The EX-PRESS Glaucoma Filtration Device is a stainless steel, nonvalved filtration device that channels aqueous humor through a secure lumen to a half-thickness scleral flap, creating a subconjunctival filtration bleb. Elevated postoperative intraocular pressure may indicate occlusion of the device lumen or episcleral fibrosis, and it is essential to reestablish the flow in a timely manner to prevent bleb formation failure. We report the successful use of an extendible 41-G subretinal injection needle to rapidly restore device patency when the conventional bleb revision was not effective.
