摘要

對周邊虹彩切除術後6個月到9年平均4年2個月的青光眼病人，一共31名44眼，做了眼壓、視神經乳頭、隅角等種種檢查，並分別進行3項激發試驗，包括暗房試驗（39眼27名），俯臥試驗（23眼16名），及暗房俯臥合併試驗（44眼31名）。實驗結果顯示：視神經乳頭發生青光眼變化的占15%，隅角仍舊閉鎖的占30%，而需要繼續藥物治療以控制眼壓的占57%。三項激發試驗中，暗房試驗、俯臥試驗之陽性率均為13%，而暗房俯臥合併試驗之陽性率則高達54%。因此我們推想對於閉鎖性青光眼，除了瞳孔閉鎖之外，類似水晶體閉鎖、虹彩根閉鎖的機轉也占有極重要的地位。

Thirty-one patients who had received peripheral iridectomy because of primary angle-closure glaucoma during the past 9 years, with the average of 4 years and 2 months postoperative follow-up, were proceeded for the present study. Of the 44 eyes of these 31 patients, 15% developed progressive glaucomatous cupping, 30% showed persistent angle closure, and 57% still required medical treatment with pilocarpine. Three provocative tests were also undertaken in these patients. The dark room test was performed in 39 eyes (27 patients), the prone test in 23 eyes (16 patients), and the prone-dark combined test in all 44 eyes (31 patients). The incidence of positive provocative tests was 13% for both dark room and prone tests. However, the prone-dark combined test revealed an as high as 50% incidence of positives. It is conceivable that the lens and iris root block may play just as an important role as pupillary block in the angle-closure glaucoma.
