Abstract
Purpose::
Cerebral palsy is a non progressive brain lesion. Various brain functions are affected including vision, motility, etc. This study was planned to investigate if reduced visual resolution and strabismus in cerebral palsied (CP) children are related to the kinetic severity and certain brain magnetic resonance imaging (MRI) findings.
Methods::
80 children participated in this study. Gross motor functional classification system (GMFCS), brain MRI and eye testing with visual resolution and strabismus assessment by visual functional assessment - K test (VFA - K test) were performed. Children with epilepsy or severe eye operations were excluded.
Results::
MRI showed that 91.2% of the children appeared with mild to severe periventricular leucomalacia (PVL) or PVL with cortical atrophy; GMFCS showed that 77.5% of the children appeared with moderate to very severe kinetic disability. Normal visual resolution appeared in 50% of children, 50.1% children with orthophoria and the rest with strabismus.
Conclusions::
Children with mild to moderate disability appeared with better visual level and reduced incidence of strabismus. In contrast children with moderate to severe PVL, or PVL and cortical atrophy, appeared with the highest incidence of visual dysfunction.
