Abstract

Purpose: We compared the effectiveness of trabeculectomy with mitomycin-C (MMC) in primary open angle glaucoma in two groups with two different doses. Patients and methods: The first group consisted of 17 eyes of 17 patients that received MMC at a concentration of 0.5 mg/ml for 3 min to the episclera and 2 min under the scleral flap. The second group consisted of 13 eyes of 13 patients that received MMC at a concentration of 0.25 mg/ml for 3 min to the episcleral bed before the flap was dissected. Results: Average follow-up was 20.7 months. Median values for preoperative intraocular pressure was 40 mmHg (range: 30-60) in the first group and 44 mmHg (range: 21-57) in the second group (p=0.93; Mann-Whitney U test). Median postoperative IOP was 4 mmHg (range: 1.1-20) in the first group and 9 mmHg (range: 5-12) in the second group (p= 0.02; Mann-Whitney U test ). Median percentage IOP drop was 89.6 % (range: 58.3-98 %) in the first group and 80 % (range: 59.0-91.2%) in the second group ( p= 0.03; Mann-Whitney U test ). The number of hypotonous eyes was smaller in the second group and this was statistically significant (p=0.02; chi square test ). Conclusion: Reducing the dose and duration of application of mitomycin-C resulted in a lower incidence of hypotonous eyes and adjusting the dose of this antimetabolite to lower levels is necessary for the success and safety of the filtration surgery.

Özet

Amaç: Bu çalışmada primer açık açılı glokom tanısı almış iki hasta grubunda trabekülektomi sırasında iki farklı dozda uygulanan mitomisin-C (MMC) nin etkilerinin karşılaştırılması amaçlanmıştır. Hastalar ve yöntem: Birinci grupta bulunan 17 hastanın 17 gözüne, 0.5 mg/ml konsantrasyonda MMC, 3 dakika süreyle episkleraya ve 2 dak. süreyle skleral flep altına uygulandı. İkinci gruptaki 13 hastanın 13 gözüne ise 0.25 mg/ml konsantrasyonda MMC, 3 dakika süreyle episkleraya uygulandı. Bulgular: Ortalama takip süresi, 20.7 aydı. Preoperatif göz içi basıncı (GİB) değerleri (ortanca ) birinci grupta 40 mmHg (30- 60), ikinci grupta ise 44 mmHg (21-57) idi ( p=0.93; Mann-Whitney U testi). Postoperatif GİB (ortanca), birinci grupta 4 mmHg (1.1-20) ve ikinci grupta 9 mmHg (5-12) idi (p= 0.02; Mann-Whitney U testi ). GİB düşüş yüzdesi (ortanca), birinci grupta 89.6 % (58.3-98 %) ve ikinci grupta 80 % (59.0-91.2%) idi ( p= 0.03; Mann-Whitney U testi ). İkinci grupta hipoton gözlerin sayısı, birinci gruptan anlamlı derecede daha azdı (p=0.02; ki kare testi). Sonuç: Mitomisin-C'nin doz ve uygulama süresinin azaltılması, hipoton göz oluşma insidansını azaltmıştır. Filtrasyon cerrahisinde MMC' nin dozunun düşürülmesi, operasyonun başarısı ve güvenliği açısından gereklidir.
