目的：为确定闪光试验和货车Herick试验在检测可闭合前房角中的可靠性和有效性，由两名观察者对我们门诊连续96例新患者独立进行闪光试验、货车Herick试验和前房角镜检查。使用加权Kappa统计确定观察者间一致性。使用青光眼专家的评估闭塞的角度（评估前房角镜检查）作为金标准，两个测试的敏感性和特异性进行了calculated.Results：所有三个测试显示出良好的协议（Kappa超过0.75）。闪光灯试验的敏感性和特异性分别为45.5%和82.7%。货车Herick试验阳性率为61.9%，阴性率为89.3%。结论：手电筒试验和货车Herick试验作为可闭角的筛选试验，其应用价值有限。
Objective: To determine the reliability and validity of the flashlight test and van Herick's test in detecting occludable anterior chamber angles.Methods: The flashlight test, van Herick's test and gonioscopy were performed independently by two observers on 96 consecutive new patients in our outpatient clinic. Interobserver agreement was determined using the weighted Kappa statistic. Using the glaucoma specialist's assessment of occludability of the angle (assessed by gonioscopy) as a gold standard, the sensitivities and specificities of the two tests were calculated.Results: All three tests showed good agreement (Kappa more than 0.75). The sensitivity and specificity of the flashlight test were 45.5% and 82.7% respectively. For the van Herick's test they were 61.9% and 89.3%.Conclusion: The flashlight test and van Herick's test are of limited use as screening tests for occludable angles.
