Abstract

Corneal ectasia or recurrent keratoconus after penetrating keratoplasty is rare, and few case reports exist in the literature concerning this condition. Computerized corneal topography is quite useful to identify and manage this disorder. Management consists of several methods ranging from spectacle and contact lens correction to repeated penetrating keratoplasty. Clinical and computerized topography findings of two patients with keratectasia following penetrating keratoplasty are presented in this article. Two healthy 45-year-old and 25-year-old male patients complained of decreased visual acuity following penetrating keratoplasty. Clinical and topographical data were consistent with recurrence of corneal ectasia. After repeated penetrating keratoplasty, best-corrected distance Snellen visual acuity of 0.7 was obtained in the 45-year-old patient. The other patient underwent collagen cross linking, received antiglaucomatous therapy, and his visual acuity reached 0.5. During the follow-up period, ectasia progression did not occur.

Özet

Penetran keratoplasti sonrası kornea ektazisi veya keratokonus nüksü nadir görülen bir tablodur ve bu tablo ile ilgili literatürde az sayıda vaka sunuları vardır. Bilgisayarlı topografi kullanımı hastalığın tanı ve tedavisinde oldukça yararlıdır. Tedavide gözlük ve kontakt lens kullanımından, tekrarlanan penetran keratoplastiye kadar birçok yöntem yer alır. Bu makalede penetran keratoplasti sonrası ektazi gelişen iki vakanın klinik ve bilgisayarlı topografi bulguları sunuldu. 45 ve 25 yaşında sağlıklı iki erkek hasta penetran keratoplasti sonrası görme keskinliklerinde azalmadan yakınmaktaydı. Oftalmolojik ve topografi bulguları kornea ektazisi nüksü ile uyumluydu. 45 yaşındaki hasta rekeratoplasti sonrası 0,7 Snellen sırası düzeltilmiş görme keskinliği elde etti. Diğer hastaya kollajen çapraz bağ tedavisi uygulandı, antiglokomatöz tedavi verildi ve görme keskinliği 0,5’e ulaştı. Takip süreleri boyunca ektazide ilerleme olmadı.
