OBJECTIVE: To evaluate the results of Ahmed Glaucoma Valve implantation in African American and white patients. METHODS: In this retrospective, comparative case-control study, we reviewed 86 eyes of 86 patients, comparing the surgical outcomes in white patients (n = 43) with matched African American patients (n = 43). Success was defined as an intraocular pressure (IOP) between 6 mmHg and 21 mmHg with or without glaucoma medicines, without further glaucoma surgery, and without loss of light perception (definition 1) and an IOP between 6 mmHg and 21 mmHg and achievement of a 20% reduction in IOP from the preoperative level (definition 2). RESULTS: The mean follow-up was 2.3 years for white patients and 2.5 years for African American patients (P = .50). At the last follow-up, the mean ± SD IOP was 15.3 ± 3.3 mmHg and 15.3 ± 3.5 mmHg (P = .77) in white and African American patients, respectively. Life table analysis showed a significantly lower success rate for African American patients compared with white patients by both definition 1 (P = .03) and definition 2 (P = .006). Cox proportional hazards regression analysis detected African American race as a risk factor for surgical failure by both definitions. Visual outcomes and complications were comparable between the 2 groups. CONCLUSION: African American patients have a greater risk of surgical failure after Ahmed Glaucoma Valve implantation compared with white patients.
