Abstract

Purpose: To evaluate the efficacy and safety of the Ahmed's glaucoma valve implantation in eyes with refractory glaucoma. Materials and Methods: 25 eyes of 25 patients with uncontrolled glaucoma (aphakic/pseudophakic glaucoma in 11, glaucoma following penetrating keratoplasty in 5, epithelial ingrowth in 4, neovascular glaucoma in 4 and silicone glaucoma in 1 eye) despite maximal medical therapy in whom classic trabeculectomy operation's chance of success would be expected to below, were implanted with the Ahmed's glaucoma valve and their postoperative intraocular pressures (IOP), visual acuities, antiglaucomatous medications and complications were evaluated. Results: Success was defined as postoperative IOP levels between 5 and 20 mmHg with or without medication. It was achieved in 21 of 25 eyes (84%). Preoperative mean IOP of 37.3 ± 10.1 mmHg was reduced to 14.6 ± 5.2 mmHg at the end of 8.5 ± 8.9 months follow-up. Avera-ge number of antiglaucomatous medications was decreased from 2.3 ± 0.7 to 0.6 ± 0.7 while best corrected visual acuity did not changed. Flat anterior chamber developed in 3, hyphema in 5, extrusion of the valve and hypotony in 1 eye. Conclusion: Ahmed's glaucoma valve implantation was found to be a safe and effective surgical method in eyes with refractory glaucoma.

Özet

Amaç: Tedaviye dirençli glokom olgularında Ahmed glokom valvi uygulamasının göziçi basıncını düşürmedeki etkinliği ve güvenilirliğinin incelenmesi. Yöntem: Maksimum medikal tedaviye rağmen göziçi basıncı kontrol altına alınamayan ve klasik glokom ameliyatının başarı şansının düşük olduğu düşünülen 25 göze (afakik/pseudofakik glokom 11 göz, keratoplasti sonrası glokom 5 göz, ön kamaraya epitel invazyonu 4 göz, neovasküler glokom 4 göz, silikon glokomu l göz) Ahmed glokom valvi yerleştirilerek olguların postoperatif göz içi basınçları, görme keskinlikleri, kullanılan antiglokomatöz ilaçlar ve kompli-kasyonlar değerlendirildi. Bulgular: Ameliyat sonrası göziçi basıncının ilaçlı ya da ilaçsız olarak 5 ile 20 mmHg ara-sında olması başarı kriteri olarak kabul edildi. 25 gözün 21'inde (%84) cerrahi başarı elde edildi. Ameliyat öncesi 37.3 ± 10.1 mmHg olan göziçi basıncı 8.5 ± 8.9 aylık takip süresi sonunda 14.6 ± 5.2 mmHg'ya düşürüldü. Kullanılan antiglokomatöz ilaç sayısı ameliyat öncesi ortalama 2.3 ± 0.7 iken, postoperatif dönemde 0.6 ± 0.7'ye düştü. Ameliyat sonrası göziçi basıncı ve kullanılan antiglokomatöz ilaç sayısında anlamlı bir azalma olurken görme keskinliğinde anlamlı değişme saptanmadı. Olguların 3'ünde sığ ön kamara, 5'inde hifema, l'inde tüpün atılması ve hipotoni gelişti. Sonuç: Ahmed glokom valvi implantasyonu dirençli glokom olgularında etkin, komplikasyon oranı düşük bir cerrahi yöntem olarak saptandı.
