PURPOSE: To highlight the efficacy of primary Ahmed glaucoma valve implantation in angle recession glaucoma following blunt ocular trauma in Indian eyes. DESIGN: A retrospective analytical study. MATERIALS AND METHODS: This study included 52 patients of angle recession glaucoma, who presented between Mar 2006 to Feb 2016, out of which 38 patients had undergone primary AGV implantation, while the rest were managed with topical anti-glaucoma medications. Preoperative data included age, sex, type and mode of injury, duration of injury, assessment of best-corrected visual acuity (BCVA) and intraocular pressure (IOP). The extent of angle recession was observed by gonioscopy. The intraocular pressure, visual acuity, and the number of anti-glaucoma medications were measured postoperatively. The success of this technique was analyzed by using a Kaplan-Meier cumulative survival curve. RESULTS: Following AGV implantation, the mean IOP was significantly reduced to 8.7 ± 2.2 at 1st day, 10.1 ± 2.2 at 7th day, 14.2 ± 3.4 at 3rd month, 15.6 ± 3.7 at 1 year, and 15.6 ± 3.6 at 3rd-year follow-up showing statistically significant values (p < 0.001) at each visit. The IOP was successfully controlled at the last follow-up without topical treatment. Mean BCVA at 3 years -post-AGV was 0.144 (0.151) (LogMAR) which was statistically significant (p < 0.001) as compared to the mean BCVA of 0.898 (± 0.205) LogMAR units at presentation. The success rate by Kaplan-Meier survival curve analysis was 90% at the mean follow-up duration of 29.47 ± 3.39 months. Overall surgical complications were noted in the form of prolonged hypotony, hyphema in 7 patients (13.5%). CONCLUSIONS: In medically uncontrolled post-traumatic angle recession glaucoma, primary AGV Implantation is a safe and effective surgical procedure with lesser complication rates providing long-term IOP control in a younger population.
