Abstract Details


To evaluate the clinical results of Ahmed Glaucoma Valve (AGV) Flexible Plate implantation in patients with refractory glaucoma secondary to uveitis who do not respond intensive medical therapy and / or conventional filtration surgery.


Istanbul Education and Research Hospital Ophthalmology Department


18 eyes of 16 patients who underwent AGV implantation in the Ophthalmology Department of Istanbul Education and Research Hospital were retrospectively analyzed. Male/Female ratio was 10/6, mean age was 32±14.1. Despite intensive medical treatment, intraocular pressure (IOP) could not be controlled before the AGV (model FP7) implantation. Visual acuity, IOP and the number of antiglaucomatous medications that we recorded pre-operatively were compared with those in the post-operative period. The surgery was deemed successful if the number of antiglaucomatous medications decreased and postoperative IOP levels were kept low without loss of light perception and visual complications.


The mean follow-up period was 19.2±3.4 months. The mean pre-operative IOP value was 32.27±8.41 mmHg. The mean post-operative IOP value was 16.73±7.59 mmHg. The difference between these levels was statistically significant (p?0.05). The mean number of antiglaucomatous medications was 2.80±0.77 pre-operatively and 0.54±0.62 post-operatively. Pre-operative visual acuity remained the same after surgery. In the first post-operative day, there was shallow anterior chamber and hypotony in 2 eyes (11.1%). Anterior chamber was created with viscoelastic agents in these cases. Minimal hyphema was observed in 2 (11.1%) eyes which was resolved spontaneously. Fibrin membrane was seen in 3 eyes (16.7%) which was resorbed with intensive topical corticosteroid treatment. Choroidal detachment developed in 1 eye (5.6%).


The implantation of AGV (model FP7) is an effective surgical procedure in glaucoma secondary to uveitis because it reduces IOP levels and causes minimal complications. FINANCIAL INTEREST: NONE
