Abstract

A 31-year-old male patient was admitted with the complaint of decreased vision in both eyes. He underwent multiple pars plana vitrectomy and silicone oil injection operations due to bilateral retina detachment after rocket projectile explosion in his hands at the age of 15. The right eye was pre-phthisical after choroidal hemorrhage that occurred during combined silicone oil extraction and penetrating keratoplasty. The aphakic and vitrectomized left eye had corneal conjunctivalisation of seven dials, deep and superficial stromal neovascularization and history of immunological graft rejection. As the estimated success rate for repeat penetrating keratoplasty was low, Boston type 1 keratoprosthesis surgery was performed. Postoperatively, visual acuity was 0.2 Snellen lines. Macular scar and optic nerve atrophy limited further visual gain. In this study, we aimed to review the current literature about Boston type keratoprosthesis surgery, which should be evaluated as an alternative when conventional penetrating keratoplasty success is deemed to be low.

Özet

Otuz bir yaşında erkek hasta kliniğimize her iki gözle az görme şikayeti ile başvurdu. 15 yaşında iken elinde roket mermisi patlaması sonucu bilateral retina dekolmanı nedeniyle tekrarlayan pars plana vitrektomi ve silikon yağı enjeksiyonu operasyonları geçirmişti. Sağ göz, kombine silikon alınması ve penetran keratoplasti operasyonu sırasında koroid hemorajisi gelişmesi nedeniyle prefitizikdi. Afak, vitrektomize olan sol gözde limbal kök hücre yetmezliği nedeniyle yedi saat kadranı boyunca korneada konjunktivalizasyon, derin ve yüzeyel stromal neovaskülarizasyon ve immunolojik kornea nakli reddi hikayesi mevcuttu. En iyi düzeltilmiş görme keskinliği 1 metreden parmak sayma düzeyindeydi. Tekrar penetran keratoplasti başarı şansı düşük olarak değerlendirilen hastaya Boston tip 1 keratoprotez uygulaması yapıldı. Postoperatif dönemde görme keskinliği 0.2 Snellen sırası seviyesine ulaştı. Makulada var olan skar ve optik sinir atrofisi, daha ileri görme artışını kısıtlıyordu. Bu çalışmada konvansiyonel penetran keratoplasti başarı şansı düşük olarak değerlendirilen gözlerde bir alternatif olarak değerlendirilmesi gereken Boston tipi keratoprotez uygulaması hakkında güncel literatürü derlemeyi amaçladık.
