方法：曲水县≥40岁1 115位藏族人群分为≥40～<50、 ≥50～<60、≥60～<70、≥70岁四个年龄段。所有受检人群进行眼科检查， 包括视力检查、非接触眼压测定， 前房深度测定， 采用SPSS 19.0统计软件进行数据分析及处理。

结果：藏族人群1 115位(2 145眼)平均眼压12.9±2.7mmHg， 男性眼压平均13.2±2.8mmHg， 女性眼压平均12.7±2.5mmHg。藏族人群1 115位(2 128眼)中周边前房1/2CT者占68.8%， 周边前房深度与年龄之间存在线性趋势， 年龄越大， 周边浅前房者越多(P<0.01)， 随着年龄的增长， 周边前房深度1/3CT者从≥40～<50岁人群占19.3%， 增加至39.2%(≥70岁人群)， 并且女性周边浅前房多于男性(P<0.01)。

结论：高原地区≥40岁藏族人群平均眼压低于平原约3mmHg， 鉴于眼压偏低、前房深度等因素高原青光眼更易漏诊， 建议重视高原青光眼的普查。

METHODS: A total of 1115 Tibetan permanent residents aged 40 years or older from the towns and villages of Qushui County were divided into four age groups: ≥40～<50 years, ≥50～<60 years, ≥60～<70 years, and≥70 years. All participants were carried out clinical ocular examinations including visual acuity, IOP, anterior chamber depth, ocular anterior segment and posterior segment examination. The relativity was analyzed during IOP, ages, gender and anterior chamber depth by SPSS 19.0.

RESULTS: The mean IOP of 1115(2145 eyes)Tibetan permanent residents aged 40 years or older was 12.9±2.7mmHg, 13.2±2.8mmHg in men and 12.7±2.5mmHg in women. The results showed that the participants with anterior chamber depth of 1/2 corneal thickness had 68.8% in 1115(2128 eyes)Tibetan permanent residents and anterior chamber depth decreases significantly with age(P<0.01), which anterior chamber depth(of 1/3 corneal thickness)was 19.3% aged ≥40～<50 subjects to 39.2% aged ≥70 subjects. Anterior chamber depth(1/3 corneal thickness)in women was significantly shallow than that in men(P<0.01).

CONCLUSION: The mean IOP of plateau subjects was significantly lower from that of plain subjects by approximately 3 mmHg. There are lower pressure, deeper anterior chamber depth in this population of 1115 Tibetan permanent residents. The more attention should be paid to screening for glaucoma in high plateau.
