Abstract

Purpose: To evaluate the efficacy of needling and subconjunctival 5-fluorouracil (SC5-FU) application in bleb failure after trabeculectomy. Material and Method: 29 eyes of 29 patients with bleb failure were included in the study. Needling and SC5-FU injection were applied to all eyes between 3 weeks to 4 years after trabeculectomy. SC5-FU injections were repeated 3 to 6 times with regard to IOP and bleb vascularization (BV) levels. Patients were followed between 14 to 26 months ( median 17 months). In control examinations IOP, BV and complications were noted. Results: BV was grade 4 in 11 eyes and grade 3 in 18 eyes before procedure while it was grade 1 in 7 eyes, grade 2 in 16 eyes and grade 3 in 6 eyes after procedure. IOP was between 26 to 41 mmHg (median 32.0 mmHg) before procedure while it was between 12 to 29 mmHg (median18.0 mmHg) after procedure. The differences between the pre-procedure and after procedure IOP and BV levels was found to be statistically significant (p<0.05). Success was not achieved in 9 (31%) patients who had high risk for bleb failure after trabeculectomy. Total success rate was 69%. Complications included; subconjunctival hemorrhage in 6 (20%) eyes, choroidal detachment in 4 (14%) eyes, shallow anterior chamber in 3 (10%) eyes, corneal punctuate epitheliopathy in 2 (7%) eyes and hypotony papillopathy in 1 (3.5%) eye. Conclusion: Needling and SC5-FU application is an effective procedure in decreasing the IOP and regressing the BV in bleb failure after trabeculectomy. The procedure is less successful in high risk glaucoma patients in which intraoperative adjuvant use of antimetabolite is indicated.

Özet

Amaç: Trabekülektomi sonrası bleb yetmezliğinde, iğneleme ve konjonktiva altı 5-florourasil (KA 5-FU) uygulamasının etkinliğini araştırmak. Gereç ve Yöntem: Bleb yetmezliği olan 29 hastanın 29 gözü çalışmaya alındı. Bütün gözlere trabekülektomiden 3 hafta ile 4 yıl sonra iğneleme ve KA5-FU enjeksiyonu yapıldı. Konjonktiva altı 5-FU enjeksiyonları göz içi basıncı (GİB) ve bleb damarlanması dikkate alınarak iğnelemeden sonra 3 ile 6 kez tekrar edildi. Hastalar 14 ile 26 ay (medyan 17 ay) süreyle takip edildi. Kontrol muayenelerinde GİB, bleb damarlanması ve komplikasyonlar not edildi. Bulgular: İşlem öncesi bleb damarlanması, 11 gözde evre 4, 18 gözde evre 3 iken işlem sonrası 7 gözde evre 1, 16 gözde evre 2, 6 gözde evre 3 idi. İşlem öncesi GİB 26 ile 41 mmHg (medyan 32.0 mmHg ) arasında iken, işlem sonrası 12 ile 29 mmHg (medyan 18.0 mmHg ) arasında idi. İşlem öncesi ve işlem sonrası bleb damarlanması ve GİB değerleri arasındaki fark istatistiksel olarak anlamlı bulundu (p<0.05). En son kontrolde toplam başarı oranı % 69 idi. Glokom ameliyatları açısından yüksek risk özellikleri taşıyan 9 (%31) olguda başarı sağlanamadı. Komplikasyon olarak 6 (%20) gözde konjonktiva altı kanama, 4 (%14) gözde koroid dekolmanı, 3 (%10)gözde ön kamara darlığı, 1 (%3.5)gözde hipotoniye bağlı papil ödemi, 2 (%7)gözde korneada punktat epitelyopati gelişti. Sonuç: Trabekülektomi sonrası gelişen bleb yetmezliğinde, iğneleme ve KA5-FU uygulaması GİB düşürülmesinde ve bleb damarlanmasının gerilemesinde etkili bir işlemdir. İşlemin trabekülektomi sırasında yardımcı antimetabolit kullanım endikasyonu bulunan, yüksek riskli glokom hastalarında başarı oranı düşüktür.
