BACKGROUND
Children with cerebral palsy are known to be at increased risk for visual impairment.
METHODS
In a population-based sample drawn from a geographically defined registry, the profile of visual impairment in children with cerebral palsy was investigated.
RESULTS
Close to half (49.8%; 106/213) had a visual impairment. The majority of these individuals had strabismus (55.7%; 59/106) and a slightly lesser fraction had refractive errors (20.7%; 22/106) or severe visual loss (18.9%; 20/106). The vast majority of children with severe visual loss had spastic quadriplegia (83%; 17/20) or were nonambulatory (i.e., Gross Motor Function Classification Scale IV/V, 80%; 16/20).
CONCLUSIONS
Knowledge of this profile will assist practitioners to heighten their appreciation of potential visual disturbances in certain subsets of children with cerebral palsy.
背景
已知脑瘫患儿视力受损风险增加。
方法
在从地理界定登记处抽取的基于人群的样本中，对脑瘫患儿的视力受损情况进行了调查。
结果
近半数（49.8%；106/213）患儿存在视力受损。其中大多数人患有斜视（55.7%；59/106），屈光不正的比例略低（20.7%；22/106）或严重视力丧失（18.9%；20/106）。绝大多数严重视力丧失的儿童患有痉挛性四肢瘫痪（83%；17/20）或无法行走（即粗大运动功能分类量表IV/V级，80%；16/20）。
结论
了解这一情况将有助于从业者提高对某些脑瘫患儿潜在视力障碍的认识。
