Abstract

Purpose: To compare the central corneal thickness (CCT) measurements of three different devices. Material and Methods: CCT was measured in one eye of 41 healthy subjects , using the Nidek AL-Scan, Galilei G4 Dual Scheimpflug Analyzer and Cirrus HD-OCT (Cirrus Version 6.0). The agreement between the measurements of three devices was assesed using the one way ANOVA test. To assess the interexaminer reproducibility, two different examiners consecutively obtained CCT measurements in 23 eyes with Nidek AL-Scan, Galilei Dual Scheimpflug Analyzer and Cirrus HD-OCT. Results: Mean±SD values for CCT using the Nidek AL-Scan, Galilei Dual Scheimpflug Analyzer and Cirrus HD-OCT were 541.04±34.91 ?m, 541.56±31.05 ?m, and 541.73±33.83 ?m respectively. There was no statistically significant difference between these three devices at measuring CCT (p=0.98). Intraclass correlation between different observers was fine (>0.9 for each device) and Bland Altman plots of observers' measurements with each device showed good agreement. Conclusions: Nidek AL-Scan, Galilei G4 Dual Scheimpflug Analyzer and Cirrus HD-OCT provide CCT measurements that are in agreement with each other and with the published values for CCT in human subjects. CCT measures from these instruments should be used interchangeably

Özet

Amaç: Bu çalışmada santral korneal kalınlığının (SKK) üç ayrı cihaz ile ölçümleri karşılaştırılmıştır. Gereç ve Yöntem: Çalışmada ortalama yaşı 29.6±7.23 olan 41 hastaya aynı gözlemci tarafından sağ gözlerine Nidek AL-Scan, Galilei G4 Dual Scheimpflug Analyzer ve Cirrus HD-OCT (Cirrus Version 6.0) ile SKK ölçümleri yapıldı. Üç cihaz ile elde edilmiş ölçümler one way ANOVA testi kullanılarak kıyaslandı. Ayrıca 23 hastada farklı iki gözlemci tarafından aynı cihazla SKK ölçümleri yapıldı ve her bir cihaz için gözlemciler arası tekrarlanabilirlik oranı değerlendirildi. Bulgular: Ortalama SKK değerleri Nidek AL-Scan, Galilei Dual Scheimpflug Analyzer ve Cirrus HD-OCT için sırasıyla 541.04±34.91 ?m, 541.56±31.05 ?m ve 541.73±33.83 ?m bulundu. Üç cihazin ölçümleri arasında istatistiksel olarak anlamlı fark tespit edilmedi (p=0.98). Farklı gözlemciler tarafından aynı cihazla yapılan ölçümlerde ise intraklas korelasyon değeri her bir cihaz için 0.9 dan büyük bulundu ve cihazların Bland Altman plotlarında tutarlılık izlendi. Nidek AL-Scan, Galilei G4 Dual Scheimpflug Analyzer and Cirrus HD-OCT provide CCT measurements that are in agreement with each other and with the published values for CCT in human subjects. CCT measures from these instruments should be used interchangeably. Tartışma: Nidek AL-Scan, Galilei G4 Dual Scheimpflug Analyzer ve Cirrus HD-OCT ile ölçülen SKK değerleri istatistiksel olarak birbiriyle ve yayınlanan SKK değerleriyle tutarlı olup, klinik uygulamalarda bu üç alet SKK ölçümü bakımından birbirinin yerine kullanılabilir. Sonuç: Cihazlar SKK ölçümünde birbiri yerine kullanılabilir
