Pak J Ophthalmol Jan ;40(1):72-6.

Purpose: To determine the early and late complications of Ahmed Glaucoma Valve (AGV) implant surgery. Study Design: Interventional case series. Place and Duration of Study: Ophthalmology department of MTI-Hayatabad Medical Complex Peshawar, from May 2018 to February 2023. Methods: All the patients between May 2018 and February 2023 who underwent AGV implant were included in the study. Data included patient`s age, gender, indications for surgery, type of AGV implant used, length of follow-up period, intraocular pressure (IOP), number of topical glaucoma medications used, early and late complications, and the final outcome. Continuous variables (duration of follow-up, best corrected visual acuity, IOP, and number of topical anti-glaucoma medications) were represented in means and standard deviations. Paired t-test was applied for comparison of means between baseline and last follow-up data. A p-value of < 0.05 was considered statistically significant. Results: A total of 28 eyes were included. Mean age of the patients were 28.75 +- 20.5 years. Duration of follow-up was 213.96 +- 169.33 days. There were 53.85% females. Commonest indication was congenital glaucoma 7 (25%). Majority, (n = 18, 64.3%) of the eyes had previous cataract surgeries followed by glaucoma, 13 (46.4%). The commonest early post-operative complication was hyphema (25%) and commonest late complication was hypertensive episode 32.1%. Majority of the eyes 23 (82.1%) did not require any further intervention for these complications. Conclusion: Majority of AGV complications are self-limiting, necessitating just conservative therapy. However, serious complications might happen that could lead to blindness, therefore the surgeons should have strategies for treating or preventing them.
