with hemiplegia showed strabismus (71%) and refractive errors (88%); oculomotor involvement was less frequent (59%). This group had the largest percentage of patients with altered visual field (64%).

Children with tetraplegia showed a severe neuro-ophthalmological profile, characterized by ocular abnormalities (98%), oculomotor dysfunction (100%), and reduced visual acuity (98%)".
Therapists, teachers and parents need to be aware that  neuro-ophthalmological disorders are one of the main symptoms in CP.  Therefore, this needs to be assessed early in children and determined how it will effect treatment plans and modifications.
