Purpose: To compare Baerveldt 350 and Ahmed S-2 implants in the treatment of glaucoma refractory to medical therapy. Methods: A retrospective review of 45 patients who underwent glaucoma shunt implantation by two surgeons (APC, ADB) from 1997-2001. Clnical data was tabulated pre and post operatively at day 1, 1 month, 6 months, and 1 year. Failure was defined as IOP ≷21 or <6 mm Hg at the most recent visit, progression to NLP, additional glaucoma surgery, or sight threatening complications. Results: Average IOPs (mmHg) for each shunt are shown below. Overall success rates were 76.2% for Ahmed implants and 87.5% for Baerveldt implants. Causes of failure for Ahmed patients were uncontrolled IOP (19%) and corneal decompensation (4.7%). For the Baerveldt implant the causes of failure were corneal decompensation (8.3%) and surgical intervention (4.2%). In addition 14.2% of Ahmed patients and 16.6% of Baerveldt patients had choroidal detachments. Conclusion: The Baerveldt implant had a higher success rate then the Ahmed implant at one year.
