Visual impairment due to a dyskinetic eye movement disorder in children with dyskinetic cerebral palsy

Abstract: Neurological lesions that cause dyskinetic cerebral palsy (CP) commonly involve ocular movements. This report describes a group of 14 children (nine males, five females) whose CP is associated with severe dyskinetic eye movements. Ages ranged from 4 months to 13 years (mean 6.9 years). Clinical features of this eye movement disorder are discussed and defined. The visual function of these children is slow, variable, and highly inefficient. They are often misdiagnosed as blind, due to cortical visual impairment.… Show more

“…The differing prevalence of visual impairment conditions is associated with variations in the time and severity of brain damage, involvement location, and thus the occurrence of different visual problems according to CP type. The literature contains studies to define visual findings in a CP type14, 15 ) . However, the important thing is that children with CP commonly experience visual problems; therefore, eye examination should certainly be made, even if there is no visible finding.…”

“…Also, information obtained from the innovative neurological tests may improve the quality of intervention services secondary to an im proved understanding of the nature of the neurological structures involved. In chil dren who were initially assumed to have significant visual impairments, EEG, CT, and MRI technologies were able to identify the cause of their severe visual inattentive ness as being due to dyskinetic eye move ments, rather than the loss of visual acuity (Jan, Lyons, Heaven, & Matsuba, 2001). Diagnostic information yielded by these tests resulted in more appropriate interven tion strategies.…”

“…Ocular abnormalities were found in 60 (98%) of 61 participants. Refractive errors were found in 48 (78.7%) participants: hypermetropia (16), astigmatism (six), myopia (six), and associated refractive errors (20: hypermetropia and astigmatism in 14, myopia and astigmatism in six).…”
