Argon laser peripheral iridoplasty is a useful procedure to eliminate appositional angle closure resulting from mechanisms other than pupillary block. For those eyes with angle closure originating at an anatomic level posterior to the iris, such as plateau iris, lens-induced angle closure, or posterior segment processes (malignant glaucoma, central retinal vein occlusion, etc.), laser iridotomy by itself may be insufficient to treat the underlying disease mechanism. Argon laser peripheral iridoplasty is often useful in these cases to further open the angle. It can be used to break an acute attack of angle-closure glaucoma and relieve appositional angle closure secondary to plateau iris syndrome, or lens-related angle closure, and to widen the angle prior to argon laser trabeculoplasty. Peripheral location of long-duration, low-power, large spot size laser burns is essential for optimal success.
氩激光周边虹膜成形术是一种有效的手术方法，可消除瞳孔阻滞以外的机制导致的贴附性房角关闭。对于那些房角关闭起源于虹膜后方解剖层面的眼睛，如高原虹膜、晶状体诱导的房角关闭或后段病变（恶性青光眼、视网膜中央静脉阻塞等），单纯激光虹膜切开术可能不足以治疗潜在的疾病机制。在这些情况下，氩激光周边虹膜成形术通常有助于进一步开放房角。它可用于打破急性闭角型青光眼发作，缓解高原虹膜综合征或晶状体相关房角关闭继发的贴附性房角关闭，并在氩激光小梁成形术前扩大房角。长时间、低功率、大光斑尺寸的激光烧灼位于周边对于取得最佳效果至关重要。
