Although 25 eyes presented with acute angle closure glaucoma, 6 eyes were insidious onset and asymptomatic. While 27 eyes relieved pupillary block after laser iridotomy or surgical peripheral iridectomy, 4 eyes required vitrectomy or laser photomydriasis to relieve pupillary block. Five eyes (16%) developed chronic angle closure glaucoma due to peripheral anterior synechia. one could be controlled by chronic medical therapy, three required trabeculectomy, the another one even required cyclocryotherapy because poor IOP control after trabeculectomy.

虽然大多数的病例（25只眼）以急性发作为临床表徵，但有6只眼为隐袭性，无任何临床症状。27只眼经雷射虹彩瞳孔术或外科周边虹彩切除术后可以解除瞳孔阻塞，另4只眼无法解除而需作玻璃体切除术或雷射光瞳孔放大术。5只眼(16%)因周边前黏连发生慢性隅角闭锁性青光眼，其中1只眼可以药物控制，3只眼需做小梁切除术，另1只眼做小梁切除术后眼压仍无法控制而接受睫状体冷冻治疗。
