The Ahmed Baerveldt Comparison Study methodology, baseline patient characteristics, and intraoperative complications.

ABSTRACT:

Purpose

The Ahmed Baerveldt Comparison (ABC) Study compares the long-term outcomes and complications of the Ahmed glaucoma valve (AGV; model FP7; New World Medical, Los Ranchos, CA) and the Baerveldt glaucoma implant (BGI; model 101-350; Abbott Medical Optics, Abbott Park, IL).

Design

Multicenter, randomized, controlled clinical trial.

Participants

Two hundred seventy-six glaucoma patients at 16 clinical centers worldwide who were 18 to 85 years of age with inadequately controlled intraocular pressure (IOP; ≥18 mmHg) in whom placement of an aqueous shunt was planned.

Methods

Study patients were randomized to undergo implantation of an AGV or a BGI.

Main outcome measures

Failure, defined as IOP >21 mmHg or not reduced by 20% less than baseline or IOP ≤5 m
