Comparison between primary Ahmed valve implantation and primary trabeculectomy with mitomycin C in pseudophakic patients with exfoliative glaucoma.

Purpose: To compare the efficacy and safety of primary Ahmed valve implantation (AVI) and primary trabeculectomy with mitomycin C (MMC) in patients with pseudophakic exfoliative glaucoma (XFG).

Methods: All enrolled patients were divided into two groups: the TRAB group, comprising patients who underwent trabeculectomy with MMC, and the AVI group, comprising patients who underwent AVI. Intraocular pressure (IOP), mean deviation (MD), endothelial cell density of cornea (ECD), and the number of topical anti-glaucoma agents used during study period were retrospectively analyzed.
