Purpose

To investigate the Risk factors for AGV ( Ahmed glaucoma valve) failure.

Setting

Imam Hossein nMedical Center, Tehran, Iran.

Methods

A retrospective analysis of patients' medical records with varying glaucoma causes who underwent AGV implantation. The primary measure of success was the cumulative achievement of an intraocular pressure (IOP) between 5 and 21 mmHg, with a 20 % reduction from baseline, with or without medication to lower IOP. The secondary measures of success were IOP levels and the number of glaucoma medications used.

Results

The study enrolled 120 participants, with an average age of 48.9 ± 19.6 years of age. The average follow-up period was 4.5 ± 1.4 years. The mean survival duration was 5.3 ± 0.5 years in patients with hypertensive phase (HP), which was significantly shorter than the 6.4 ± 0.2 years in those without HP. The likelihood of surgical failure was also correlated with higher baseline IOP, with an odds ratio of 1.07 (95 % confidence interval: 1.02-1.12). In a logistic regression model, the presence of neovascular glaucoma was the only factor significantly associated with AGV failure, with an odds ratio of 3.14 (95 % confidence interval: 1.2-8.1).

Conclusion

Based on our findings neovascular glaucoma, a higher baseline IOP and the presence of hypertensive phase are risk factors for AGV failure.
