Abstract

Purpose: To investigate intraocular pressure (IOP) control and corneal graft survival in eyes that have undergone mitomycin C trabeculectomy for glaucoma after penetrating keratoplasty. Materials and Methods: Fortyone eyes of 41 patients who underwent trabeculectomy due to glaucoma after penetrating keratoplasty were included in this study. Of the 41 eyes, 24 eyes underwent trabeculectomy with intraoperative mitomycin C at a dosage of 0.4 mg/ml (mitomycin C group) and 17 eyes underwent classic trabeculectomy (trabeculectomy group). The procedure was defined successfull as an IOP of 21 mmHg or lower with or without pressure-lowering medications, and failure as an intraocular pressure of greater than 21 mmHg with medications or need for additional glaucoma surgery. Results: At the last examination, the mean IOP decreased from 30.2 to18.3 mmHg (p=0.001) in mitomycin C group and from 31.1 to 24.9 mmHg (p=0.01) in simple trabeculectomy group. The success rate of IOP control was significantly higher in mitomycin C group (p=0.004). The cumulative probability of graft survival was 66.4% in mitomycin C group and 47% in trabeculectomy group at 3 years (p=0.17). There were no differences in either visual improvement (p=0.39) or decrease (p=0.22) by more than one line after glaucoma surgery between the groups. Conclusion: Mitomycin C trabeculectomy is associated with better results in IOP control. And this increased success rate in IOP control improves the corneal graft survival, although this was not statistically significant.

Özet

Amaç: Penetran keratoplasti sonrası glokom tedavisinde mitomisin C ile uygulanan trabekülektomilerin göz içi basınç (GİB) kontrolü ve greft yaşamı üzerindeki etkisini değerlendirmek. Gereç ve Yöntem: Penetran keratoplasti sonrası glokom tedavisinde trabekülektomi yapılan 41 hastanın 41 gözü çalışmaya dahil edildi. Bunlardan 24 olguda trabekülektomi sırasında 0.4mg/ml dozda mitomisin C uygulandı (mitomisin C grubu) ve 17 olguda ise klasik trabekülektomi (trabekülektomi grubu) yapıldı. Ameliyat sonrası göz içi basıncının ilaçlı veya ilaçsız 21 mmHg ve altında olması durumunda, cerrahi başarılı olarak kabul edildi. Göz içi basıncının ilaçla 21 mmHg üzerinde olması veya ilave glokom cerrahisi gerektirmesi durumunda ise cerrahi başarısız olarak değerlendirildi. Bulgular: Mitomisin C grubunda cerrahi öncesi 30.2 mmHg olan ortalama GİB, son kontrolde 18.3mmHg olarak bulundu (p=0.001). Trabekülektomi grubunda ise ortalama GİB 31.1 mmHg'dan 24.9 mmHg'ya düştü (p=0.01). Mitomisin C grubunda göz içi basınç kontrolündeki başarı anlamlı olarak daha yüksekti (p=0.004). Üçünçü yılda kümülatif korneal greft yaşam oranı mitomisin C grubunda %66.4, trabekülektomi grubunda %47 olarak bulundu (p=0.17). Trabekülektomi cerrahisinden sonra görme keskinliğinde bir sıradan daha fazla artış veya azalış yönünden gruplar arasında anlamlı bir fark yoktu (p=0.39, p=0.22). Sonuç: Penetran keratoplasti sonrası trabekülektomilerde mitomisin C uygulanması, GİB kontrolündeki başarıyı artırmaktadır. Ayrıca GİB kontrolündeki artmış başarı, istatistiksel olarak anlamlı olmasa da korneal greft yaşamını olumlu olarak etkilemektedir.
