Ahmed glaucoma valve implant (AGV) is one of the more commonly used implants in difficult glaucomas. The histology of a functioning bleb following AGV implantation and its anatomic relationship to the optic nerve when placed in the superionasal quadrant has been described. We report the histology of a failed bleb and the anatomic relationship between the optic nerve and the AGV end-plate when placed 9 mm from the limbus in a patient with neovascular glaucoma.

Objective: To assess clinical outcomes and establish the incidence and management of a hypertensive phase (HP) (defined as intraocular pressure [IOP] > 21 mmHg in the first 6 postoperative months) in patients with Ahmed glaucoma valve implant.

Design: Retrospective noncomparative case series.

Participants: A total of 85 patients were included in the current study, including consecutive patients who had intractable glaucoma and underwent Ahmed valve implant insertion at the University Glaucoma Center, Tampa, Florida (DWR and WEL) and the Massachusetts Eye and Ear Infirmary (PAN) between January 1993 and June 1997.
