Abstract

Purpose: To evaluate pars plana capsulectomy (PPC) and anterior vitrectomy (AV) results in posterior capsule opacification (PCO), which can develop after cataract surgery, in pediatric and adult patients in which Nd:YAG laser capsulotomy cannot be performed and/or is not effective because of dense thickening of the posterior capsule. Materials and Methods: Pediatric and adult patients with PPC and AV were included in the study in different groups retrospectively. Results: Nine eyes of 6 pediatric patients and 6 eyes of 6 adults were included in the study. Mean age was 6.1 years (1-11) in the pediatric patients and 59.25 (23-80) in the adults. The mean period of PCO development was 7.6 months in the pediatric patients and 48.2 (2-60) months in the adults. In 7 eyes of 5 pediatric patients who were able to express visual acuity, preoperative best corrected visual acuity (BCVA) was logmar 1.16±0.44 (1-1.6) (Snellen equivalent SE: 0.05-0.1), while it was logmar 0.54±0.26 (0.2-1) (SE: 0.25-0.3) postoperatively. In adults preoperative BCVA was logmar 1.28±0.32 (1-1.6) (SE: finger counting at 3 meters) and it was logmar 0.80±0.2 (0.2-1) (SE: 0.16) postoperatively. At postoperative day one and at 13.6 months mean follow up, a clear optic axis and increase in BCVA were achieved in all eyes. Conclusion: PPC with AV is a preferable management when Nd:YAG laser capsulectomy cannot be performed and/or with the presence of very severe capsule thickening or in cases with cortex reminant on capsule and in cases in which Nd:YAG laser capsulotomy is not effective. We think that performing nearly 5-mm diameter posterior capsulectomy is an important factor in obtaining long period success.

Özet

Amaç: Katarakt operasyonu sonrasında gelişebilen arka kapsül opasifikasyonu (AKO) tedavisinde, Nd:YAG lazer kapsülotomi uygulanamayan ve/veya çok yoğun kapsül kalınlaşması sebebiyle bu tedavinin etkisiz kaldığı, pediatrik ve erişkin tüm olgularda, pars plana kapsülektomi (PPK) ve ön vitrektomi operasyonunun başarısını belirlemek. Gereç ve Yöntem: PPK ve ön vitrektomi ameliyatı yapılmış olan hastaların dosyaları retrospektif olarak incelendi. Pediatrik yaş grubundaki olgular ve erişkinler ayrı gruplarda değerlendirildi. Bulgular: Çalışmaya 6 pediatrik olgunun 9 gözü ve 6 erişkin hastanın 6 gözü alındı. Pediatrik olguların yaş ortalaması 6.1 yıl (1-11), erişkinlerin ise 59.5 yıldı (23-80). AKO oluşumuna kadar geçen ortalama süre, pediatrik yaş grubunda 7.6 ay (4-24), erişkinlerde ise 48.2 aydı (2-60). Vizyon ifadesi olan 5 pediatrik olgunun 7 gözünde, ameliyat öncesi ortalama en iyi düzeltilmiş görme keskinlikliği (EİDGK) logmar 1.16±0.44(1-1.6), (Snellen eşeli karşılığı SE; 0.05-0.1 arası) iken, ameliyat sonrası logmar 0.54±0.26 (0.2-1), (SE; 0.25-0.3 arası)’a yükseldi. Erişkin hastalarda ameliyat öncesi ortalama EİDGK logmar 1.28±0.32 (1-1.6) SE; yaklaşık 3 metreden parmak sayma) iken, ameliyat sonrası logmar 0.80±0.2 (0.2-1), (SE; 0.16)’a çıktı. Tüm gözlerde ameliyat sonrası ilk gün ve 13.6 aylık ortalama takip süresi boyunca saydam bir optik aksla birlikte görme artışı sağlandı. Sonuç: Nd:YAG lazer kapsülotomi uygulanamayan ve/veya kapsül üstünde korteks bakiyesi olan yada diabete bağlı gelişebilen çok yoğun kapsül kalınlaşmasında, Nd:YAG lazer kapsülotomi tedavisinin etkisiz kaldığı tüm olgularda, PPK ve ön vitrektomi tercih edilebilecek bir ameliyattır. Yaklaşık 5 mm çapında geniş olarak yapılacak arka kapsülektominin, uzun dönem başarısında önemli bir etken olduğunu düşünüyoruz.
