Pupillary block glaucoma developed in 3 children treated with irrigation and aspiration using the Cavitron phacoemulsification system. One had a congenital cataract, 1 had blunt trauma, and 1 had a penetrating injury. The factors contributing to pupillary block included excessive retained lens material, severe post-traumatic inflammation with synechia formation in 2 cases, and the lack of iridectomy in a case requiring a membrane discission. The pupillary block was successfully treated by pars plana vitrectomy in all cases; however, vision in 1 eye was lost owing to secondary glaucoma resulting from delay in treatment and the development of 360 degrees peripheral anterior synechiae.
3名使用Cavitron超声乳化系统进行冲洗和抽吸治疗的儿童发生了瞳孔阻滞性青光眼。其中1名患有先天性白内障，1名遭受钝挫伤，1名有穿透伤。导致瞳孔阻滞的因素包括残留过多晶状体物质、2例因严重创伤后炎症形成了虹膜粘连，以及1例在需要进行膜切开时未行虹膜切除术。所有病例均通过玻璃体切除术成功治疗了瞳孔阻滞；然而，1只眼因治疗延误继发青光眼并出现360度周边前粘连而丧失视力。
