Posterior pupillary synechiae affect a proportion of eyes subjected to iridectomy with or without drainage operation because (1) aqueous humour bypasses the pupil; (2) traumatic iridocyclitis occurs; (3) there is immobility of the iris in the iridectomy sector; (4) in eyes with angle closure glaucoma closer apposition of the iris to the anterior lens capsule increases the tendency; (5) pilocarpine aggravates (4) both in angle closure glaucoma and open angle glaucoma and produces a small immobile pupil facilitating pupillary membrane formation (occlusio pupillae). Pilocarpine should be avoided if possible as medical treatment at any time after a drainage operation. A beta blocker is the drug of choice. To eliminate posterior synechiae over a fair number of degrees of pupil (say 30 degrees) sector iridectomy can be done.
瞳孔后粘连会影响一部分接受了虹膜切除术（无论是否进行引流手术）的眼睛，原因如下：（1）房水绕过瞳孔；（2）发生外伤性虹膜睫状体炎；（3）虹膜切除术区域的虹膜活动受限；（4）在闭角型青光眼患者中，虹膜与晶状体前囊更紧密的贴合增加了这种趋势；（5）毛果芸香碱在闭角型青光眼和开角型青光眼中都会加重（4）的情况，并产生一个小的固定瞳孔，促进瞳孔膜形成（瞳孔闭锁）。在引流手术后的任何时候，作为药物治疗，应尽可能避免使用毛果芸香碱。β受体阻滞剂是首选药物。为了消除相当程度（比如30度）的瞳孔后粘连，可以进行扇形虹膜切除术。
