Abstract

Objective: To evaluate the results of corneal cross-link- ing with UV-A/riboflavin in patients with progressive kera- toconus. Methods: Forty-seven eyes of 30 patients with progres- sive keratoconus (16 female, 14 male) were included in the study. Uncorrected and the best corrected distance visual acuities, biomicroscopic findings, intraocular pres- sure measurements, fundoscopic findings, pachymetric measurements and corneal topography parameters were recorded for each patient. Results: The mean age of the patients was 18.3±5.34 (range: 8-31) years and the mean follow-up duration was 7±2.4 (range: 3-12) months. Following the procedure, the mean decrease in K1, K2, Kav, spherical and cylindri- cal values were 0.77 D, 0.85 D, 0.80 D, 0.50 D and 0.74 D, respectively (p<0.05). There were no cases with de- crease in visual acuity and significant complication during or after the treatment. Conclusion: Cross-linking with riboflavin/UV-A in patients with progressive keratoconus is an effective procedure. In addition, the preservation of visual acuity and not seen a significant complication indicate that a safe metod. How- ever, large prospective randomized controlled studies are needed to evaluate the long-term effects of this treatment.

Özet

Amaç: Keratokonus kliniğinde ilerleme saptanan olgular- da, UV-A/riboflavin ile korneal kollajen çapraz bağlama yönteminin sonuçlarının değerlendirilmesi. Yöntemler: İlerleyici keratokonusu olan 30 olgunun (16 kadın, 14 erkek) 47 gözü çalışmaya dahil edildi. Tüm ol- guların uygulama öncesi ve sonrasında, düzeltilmemiş ve düzeltilmiş en iyi görme keskinleri, biyomikroskopik bul- guları, göz içi basınç ölçümleri, fundus bulguları, pakimet- ri değerleri ve kornea topografi parametreleri kaydedildi. Bulgular: Olguların ortalama yaşı 18,3 yıl (8-31) ve orta- lama takip süresi 7±2,4 ay (3-12) idi. Uygulama sonrasın- daki takipler sonucunda ortalama K1, K2, Kav, sferik ve silindirik değerlerde sırasıyla; 0,77 diyoptri (D), 0,85 D, 0,80 D, 0,50 D ve 0,74 D azalma saptandı (p<0,05). Ol- guların görme keskinliklerinde azalma saptanmadı, uygu- lama esnasında ve sonrasında önemli bir komplikasyon görülmedi. Sonuç: İlerleyici keratokonus hastalarında yapılan UV-A/ Riboflavin ile kollajen çapraz bağlama yöntemi etkin bir prosedürdür. Ayrıca görme keskinliklerinin korunması ve önemli bir komplikasyonun görülmemesi güvenli bir metot olduğunu göstermektedir. Ancak bu tedavinin uzun dönem sonuçlarını değerlendirmek için daha geniş serili, kontrollü, prospektif ve randomize klinik çalışmalara ihtiyaç duyulmaktadır
