| Title | Long-term results of Ahmed valve implantation in refractory pediatric uveitic glaucoma |
| Purpose | To evaluate the effectiveness and safety of Ahmed valve implantation in children with refractory uveitic glaucoma (UG). |
| Methods | Ahmed valve implantation was performed in 11 children aged from 7 to 17 years (10 eyes) with open-angle or combined form of UG uncompensated on maximum hypotensive regime. Previously all patients underwent on average 2.1 ± 0.9 hypotensive surgeries (predominantly trabeculectomy). 7 eyes were pseudophakic, 2 phakic, 2 aphakic. IOP at the time of surgery was on average 30.5 ± 4.4 mm Hg. Follow-up period ranged from 18 to 40 months (on average 28.9 ± 9.1). |
| Results | Compensation for glaucoma was achieved in 91% cases, among them 3 patients without and 7 patients on hypotensive therapy. Average number of hypotensive drugs after surgery was 1.7 ± 1.5, which was significantly less than before surgery (p = 0.028). At the end of the observation period average IOP was 18.1 ± 5.3 mm Hg (significantly lower than preoperative, p = 0.008). During the surgery in 1 patient mild bleeding from the vessels of the anterior chamber angle after paracentesis was observed. In other cases intervention and postoperative period were uncomplicated. |
| Conclusion | Ahmed valve implantation is an effective and safe method for the surgical treatment of refractory UG in children and can be recommended, if previous antiglaucomatous operations are ineffective. |
