Comprehensive visual impairment evaluation for cerebral palsy children
摘要
Abstract
Abstract•AlM: To evaluate the visual impairment in cerebral palsy children with series objective indicators, and conclude their clinical features of visual function.• METHODS: Objective tests including following pursuing test, optokinetic nystagmus(OKN) drum test, refractive error examination, fundus examination, ocular deviation examination, pattern visual evoked potential ( P-VEP ) tests and brain magnetic resonance imaging ( MRl) were carried out in 43 cerebral palsy children ( 86 eyes ) with ocular visual dysfunction; The visual impairment data of the cerebral palsy children were collected, and the clinical features and possible mechanism were analyzed.•RESULTS: 1. Of the 43 cerebral palsy children ( 86 eyes) with the visual impairment presented diversified, 25 ( 50 eyes, 58. 1%) of refractive error, 24 ( 48 eyes, 55. 8%) of strabismus, 12 ( 24 eyes, 27. 9%) with nystagmus, 19 ( 38 eyes, 44. 2 %) of optical nerve atrophy or hyperplasia, 35 ( 70 eyes, 81. 4%) of VEP abnormality. Among children with spastic cerebral palsy, the incidence of visual impairment was statistically significant difference compared with other groups (P<0. 01). 2. There were 16 cases (32 eyes,37. 2%) with esotropia, 6 cases ( 12 eyes, 14. 0%) with exotropia and 2 cases ( 4 eyes, 4. 7%) with vertical deviation. Strabismus was most common in spastic cerebral palsy children, totally 13 (26 eyes, 30. 2%) with esotropia, and exotropia was common in hypotonia and other types cerebral palsy children; 3. 23 ( 46 eyes, 53. 5%) with hyperopia, 8 ( 16 eyes, 18. 6%) with myopia, 16 ( 32 eyes, 37. 2%) with astigmutism and 14 cases (28 eyes, 32. 6%) with anisometropia;4. Cerebral palsy children were usually with decreased VEP amplitude and prolong latency, and poor wave formation, mostly in spastic cerebral palsy children; 5. Visual abnormality was most common in occipital cortex damage and periventricular leukomalacia ( PVL ) . The incidence in PVL and occipital cortex had no statistically significant difference ( P > 0. 05 ), no nystagmus in patients with severe occipital cortex damage.•CONCLUSlON: Cerebral palsy children were usually with visual impairment, and presented with special clinical features; Comprehensive objective visual tests are accurate and reliable for evaluation of the visual function in cerebral palsy children.关键词
