Abstract

Purpose: To investigate the incidence, occurrence period, progression and risk factors for intraocular pressure (IOP) elevation after Penetrating Keratoplasty (PK) as well as its management and treatment results. Materials and Methods: Data of 342 eyes who had PK between 2003-2014 with a regular follow-up and IOP measurements of at least 1 year were reviewed retrospectively. 102 eyes with a rise in IOP exceeding 21 mmHg during follow-up were spared and analysed. Results: IOP increase occurred in 29.8% of the patients. Mean time of occurrence was 16.8±13.3 post-operative week. Mean age was 60.6±17.6 . Number of patients under age 40 was 30 (27.0%). Mean preoperative IOP of 14.6±2.9 mmHg increased to 25.7±4.1 mmHg. Combined procedures during PK had no significant effect on postoperative pressure elevation (p=0.076, Chi-square test). Age, gender and trephine diameters were not significant risk factors. However, pseudophakic bullous keratopathy with an incidence of 48.1% was found as the most significant risk factor (p=0.002, Ki-kare testi). IOP was controlled with one topical agent in 44 eyes (43.1%), with fixed combination in 51 eyes (50.0%), in 6 eyes (5.9%) which were resistant to medical therapy trabeculectomy was performed in eye (1.0%) Ahmed Glaucoma Device was implanted.Conclusion: IOP elevation is a serious complication after PK which is not rare. Especially pseudophakic bullous keratopathy is a significant risk factor. In order to protect graft clarity and optic disc functions, IOP should be monitored closely after PK and aggressively treated if found to be high.

Özet

Amaç: Penetran keratoplasti (PK) sonrası göz içi basıncı GİB yüksekliği sıklığını, başlangıç zamanını, gelişmesini etkileyen faktörleri, tedavi yaklaşımlarını ve sonuçlarını araştırmaktır.Gereç ve Yöntem: 2003-2014 arasında PK yapılan, en az 1 yıl düzenli izlem ve GİB ölçümleri yapılmış olan 342 hastanın verileri retrospektif olarak incelendi. İzlem sırasında GİB değeri 21 mmHg'nın üzerine çıkan 102 hastanın 102 gözü ayrılarak değerlendirildi.Bulgular: GİB yüksekliği olguların %29.8'inde görüldü. Ortalama 16.8±13.3 postoperatif haftada gelişti. Yaş ortalamaları 60.6±17.6 olup, 40 yaş altındaki hasta sayısı 30 (%27.0) idi. Preoperatif ortalama GİB 14.6±2.9 mmHg iken, postoperatif GİB ortalaması 25.7±4.1 mmHg'ya yükseldi. Ek cerrahi girişim, PK sonrası GİB yüksekliği açısından, istatistiksel olarak anlamlı bir risk oluşturmadığı görüldü (p=0.076, ki-kare testi). Yaş, cinsiyet ve trepan çapları da anlamlı bir fark göstermedi. Ancak büllöz keratopati %48.1 en belirgin risk grubunu oluşturmaktaydı (p=0.002, Ki-kare testi). Hastaların 44'sinde (%43.1) tek ilaç, 51'inde (%50.0) kombine ilaç tedavisi ile GİB'de yeterli düşüş sağlanırken, medikal tedaviye cevap vermeyen 6 (%5.9) olguya trabekülektomi ve 1 (%1.0) olguya Ahmed Glokom Valvi implantasyonu yapıldı. Sonuç: GİB yüksekliği PK sonrası sık görülen, ciddi bir komplikasyondur. Psödofakik büllöz keratopati olguları daha büyük risk taşımaktadır. Ameliyat sonrası GİB'nın yakından izlenmesi, yükselme saptandığında greft saydamlığını ve optik disk işlevlerini korumak için enerjik bir biçimde tedavi edilmesi gerekmektedir.
