During the course of negative provocative test for closed-angle glaucoma using pilocarpine and phenylephrine 60% of eyes develop significant reductions in outflow facility at some stage during the test. It is shown that these reductions can be explained by postulating the presence of partial-angle closure since: (1) A random sample (6) of 53 eyes showing an abnormal response subsequently had a peripheral iridectomy. On reprovoking they then behaved as normal eyes with a uniform increase in outflow. (2) Fifty-eight eyes that had a peripheral iridectomy for closed-angle glaucoma (spontaneous or induced) responded to provocative testing as do normal eyes.
在使用毛果芸香碱和60%去氧肾上腺素进行闭角型青光眼阴性激发试验的过程中，60%的眼睛在试验的某个阶段房水流出易度出现显著降低。结果表明，这些降低可通过假定存在部分房角关闭来解释，因为：（1）随机抽取的53只显示异常反应的眼睛中有6只随后进行了周边虹膜切除术。再次激发时，它们的表现如同正常眼睛，房水流出均匀增加。（2）58只因闭角型青光眼（自发或诱发）接受周边虹膜切除术的眼睛对激发试验的反应与正常眼睛相同。
