Abstract

Purpose: To investigate the effects of type of cataract surgery, preoperative retinopathy level, and duration of diabetes on retinopathy progression, and visual outcomes after phacoemulsification or extracapsular cataract extraction in patients with diabetes mellitus in a prospective and case controlled study. Materials and Methods: A clinical and angiographie review of 54 diabetic patients who underwent two distinct types of cataract surgery was prospectively performed in two groups during a 9-month period. There were 20 diabetic patients who underwent phacoemulsification surgery in group 1, 34 diabetic patients who underwent extracapsular cataract surgery in group 2. Cataract surgery was performed in one single eye of each patient while fellow eyes were used as controls. Results: Progression rate of diabetic retinopathy was 25 % in eyes which underwent phacoemulsification, 23.5% in eyes with extracapsular cataract extraction and the difference was not significant (p>0.05). The difference between operated and fellow eyes in terms of progression of retinopathy was not significant in patients with phacoemulsification (p>0.05), while progression rate was significantly higher in the operated eyes in extracapsular extraction group (p<0.05). Duration of diabetes was longer in eyes with progression independent of the surgical technique (p<0.05). Significant visual improvement was achieved in both operated groups, however improvement was to a lesser extent in group 2 (61.8%, p<0.05). Conclusion: In diabetic patients who underwent cataract surgery progression of retinopathy is faster than the natural course of the disease in unoperated eyes. Progression of retinopathy is more frequent in the operated eyes of patients who underwent extracapsular cataract extraction. Higher duration of diabetes, preoperative retinopathy and postoperative progression are factors that negatively influence the visual outcome. Phacoemulsification technique might be more favourable in terms of visual improvement in diabetic patients.

Özet

Amaç: Ekstrakapsüler veya fakoemül-sifikasyon yöntemlerinden biri ile katarakt ekstraksiyonu . yapılan diyabetli hastalarda uygulanan cerrahi tipinin, ameliyat öncesi retfnopati evresinin ve diyabet süresinin Diyabetik retinopatinin ilerlemesi ve görsel sonuçlar üzerine etkilerinin ileriye dönük ve kontrollü olarak incelenmesi, Gereç ve Yöntem: Katarakt ekstraksiyonu yapılan ve önceden belirlenen kriterlere uyan, 54 diyabetli olgu iki gruba ayrılarak dokuz ay boyunca klinik ve anjiyografik olarak takip edildi. Grup 1'de fakoemülsifikasyon yapılan 20 diyabetli olgu; grup . 2'de ekstrakapsüler ekstraksiyon yapılan 34 diyabetli olgu incelendi. Tüm olguların bir gözüne katarakt cerrahisi uygulanırken, ameliyat olmayan diğer gözleri kontrol olarak alındı. Bulgular: Diyabetik retinopatinin ilerleme sıklığı, Fakoemülsifikasyon cerrahisi uygulanan gözlerde %25, ekstrakapsüler katarakt cerrahisi uygulanan gözlerde %23.5 olarak bulundu ve aradaki fark anlamlı değildi (p>0.05). Ancak, fakoemülsifikasyon cerrahisi uygulanan grupta, diyabetik retinopatinin ilerleme sıklığı yönünden ameliyat olan gözlerle, ameliyat olmayan gözler arasında anlarrjlı fark saptanmazken (p>0.05), ekstrakapsüler katarakt cerrahisi uygulanan grupta, diyabetik retinopatide ilerleme, ameliyat olan gözlerde, olmayanlara göre anlamlı olarak daha yüksek bulundu (p<0.05). Her iki cerrahi yöntemde de retinopatinin ilerlediği olgularda diyabetin süresi daha uzundu (p<0.05). Her iki grupta da ameliyat sonrasında anlamlı görme artışı sağlanmasına rağmen, en düşük görsel kazanç oranı grup 2'de elde edildi ( %61.8, p<0.05).Sonuç: Diyabetli hastalarda katarakt ameliyatı sonrasında retinopatinin ilerlemesi, hastalığın doğal seyrine göre daha hızlı gelişmektedir. Ekstrakapsüler katarakt cerrahisi uygulanan grupta, diyabetik retinopatide ilerleme ameliyat olan gözlerde ameliyatsız gözlere göre daha sık gelişmektedir. Uzun süreli diyabet, diyabetik retinopatinin ameliyat öncesinde mevcut olması ve ameliyat sonrasında ilerleme göstermesi ameliyat sonrası görsel başarıyı olumsuz etkileyen faktörlerdir. Bu olgularda fakoemülsifikasyon yönteminin seçilmesi ameliyat sonrasında beklenen görsel başarıyı olumlu yönde etkileyebilir.
