Abstract

Objective: The aim of this study is to compare the specular microscopic and demographic features of domestic donors at Beyoglu Eye Training and Research Hospital Eye Bank between years 2013-2016 with the donors imported from Eye Bank Association of America between years 2013-2014. Material and Method: Specular Microscopy and demographic data of the donors acquired from Beyoglu Eye Hospital Eye Bank have been evaluated retrospectively. Results: 629 cornea tissues were excised from 324 donors at Beyoglu Eye Hospital Eye Bank and 836 corneal tissues excised from 530 donors were imported from Eye Bank Association of America. Mean age was 54.26 ± 13.1 (16-78) years for Beyoglu Eye Bank group and 58.54 ± 8.8 (22-70) years for the Eye Bank Association of America donors (p<0.001). 99 donors (30%) were female at the domestic group and 225 were males (70%). Male dominance was also valid for the imported group; 316 (60%) males and 214 females (40%) (p=0.004). Preservation time was 4.1±2.4 (0-17) hours for the Beyoglu Eye Bank donors and 10.6 ± 4.3 (1-20) hours for the imported group (p<0.001). Endothelial cell density was 2659±297 (1124-3436) cells /mm2 for the Beyoglu group and 2486 ± 185 (1481-3205) cells/mm2 for the imported group (p<0.001). When we compared coefficiency of variation; we found similar results for both groups (30.34 ± 7.2 (2-54) vs; 29.8±7.3 (8-57)) respectively (p=0.603). The mean cell area was 381.3±5 (291-890) ?m2 for the Beyoglu group and 404.37 ± 31 (312-675) ?m2 for the other (p<0.01). Hexagonality values were similar for both groups (57.8 ± 6.9 (27-88); 57.0 ± 10.1 (12-262) respectively (p= 0.363). No correlation was detected between age, gender, preservation time and specular microscopic features (respectively; r=0.067, p=0.052; r=0.036, p=0.168; r=-0.036 p=0.168). Conclusions: Imported donors were older and their endothelial cell density was lower than Beyoglu Eye Bank donors. Additionally preservation time was longer in the imported group than Beyoglu Eye Bank donors.

Özet

Amaç: 2013-2016 yılları arasında Beyoğlu Göz Eğitim Araştırma Hastanesi'ne bağlı göz bankası tarafından alınan ve 2013-2014 yıllarıarasında "Eye Bank Association of America" dan ithal edilen donör korneaların demografik ve speküler mikroskobik özelliklerini ortaya koymak ve karşılaştırmak amaçlandı.Gereç ve Yöntem: Beyoğlu Göz Eğitim ve Araştırma Hastanesi'ne bağlı göz bankası kayıtlarından yerli ve ithal donör kornealara ait demografik ve speküler mikroskobik özellikler gruplara ayrılarak retrospektif olarak incelendi. Bulgular: Göz bankasının bağlı olduğu donör kaynaklarından alınan 324 donörün 629 gözü ile ithal olarak alınan 530 donörün 836 gözüdeğerlendirildi. Yaş ortalaması yerli grupta 54,26 ± 13,1 iken ithal grupta 58,54 ± 8,8 idi (p<0,001). Yerli gruptaki donörlerin99'u kadın (%30) iken, 225'i erkekti (%70). İthal grupta ise 214 (%40) kadın, 316 (%60) erkek donör mevcuttu (p=0,004). Prezervasyon süresiyerli grupta 4,1 ± 2,4 saat iken ithal grupta 10,6 ± 4,3 saat idi (p<0,001). Endotel sayıları ortalaması yerli grupta 2659 ± 297 hücre/mm2iken ithal grupta 2486 ± 185 hücre/mm2idi (p<0.001). Değişkenlik katsayısı yerli grupta 30,34 ± 7,2 (254) iken ithal grupta 29,8 ± 7,3 idi ve aralarında anlamlı fark yoktu (p=0,603). Ortalama hücre alanı karşılaştırıldığında yerli grupta381,3 ± 5 ?m2; ithal grupta 404,37 ± 31 ?m2olarak saptandı ve bu fark anlamlı idi (p<0,01). Hekzagonalite oranı (%) iseyerli grupta 57,8 ± 6,9 iken ithal grupta 57,0 ± 10,1 olarak bulundu (p=0,363). Her iki grupta da yaş, cinsiyet ve prezervasyonsüresinin endotel sayısı ile aralarında anlamlı korelasyon saptanmadı (sırasıyla; r:0,067, p=0,052; r:0,036, p=0.168; r= -0,036 p=0,168). Sonuç: İthal donörlerin yerli donörlere göre yaş ortalamasının daha yüksek, endotel sayılarının daha düşük ve prezervasyon sürelerinindaha uzun olduğu saptanmıştır.
