Glaucoma drainage implants have been used with increasing frequency for the management of glaucoma. Patients who are candidates for glaucoma drainage devices often have more severe disease and are at risk of vision loss with post-operative elevations in intraocular pressure (IOP). One post-operative complication that can result in IOP elevation after glaucoma drainage device implantation is occlusion of the tube lumen.
Here, we present a novel case of tube occlusion by the anterior capsule in a patient who underwent combined phacoemulsification and Ahmed glaucoma valve implantation. The tube occlusion was successfully managed with Nd:YAG capsulotomy with immediate IOP lowering.
While there have been previous reports of occlusion of the tube lumen by vitreous, iris, blood and fibrin, to our knowledge this is the first report of tube occlusion by the anterior lens capsule and the first report to describe its successful management.
青光眼引流植入物在青光眼治疗中的应用频率日益增加。青光眼引流装置的适用患者往往病情更为严重，存在术后眼压升高导致视力丧失的风险。青光眼引流装置植入术后可导致眼压升高的一种术后并发症是管腔阻塞。
在此，我们报告一例在接受白内障超声乳化吸除术联合艾哈迈德青光眼引流阀植入术的患者中，前囊膜导致引流管阻塞的罕见病例。通过钕钇铝石榴石激光晶状体前囊切开术成功处理了引流管阻塞，眼压随即降低。
虽然此前已有玻璃体、虹膜、血液和纤维蛋白导致管腔阻塞的报道，但据我们所知，这是首例前晶状体囊膜导致引流管阻塞的报道，也是首例描述其成功处理方法的报道。
