评价闭角性青光眼有二个主要问题:(1)房角是开放的还是闭合的,(2)若房角是闭合的,则是接触性闭合还是粘连性闭合。作者通过对5例(10眼)闭角性青光眼的检查,比较了各型房角镜以及手术加深前房法(surgical chamber deepening procedure)在弄清以上二个问题中的有效性。结果如下: 决定房角的开放或闭合以Koeppe型房角镜最为准确。由于其宽基底(12mm)、高圆顶以及检查过程中不必手持加压以固定其位置,所以不会因角膜加压而引起周边房角变形或人为的开放。
Evaluation of closed-angle glaucoma has two main problems: (1) the angle is open or closed, (2) if the angle is closed, is the contact closure or adhesive closure. By examining five cases (10 eyes) of closed-angle glaucoma, the authors compared the effectiveness of various types of gonioscopy and surgical chamber deepening procedure in clarifying the above two issues. The results are as follows: The decision to open or close the corner is the most accurate with a Koeppe goniometer. Due to its wide base (12mm), high domes and the absence of hand-held pressure during inspection to fix its position, there is no angular deformation or artificially opening around the cornea due to compression.
