Indications for glaucoma drainage implants devices

Glaucoma drainage devices (GDDs) have become an essential surgical option for managing glaucoma, particularly in cases where conventional treatments are ineffective or high risk. Initially reserved for refractory glaucoma, their indications have expanded due to advancements in design and improved surgical outcomes. This chapter explores the key indications for GDDs, including refractory glaucoma, failed filtration surgeries, and patients at high risk of trabeculectomy failure. Understanding these indications is crucial for selecting appropriate candidates and optimizing long-term intraocular pressure (IOP) control, thereby preserving vision and improving patient outcomes.
