Secondary stenting of glaucoma drainage implant: a novel technique for treatment of late hypotony

Glaucoma drainage devices have become increasingly popular as a surgical option for the treatment of uncontrolled glaucoma.1 A number of surgical techniques have been described to prevent immediate postoperative hypotony while using non‐valved implants,2-4 including ligation of the drainage tube with a self‐absorbing suture.5 However, there is a chance of sudden hypotony when the suture dissolves. Eyes with uveitis have impaired aqueous production6 and thus may be at increased risk of this complication.7 We describe a simple surgical technique of secondary internal stenting of the glaucoma drainage device used to effectively manage this clinical scenario in two of our patients.
