眼前节分析系统房角检查

Chamber angle examination by anterior eye segment analysis system

目的 对眼前节分析系统和裂隙灯显微镜房角镜 2种眼前房角检查方法进行比较。方法 对 8例 16眼的眼前房角分别用眼前节分析系统和裂隙灯显微镜房角镜 2种方法进行检查 ,采用 Spaeth分级系统记录结果 ,采用线性相关和等级相关方法对 2种方法所得结果进行统计学分析。结果 2种检查方法在判断房角入口角度、虹膜根部附着点和周边虹膜形态 3个方面均有相关性 ,其中房角入口角度相关性最好 ;窄角状态时结果一致性较差。结论 眼前节分析系统房角检查基本不受照明光和机械作用干扰 ,能定量测量房角入口角度 ,对周边虹膜形态判断准确 ,信息保存方便 。

Objective To compare the consistency of the chamber angle examination by anterior eye segment analysis system and gonioscope.Methods Eight patients (16 eyes ) were selected for this research. These eyes were examined by anterior eye segment analysis system and gonioscope respectively and recorded using the Spaeth classification system. The results of the two methods of chamber angle examination were compared and the data were analyzed with linear correlation test and Spearman correlation test.Results The results of these two methods of chamber angle examination were consistent in judging the angle, the iris root insertion and the peripheral iris morphology. The consistency was best when the angle was evaluated. The consistency was relatively poor in a narrow angle. Conclusion Anterior eye segment analysis system can measure chamber angle quantitatively, evaluate the peripheral iris morphology reliably and preserve information conveniently, not interfered by illumination and mechanism. It is useful in diagnose and treatment of angle closure glaucoma.
