Abstract

Purpose: To determine the prognostic factors of functional outcomes in eyes with severe proliferative diabetic retinopathy (PDR) managed with pars plana vitrectomy (PPV). Materials and Methods: A series of 136 consecutive eyes with severe PDR and non-clearing vitreous hemorrhage (VH) or retinal detachment (RD) that underwent PPV were retrospectively reviewed for prognostic risk factors of surgical outcomes and post-operative vision. Chi-square and logistic regression analysis were used for statistical analysis. Results: Average follow-up was 35 months (range 6-56). A functional outcome (VA>5/200) was achieved in 109 eyes (80.1%) and in 51 of 66 eyes (77.3%) with traction retinal detachment. The VA was improved two lines or more in 79 eyes (58.1%), unchanged in 37 (27.2%), and was worse by 2 lines or more in 20 eyes (14.7%). Complete retinal attachment was observed at the final visit in 122 eyes (89.7%). Predictors of a poor visual outcome were found to be preoperative neovascularization severity (p=0.02), presence of iris neovascularization (RI) (p=0.04), absence of prior pan-retinal photocoagulation (p=0.03), intraoperative fluid/gas exchange (p=0.003), iatrogenic retinotomy (p=0.04), postoperative RI (p=0.0001), recurrent VH (p=0.003), RD requiring PPV and/or buckle surgery (p=0.0001). Logistic regression analysis demonsrated that the significant factors responsible for poor functional outcome to be post-operative RI and RD. Conclusion: Vitreoretinal surgery has been demonstrated to preserve and improve vision in eyes with severe proliferative diabetic retinopathy. Counselling of patients who are to undergo surgery can be performed with a better understanding of the risks of major complications and the likely outcomes.

Özet

Amaç: Pars Plana Vitrektomi (PPV) ile tedavi edilen ciddi Proliferatif Diabetik Retinopatili (PDR) gözlerde görme prognozuna etki eden faktörleri belirlemek. Gereç ve Yöntem: Ciddi PDR’lı ve temizlenmeyen vitreus kanaması veya retina dekolmanı nedeniyle PPV uygulanan ardışık 136 göz serisi, cerrahi sonuçlar ve ameliyat sonrası görmenin prognostik faktörleri yönünden geriye dönük olarak incelendi. İstatistiksel analiz için ki-kare ve logistik regresyon analizi kullanıldı. Bulgular: Ortalama takip süresi 35 ay (6-56 ay) idi. 136 gözün 109’ünde (%80.1), traksiyonel dekolman olan 66 gözün 51’inde (%77.3) fonksiyonel sonuç (VA>5/200) elde edildi. Görme 79 gözde (%58.1) iki sıra veya daha fazla artarken, 37 gözde (%27.2) değişmeden kaldı, 20 gözde (%14.7) iki sıra veya daha fazla görme kaybı oldu. Son muayenede 122 gözde (%89.7) retina tamamen yatışık olarak bulundu. Ameliyat öncesi neovaskülarizasyon şiddeti (p=0.02), iris neovaskülarizyon varlığı (RI) (p=0.04), önceki pan-retinal fotokoagülasyonun yokluğu (p=0.03), ameliyat sırasında gaz/sıvı değişimi (p=0.003), iatrojenik retinotomi (p=0.04), ameliyat sonrası RI (p=0.0001), tekrarlayan vitreus kanaması (p=0.003), PPV ve/veya serklaj gerektiren retina dekolmanının (RD)varlığı (p=0.0001) kötü görme için ön görülen faktörler olarak bulundu. Logistik regresyon analizinde ise ameliyat sonrası RI ve RD varlığı kötü fonksiyonel sonuçtan sorumlu önemli faktörler olarak bulundu. Sonuç: Ciddi PDR’lı gözlerde vitreoretinal cerrahi ile görmenin korunduğu ve artırıldığı gösterilmektedir. Başlıca komplikasyonların risklerini ve muhtemel sonuçlarını daha iyi anlayarak, cerrahi uygulanacak hastalara danışmanlık yapılabilir.
