Abstract
Laser iridotomies in dark coloured irides are associated with higher complication and failure rates. A prospective clinical study to evaluate the use of the argon and Nd:YAG laser in sequential combination for iridotomy was carried out on 20 eyes of 13 patients with dark irides. Patent iridotomies were achieved in single treatment sessions for all the eyes. Iridotomy closure was observed in one eye during a mean follow-up period of 14 months (range 6-20 months). Complications from the treatment occurred in five eyes and were minor. Total mean energy used for the argon and Nd:YAG stages respectively were a third of most studies on pure argon and Nd:YAG iridotomies. Sequential argon-YAG laser iridotomy combines most of the advantages of both laser types while avoiding some of their disadvantages. We find it a safe and effective tool for iridotomy in otherwise difficult dark irides.
摘要
深色虹膜行激光虹膜切开术的并发症和失败率较高。对13例深色虹膜患者的20只眼进行了一项前瞻性临床研究，以评估氩激光和Nd:YAG激光序贯联合用于虹膜切开术的效果。所有眼睛均在单次治疗中成功形成了通畅的虹膜切开。在平均14个月（范围6 - 20个月）的随访期内，有一只眼睛观察到虹膜切开闭合。治疗并发症发生在5只眼中，均较轻微。氩激光和Nd:YAG激光阶段分别使用的总平均能量仅为大多数单纯氩激光和Nd:YAG激光虹膜切开术研究的三分之一。氩 - YAG激光序贯虹膜切开术结合了两种激光类型的大部分优点，同时避免了一些缺点。我们发现它是一种用于原本困难的深色虹膜进行虹膜切开术的安全有效的工具。
