Abstract Objective: For the first time to accurately and comprehensively analyze the characteristics and treatment of visual impairment children and adolescents with cerebral palsy in Kashgar, Xinjiang, to promote their early development of visual and general rehabilitation. Methods: This cross-sectional study selected children and adolescents with cerebral palsy who underwent eye screening in a general hospital in Kashgar, Xinjiang, Uygur Autonomous Region, in October 2018. Ophthalmic examinations were conducted, including refractive error, eye position, anterior segment and fundus examination. Their ophthalmic treatment history was also investigated. The data were analyzed by chi square tests. Results: One hundred seventysix children and adolescents with cerebral palsy were enrolled. The average age was 6.4 ± 2.7 years (0.8- 12 years), of which 97 cases (55.1%) were between 0.8 to 6 years old, 169 were Uighurs (96.0%) and 104 were males (59.1%). There were 105 cases(59.7%) with visual impairment, of which 3 cases (1.7%) were accompanied by two simultaneous visual disorders. The incidence of visual impairment was 61.7% (108 cases) that manifested as ametropia (48 cases, 27.3%), strabismus (43 cases, 24.4%) and other eye diseases (17 cases, 9.7%). Hyperopia (20 cases, 11.4%) was most common in ametropia, exotropia (25 cases, 14.2%) was most common in strabismus, and optic nerve atrophy, congenital glaucoma and congenital cataract (4 cases each, 2.3%) were the most common among other eye diseases. Only 27 cases (15.3%) received previous ophthalmic examinations, the remaining 149 cases (84.7%) were undergoing ophthalmic examinations for the first time, and only 6 of 105 cases (5.7%) with visual impairment had received ophthalmic examinations before. The incidence of myopia in all children and adolescents with cerebral palsy was 9.7% (17 cases). There was no significant difference in the incidence of myopia between children and adolescents with cerebral palsy when gender, age group, nationality and strabismus were taken into account. Conclusion: The incidence of visual impairment in children and adolescents with cerebral palsy is higher than that in normal children of the same age, and the incidence of strabismus is very high. However, the rate of children receiving ophthalmic examinations was low, it may due to their parents are not well aware of accompanying ophthalmic diseases. It suggests the urgency and importantance to popularize eye health screening in cerebral palsy children and adolescents.
