Özet
Amaç: Optik koherens tomografi (OKT) ile değerlendirilen retina sinir lifi kalınlığının (RNFL) katarakt cerrahisi öncesi ve sonrası değişiminin incelenmesi. Gereç ve Yöntem: Çalışmamıza retina sinir lifi kalınlığını etkileyebilecek herhangi bir retina, optik sinir ve kornea hastalığı olmayan, komplikasyonsuz katarakt cerrahisi uygulanmış 44 hastanın 44 gözü alındı. Tüm hastalara katarakt cerrahisinden bir gün önce ve cerrahiden bir ay sonra spektral domain OKT ile RNFL ölçümü yapıldı. Katarakt düzeyleri Lens Opacities Classification System III (LOCS III) sistemine göre derecelendirildi. Bulgular: Hastaların yaş ortalaması 62,68±9,46 idi. Gözlerden 23’ü sağ (%52,3) ve 21’i sol (%47,7) idi. Cerrahi öncesi ortalama en iyi düzeltilmiş görme keskinliği 0,29±0,12, cerrahi sonrası birinci ayda en iyi düzeltilmiş görme keskinliği 0,93±0,12 olarak saptandı. Ortalama RNFL kalınlığı cerrahi öncesi 89,43±23,0 ? iken cerrahi sonrası 106,57±12,5 ? idi. Aradaki fark istatiksel olarak anlamlıydı. Ortalama görüntü kalitesi cerrahi öncesi %44,53 iken cerrahi sonrası %63,51 idi. Aradaki fark istatiksel olarak yine anlamlıydı. Sonuç: Katarakt varlığı OKT’de görüntü kalitesini etkilemektedir ve RNFL ölçümlerinin daha düşük çıkmasına yol açmaktadır. Katarakt cerrahisi OKT’de görüntü kalitesini arttırarak RNFL ölçümlerinin daha sağlıklı elde edilmesini sağlar. (Turk J Ophthalmol 2014; 44: 284-7)
Objectives: To evaluate the retinal nerve fiber layer (RNFL) thickness by optical coherence tomography (OCT) before and after cataract surgery. Materials and Methods: In our study, we included 44 eyes of 44 patients who underwent uncomplicated cataract surgery and had no preexisting pathology involving the retina, optic nerve, or cornea. All patients were scanned by OCT for RNFL measurements 1 day before and 1 month after cataract surgery. The grading of cataract was based on the Lens Opacities Classification System III (LOCS III). Results: The mean age of patients was 62.68±9.46 years. The mean best-corrected visual acuity (BCVA) was 0.29±0.12 preoperatively and 0.93±0.12 at postoperative one month. The mean RNFL thickness preoperatively was 89.43±23.0 μ and postoperatively was 106.57±12.5 μ. The difference was statistically significant. The mean image quality preoperatively was 44.53% and postoperatively was 63.51%. The difference was also statistically significant. Conclusion: The presence of cataract may affect the image quality of OCT leading to lower RNFL thickness values than expected. Cataract surgery increases the image quality of OCT and allows accurate RNFL measurements. (Turk J Ophthalmol 2014; 44: 284-7)
