EX-PRESS ab-externo Revision With a 41-gauge Needle

Description

The EX-PRESS Glaucoma Filtration Device is a stainless steel, non-valved 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 fashion to prevent bleb formation failure. We report the successful use of an extendible 41G subretinal injection needle to rapidly restore device patency when the conventional bleb revision was not effective.
