There is very little information on the prevalence of ocular diseases in Tibetan children who live in the remote areas of the Qinghai-Tibetan Plateau. The purpose of this study was to investigate the prevalence of ocular diseases in primary school children between 6 and 14 years of age in the rural Tibetan area of Maqin County, China.
All the children from 8 Tibetan township primary schools in Maqin County underwent a full eye examination by a team of 6 senior ophthalmologists.
A total of 1084 children were included in this investigation, of which 199 (18.36%, 95% confidence interval [CI] 16.05-20.66) had ocular morbidity. Of these, 98 were male and 101 were female. Refractive errors were found in 11.07% (95% CI 9.20-12.94), strabismus in 2.49% (95% CI 1.56-3.42), corneal leukoma in 1.20% (95% CI 0.55-1.85), amblyopia in 1.02% (95% CI 0.42-1.61), and vernal conjunctivitis in 0.65% (95% CI 0.17-1.12). Monocular blindness was seen in 16 cases (1.48%, 95% CI 0.76-2.19). Trauma was the most common cause of blindness.
The prevalence of eye disorder is high among school-aged Tibetan children in Maqin County, representing an important health problem. More effort should be devoted to the study, prevention, and treatment of these diseases. Effective strategies are needed to reduce the incidence of visual impairment in this population of children.
关于生活在青藏高原偏远地区的藏族儿童眼部疾病患病率的信息非常少。本研究的目的是调查中国玛沁县农村藏族地区6至14岁小学生眼部疾病的患病率。
玛沁县8所藏族乡镇小学的所有儿童均由6名资深眼科医生组成的团队进行了全面的眼部检查。
本调查共纳入1084名儿童，其中199名（18.36%，95%置信区间[CI]16.05 - 20.66）患有眼部疾病。其中，男性98名，女性101名。屈光不正的患病率为11.07%（95%CI 9.20 - 12.94），斜视患病率为2.49%（95%CI 1.56 - 3.42），角膜白斑患病率为1.20%（95%CI 0.55 - 1.85），弱视患病率为1.02%（95%CI 0.42 - 1.61），春季结膜炎患病率为0.65%（95%CI 0.17 - 1.12）。单眼盲16例（1.48%，95%CI 0.76 - 2.19）。外伤是失明的最常见原因。
玛沁县学龄藏族儿童眼部疾病患病率较高，这是一个重要的健康问题。应更加努力地对这些疾病进行研究、预防和治疗。需要有效的策略来降低该儿童群体中视力损害的发生率。
