Visual disorders associated with cerebral palsy
Insights
Cerebral palsy (CP) significantly impacts vision in school children, with most experiencing ocular issues like squint and refractive errors. Early ophthalmological assessment is crucial for managing visual impairments in children with CP.
Area of Science:
- Ophthalmology
- Pediatrics
- Neurology
Background:
- Cerebral palsy (CP) is a group of disorders affecting movement and posture, often accompanied by other neurological and developmental challenges.
- Visual impairments are common in children with CP, but their spectrum and frequency in unselected populations require further elucidation.
Purpose of the Study:
- To investigate the prevalence and types of ocular abnormalities in school-aged children with cerebral palsy.
- To emphasize the importance of early and comprehensive ophthalmological assessment for children diagnosed with CP.
Main Methods:
- A cohort of 120 unselected school children diagnosed with cerebral palsy were examined.
- Ocular status, including visual acuity, refractive errors, ocular motility, and visual fields, was assessed.
Main Results:
- Only 20% of children had normal ocular findings.
- High incidences were observed for squint (52.5%), significant refractive errors (50%), strabismic and anisometropic amblyopia (15%), and visual field defects (11%).
- Many identified ocular abnormalities were untreatable.
Conclusions:
- Children with cerebral palsy exhibit a high burden of ocular defects, necessitating routine ophthalmological evaluations.
- Early detection and management of treatable visual impairments are vital for optimizing educational outcomes and overall well-being.
- Identifying untreatable conditions is also important for educational planning and support.
Abstract:
School children severely afflicted with cerebral palsy, but unselected in regard to their visual status. have been studied. Of 120 children examined only 24 (20%) had normal eyes or ocular adnexae. Squint was found in 52.5% of the children and significant refractive errors in 50%. There was also a high incidence of strabismic and anisometropic amblyopia (15%) and visual field defects (11%). A number of other ocular abnormalities were found, the majority of which were not amenable to any form of treatment. Early identification of treatable ocular defects and their treatment along conventional lines is emphasised. It is also important to identify untreatable defects that may have a bearing on the child's education. These children need all the help available, and visual function should be at its best. A diagnosis of cerebral palsy has usually been made by the time such a child reaches 18 months of age. In view of the high incidence of ocular defects a full ophthalmological assessment should be part of the routine assessment of the child.
