KEY HIGHLIGHTS:

  • The prevalence of adolescent eye disease in remote areas of the Qinghai-Tibet Plateau has rarely been reported.

  • To understand the prevalence of common eye diseases in Tibet, ocular-disease screening on students from primary and secondary schools in Tibet were performed and compared to the prevalence in the Central China Plain.

  • The refractive status of students was evaluated with a Spot™ vision screener. The test was conducted three or fewer times for both eyes of each student and results with best correction were recorded.

  • A total of 3246 students from primary and secondary schools in the Tibet Naidong district were screened, yielding a refractive error rate of 28.51%, which was significantly lower than that of the plains group (56.92%).

  • In both groups, the prevalence of refractive errors among females was higher than that among males.

  • The study that Tibetan adolescents had a lower prevalence of refractive errors than did adolescents in the plains area, which may be related to less intensive schooling and greater exposure to sunlight.
