Abstract

Purpose: To compare the effect of the panretinal laser photocoagulation treatments performed using argon and dye yellow lasers in diabetic retinopathy. Materials and Methods: Both eyes of 32 type 2 diabetes patients who were diagnosed as early proliferative diabetic retinopathy were included in the study. Each patient underwent panretinal laser photocoagulation treatment for a total of three sessions using argon green laser for one eye and the dye yellow laser for the fellow eye. Each eye underwent a total of 1800-2000 laser burns with a spot size of 500 microns. Complete ophthalmological examinations of each eye were performed before and 1 and 3 months following the laser treatment. Color vision and visual field analysis of the subjects were repeated 3 months after the laser treatment. Statistical analysis of the study was performed using Mann Whitney U test, Wilcoxon signed rank test and ANOVA for repeated measures. Results: There were no significant difference between both laser therapy types in terms of neovascularization regression and the visual acuity (p>0.05). No significant intergroup difference in visual field mean sensitivity were noted before(p:0.06) and after (p:0.13) the laser treatment. Pain scores were found to be significantly higher in eyes treated with dye yellow laser (p:0.001). Conclusion: There have been no significant difference between panretinal laser photocoagulation treatments performed using either dye yellow or argon green laser in terms of visual acuity and the functional visual field sensitivity. As dye yellow laser is found to be more painful, panretinal laser photocoagulation treatments using argon laser seems to be more appropriate in treatment of patients with proliferative diabetic retinopathy.

Özet

Amaç: Proliferatif diabetik retinopatili hastalarda argon yeşil ve dye sarı laserle yapılan pan retinal fotokoagulasyon tedavi etkinliklerinin karşılaştırılması. Gereç ve Yöntem: Her iki gözüne erken proliferatif diabetik retinopati tanıları konulmuş 32 tip 2 diabet hastası çalışma kapsamına alındı. Her hastanın bir gözüne argon yeşil ve diğer gözlerine ise dye sarı lazer kullanılarak üçer seansta panretinal lazer fotokoagulasyon tedavileri tamamlandı. Her göze 500 mikron spot çapında toplam 1800-2000 şut lazer uygulandı. Hastaların her iki gözlerinin lazer tedavi öncesi ve lazer tedavisinden 1 ay ve 3 ay sonra tam oftalmolojik muayeneleri gerçekleştirildi. Hastaların lazer öncesi ve lazer sonrası 3. ay muayenelerinde renkli görme ve görme alanı testleri tekrarlandı. Çalışmanın istatistiksel analizinde Mann Whitney U testi, Wilcoxon signed rank testi ve tekrarlı ölçümlerde varyans analizi kullanıldı. Bulgular: Her iki lazer tedavileri arasında neovaskularizasyon regresyonu ve görme keskinliğine etkileri bakımından anlamlı bir farklılık saptanmadı (p>0.05). Tedavi öncesi (p:0.06) ve sonrası (p:0.13) görme alanı ortalama eşik değerleri arasında gruplararası anlamlı farklılık bulunmadı. Ağrı skorları dye sarı laserle tedavi edilen gözlerde anlamlı olarak fazla bulundu (p:0.001). Sonuç: Dye sarı ve argon yeşili ile panretinal lazer fotokoagulasyon tedavisi uygulanan gözler arasında tedavi sonrası görme keskinliği ve fonksiyonel görme alanı eşik değerlerine etkileri bakımından anlamlı farklılıklar izlenmemektedir. Dye sarı laserle yapılan işlemlerin ağrılı olması proliferatif diabetik retinopati tedavisinde argon lazer tedavilerin daha öncelikli tercih edilmesini sağlamaktadır.
