Evaluation of the hypertenive phae after inertion of the Ahmed Glaucoma Valve

Purpoe To invetigate the potoperative hypertenive phae (HP) in patient undergoing glaucoma drainage implant urgery. Deign Interventional cae erie. Method A retropective chart review of 156 conecutive eye (139 patient) who underwent placement of an Ahmed Glaucoma Valve (AGV) with a follow-up of ≥3 month wa performed. Main outcome meaure were occurrence and reolution of the HP and intraocular preure (IOP) control. The HP wa defined a IOP > 21 mm Hg during the firt 3 month after urgery. Reolution of the HP wa defined a an IOP < 22 mm Hg and an IOP reduction of 3 mm Hg with the ame or fewer number of glaucoma medication. Reult An HP wa oberved in 88 eye (56%). It occurred after a mean of 5.0 week (median, 4 week; range, 1–13 week) with an average (± tandard deviation) peak IOP of 30.1 (± 7.5) mm Hg. Reolution of the HP occurred in 19 of 68 eye (28%) with available data. Eye with an HP had a higher mean IOP and needed more medication 6 to 12 month after urgery than eye without an HP (17.2 ± 5.6 v 14.3 ± 5.8 mm Hg; P = .012 and 1.7 ± 1.2 v 0.3 ± 0.6 medication; P < .001, repectively). Concluion A hypertenive phae occur frequently after implantation of the AGV. However, it reolve in only a minority of eye. The majority of eye with an HP have no ignificant improvement of IOP control and continue to require the ame number of glaucoma medication a they did during the HP.
