Abstract

Purpose: To evaluate patients prediagnosed with capsular block syndrome (CBS) using slit-lamp adapted anterior segment optical coherencetomography (SL-OCT) prospectively.Materials and Methods: The eyes of the patients with decreased vision following phacoemulsifi cation and intraocular lens (IOL) implantationprediagnosed as capsular block syndrome were included. Following ophthalmological examination with pupillary dilation, SL-OCT imagingwas performed.Results: The study included 17 eyes of 17 cases with late onset CBS. The mean period of time between cataract operation and CBS diagnosiswas 66.5± 31.6 months ( range 5 to 120 months). The interspace between posterior surface of the IOL and posterior capsule was hyporefl ectivein six cases and hyperrefl ective in other cases. The mean posterior displacement of posterior capsule was 1.02 ± 0.74 mm (ran ge 0.35 to 2.17mm) at the deepest location. Except for three cases all were treated with Neodymium:YAG (Nd:Y AG) laser posterior capsulotomy.Conclusion: Late-onset CBS can be seen years after phacoemulsifi cation surgery and is thought to be occurred by the liquefi ed retained corticalmaterial. Also, this condition may be misdiagnosed as IOL opacifi cation. SL-OCT is a useful and supportive method in the demonstration anddifferential diagnosis of CBS.

Özet

Amaç: Kapsüler Blok Sendromu (KBS) ön tanısı konulan olguların biyomikroskop ile birleştirilmiş Ön Segment Optik Koherens Tomografi si (ÖS-OKT) ile prospektif olarak değerlendirilmesi. Gereç ve Yöntemler: Fakoemülsifi kasyon ve göz içi lensi (GİL) implantasyonu sonrası görmede azalması olan, KBS ön tanısı koyulan olan hastalar çalışmaya dahil edildi. Pupilla dilatasyonu öncesi ve sonrası yapılan oftalmik muayene ardından ÖS-OKT ile ön segment görüntülemesi yapıldı. Bulgular: Çalışma geç başlangıçlı KBS olan 17 hastayı kapsamaktadır. Katarakt ameliyatı ile KBS tanısı arasında geçen süre ortalama 66.5 ± 31.6 ay (dağılım 5 ve 120 ay) idi. Arka kapsülün posteriorda yer değişimi en derin noktada 1.02 ± 0.74 mm (dağılım 0.35 ve 2.17 mm) olarak ölçüldü. GİL arka yüzeyi ve arka kapsül arasındaki boşluk 6 olguda hiporefl ektif, diğerlerinde hiperrefl ektif olarak izlendi. Üç vaka dışında tamamına Neodymium:YAG laser arka kapsulotomi uygulandı. Sonuç: Geç dönem KBS, fakoemülsifi kasyon ameliyatından yıllar sonra görülebilmekte ve likefi ye korteks materyaline bağlı olduğu düşünülmektedir. Aynı zamanda, bu durum GİL’in opaklaşması olarak yanlış tanı alabilir. ÖS-OKT, KBS’nin gösterilmesi ve ayırıcı tanısında faydalı destekleyici bir görüntüleme yöntemidir.
