中老年人群前房角状态的调查

The survey of anterior chamber angle in a population of middle and old age

目的了解我国中老年人群前房角的情况，为闭角型青光眼的筛检提供依据。方法在广东省斗门县四个镇随机抽取５０岁以上２００人作为样本，应用Ｇｏｌｄｍａｎｎ房角镜检查样本人群的前房角，并行Ｓｐｅａｔｈ房角分级。结果２００人（３９０只眼）中，１２０％（下象限）～３００％（上象限）的前房角为Ｓｈａｆｅｒ分级≤２；周边虹膜高度膨隆者占１１３％（下象限）～２６４％（上象限）；虹膜根部附着点在巩膜突者占２７７％（下象限）～４２６％（上象限）；房角三种形态男、女间与年龄组间的差异均有显著性。结论老年人窄房角率较高，女性较男性高，并有随年龄增长而增高的趋势。

Objective To determine the condition of anterior chamber angle in a population of middle and old age, and afford data for screening of angle closure glaucoma.Methods Two hundred people aged 50 years or older were selected by random sampling in four districts of Doumen county. The anterior chamber angle of all people was evaluated by Goldmann one mirror gonioscope, and the angle was graded according to the Spaeth and Shaffer′s grading system.Results Three hundred ninety eyes were examined, 12% (inferior angle) to 30% (superior angle) were Shaffer′s grade ≤2. 11 3% (inferior) to 26.4% (superior) were anterior bowing of the peripheral portion of the iris, 27.7% (inferior) to 42.6% (superior) were iris insertion into seleral spur. The three aspects of the angle had significant differences in sex and age.Conclusion The survey shows that the percentage of people with occludable angles increases significantly with age, and women with occludable angles are more than men. This result is important for us to make screening strategy of primary angle closure glaucoma.
