摘要

本文在青光眼門診病人計43人60眼施以氪氣與氬氣雷射穿扎術，于以3年以上之追踪觀察，發現(1)三期次以內的燒灼均可成功的保持暢通，(2)孔洞邊緣的色素增生可阻塞孔洞，亦可促進虹膜的吸收，故在第二星期做第二期較在一星期內效果較佳，(3)安全孔洞最少在l.6mm直徑以上，(4)併發症除晶體混濁不變片，瞳孔變形及角膜局部混濁均可緩解，(5)孔洞長期追踪後，有增大的現象，(6)隅角呈有意義的增寬干均增加0.40 Shaffer's grading，(7)房水流出率雖平均增加0.022但無統計上之意義，(8)可證明其為一安全有效的方法，除可代替手術外，並可用以評估眼壓升高的機轉。

We selected 43 patients (60 eyes) from our glaucoma clinic for Argon or Krypton laser iridotomies and were followed for more than 3 years.
We found that (1) Within 3 sessions the laser iridotomy site can successfully remains patent. (2) Pigment proliferation at the crater can not only obstruct the opening but also increase the absorption rate of the edge. Therefore it is better to operate the second session of laser iridotomy at the second week rather than the first week. (3) If the diameter of the hole is greater than 1.6 mm there will not be any closure of the hole. (4) Among the complications only the local lens opacity remains static, the pupil distortion can improve and the local corneal opacity can resolve. (5) The iridotomy crater size increases as time passes on, especially during the first year. (6) The pressure gonioscopy for following up shows the angle is widened with an average of 0.40 on Shaffer's grading. (7) The outflow facility showed no statistically significant improvement although there was a 0.022 Cumm/Min/mmHg average increase. (8) It is proven that laser iridotomy is a safe and effective method, not only can replace surgical iridectomy, but also serves for the differentiation of glaucoma mechanism.
