Abstract： Objective: To investigate the prevalence of amblyopia and its influencing factors among primary and secondary school students in Metuo County, Nyingchi City, Tibet Autonomous Region. Methods: This was a cross-sectional survey. In May 2017, a total of 833 students from urban primary and middle schools in Metuo County were surveyed for visual acuity survey and basic eye examinations, including visual acuity, refractive, anterior segment, fundus and eye position examination, etc. A questionnaire was used to survey the students diagnosed with amblyopia and the causes were analyzed. Fisher's exact test, Chi-square test and logistic regression were used to analyze the data. Results: A total of 833 primary and secondary school students in Motuo county participated in the survey, among whom 22 had amblyopia. The prevalence of amblyopia was 2.6%. And the cause of amblyopia included anisometropia in 10 cases, accounting for 45%; 6 cases of refractive error, accounting for 27%; 3 cases of strabismus occurred in 3 patients, accounting for 14%. There were 2 patients with form deprivation, accounting for 9% and 1 other patient, accounting for 5%. Gender and age were not the influencing factors for the prevalence of amblyopia. Conclusions: The prevalence of amblyopia among primary and secondary school students in Motuocounty is higher than prevalence of whole China. Anisometropia and refractive error are the main causes of amblyopia.
