AIM To identify and evaluate measures of visual ability utilised with children with cerebral palsy (CP).
METHOD Eight databases were searched for measures of visual ability. Key selection criteria for measures were: (1) use with children with CP, and (2) focus of visual ability measurement at Activities and Participation domain of the International Classification of Functioning, Disability and Health (ICF). The Consensus-based Standards for the Selection of Measurement Instruments (COSMIN) Checklist was used to assess psychometric properties.
RESULTS From 6763 papers retrieved, 25 were relevant and 19 measures of visual ability were identified. Only ten measures were supported with evidence of validity or reliability. No discriminative measure analogous to existing CP functional classification systems was found. No outcome measure valid for evaluation of visual abilities of children with CP was found.
INTERPRETATION Vision impairment is recognised as relevant to the functioning of children with CP, however measurement of vision is most often focused at Body Function levels, e.g. visual acuity. Measuring visual abilities in the Activities and Participation domain is important in considering how a child with CP functions in vision-related activities. The lack of psychometrically strong measures for visual ability is a gap in current clinical practices and research.
