Abstract

Purpose: To investigate the effectiveness of subconjunctival low dose 5-fluorouracil injection (5-FU) in the management of bleb failure after trabeculectomy. Materials and Methods: Forty eyes of 40 patients with bleb failure after trabeculectomy were included in this study. Repeated doses of 5mg of 5-fluorouracil (5-FU) were injected subconjunctivally in eyes with bleb failure after filtering surgery. The success was defined as an intraocular pressure (IOP) of &#8804;21 mmHg with or without medications. Intraocular pressure, the number of eyes using antiglaucomatous medications, frequency of 5- FU injection, variations of bleb appearance and complications were evaluated prospectively during the follow-up period. Results: Primary open angle glaucoma in 12 eyes (30%), neovascular glaucoma in 10 eyes (25%), narrow angle glaucoma in 3 eyes (7.5%) and secondary glaucoma in 15 eyes (37.5%) were detected. When a decision of applying 5-FU injection was reached, mean IOP was 26.2±7.1mmHg. The mean IOP was 17.0±9.0 mmHg at the last follow-up examination. There was statistically significant difference between the pre-treatment and post-treatment IOP (p<0.001). 5-FU application was more successful in patients with primary glaucoma (p<0.05). Overall rate was 91.6% at 3 months, 85.7% at 6 months, 80% at 12 months and 63.6 %at 18 months. Follow-up time was 3-18 months. Punctate epiteliopathy in 9 (22.5%) eyes and corneal ulcers in 5 (12.5%) eyes were observed during follow-up period. Conclusions: Low dose 5-FU application appears to improve bleb function in patients with bleb failure after trabeculectomy. Procedure is more successful in patients with primary glaucoma. The modified administration of 5-FU can result in fewer corneal complications.

Özet

Amaç: Trabekülektomi sonrası gelişen blep yetmezliğinin tedavisinde konjonktiva altı düşük doz 5-florourasil enjeksiyonunun (5- FU) etkinliğinin araştırılması. Gereç ve Yöntem: Trabekülektomi sonrası blep yetmezliği gelişen 40 olgunun 40 gözü çalışma kapsamına alındı. Filtrasyon bölgesinin 4 mm gerisine konjonktiva altına 5mg/0.1ml 5-FU enjeksiyonu yapıldı. Göz içi basıncının (GİB) ilaçlarla veya ilaçsız 21 mmHg altında olması başarı olarak tanımlandı. Takip süresi esnasında GİB, antiglokömatöz ilaç kullanan göz sayısı, 5-FU enjeksiyonunun yapılma sıklığı, blep görünümündeki değişiklikler ve görülen komplikasyonlar incelendi. Bulgular: Çalışmaya alınan gözlerin 12’sinde (%30) primer açık açılı glokom, 10’unda (%25) neovasküler glokom, 3’ünde (%7.5) dar açılı glokom, 15’inde (%37.5) sekonder glokom tespit edildi. Takiplerde GİB, 5-FU enjeksiyonu yapılmaya karar verildiğinde ortalama 26.2±7.1 mmHg’ye çıkmıştı. En son kontroldeki ortalama GİB 17.0±9.0 mmHg idi. Enjeksiyon öncesi ve en son GİB değerleri arasında istatistiksel olarak anlamlı bir düşüş saptandı (p<0.001). Uygulama primer glokom olgularında, ikincil glokomu olan olgulara göre daha başarılı bulundu (p<0.05). Toplam başarı oranları; 3 aylık takip sonunda %91.6, 6 aylık takip sonunda %85.7, 12 aylık takip sonunda %80, 18 aylık takip sonunda %63.6 olarak tespit edildi. Takip süresi en az 3 ay, en çok 18 aydı. Takip esnasında 9 (%22.5) gözde punktat epitelyopati, 5 (%12.5) gözde kornea ülseri gelişti. Sonuç: Trabekülektomi sonrasında blep yetmezliğinin geliştiği ve GİB’nın arttığı hastalarda konjonktiva altı düşük doz 5-FU uygulaması etkili bir şekilde GİB kontrolü sağlamaktadır. Başarı primer glokom olgularında daha yüksektir.Uygulamanın aralıklı yapılması kornea komplikasyonlarını azaltacaktır.
