Abstract

Purpose: To compare the anterior chamber depth measurements (ACD) obtained by the Galilei Dual-Scheimpflug Analyzer (GSA) and conventional A-scan ultrasound in healthy subjects. Materials and Methods: In this prospective study, ACD measurements of 80 eyes of 43 healthy subjects (30 adults and 13 children; 21 females and 22 males; mean age: 27.86±15.32 years) were respectively measured by GSA (Ziemer Group, Switzerland) and ultrasound. The data was analyzed statistically by the Paired-T test, Bland-Altman plot, and Pearson correlation test to assess the agreement of the measurements. Results: The mean ACD values obtained by GSA and ultrasound were 3.58±0.29 mm and 3.47±0.33 mm, respectively. The mean difference between the ACD measurements obtained by ultrasound and GSA (GSA minus Ultrasound) was 0.11±0.14 mm and the difference between the ACD measurements of these devices was statistically significant (p<0.001). There was high correlation between the ACD measurements of GSA and those of ultrasound (r=0.90; p<0.001). Conclusions: The ACD measurements of GSA and conventional A-scan ultrasound are highly correlated. GSA measures the ACD on average 0.11 mm longer than conventional ultrasound and this difference may be regarded as clinically insignificant.

Özet

Amaç: Galilei Dual-Scheimpflug Analyzer (GSA) ve konvansiyonel A-Tarayıcı ultrason ile sağlıklı bireylerde elde edilen ön kamara derinlik ölçümlerinin karşılaştırılması. Gereç ve Yöntem: Bu prospektif çalışmada, 43 sağlıklı bireyin 80 gözü (30’u yetişkin ve 13’ü çocuk; 21’i kız ve 22’si erkek; ortalama yaş: 27.86±15.32 yıl ) sırasıyla GSA (Ziemer Group, İsviçre) ve ultrason ile ön kamara derinliği için ölçüldü. Ölçümler arasındaki uyumluluk için; veriler Paired-T test, Bland-Altman plot, and Pearson korelasyon testi ile incelendi. Bulgular: GSA ve ultrason ile elde edilen ön kamara derinliği sırasıyla 3.58±0.29 mm and 3.47±0.33 mm idi. Ultrason ve GSA ile elde edilen ön kamara derinlik ölçümleri arasındaki fark (Ultrason eksi GSA) 0.11±0.14 mm iken; bu fark istatistiksel olarak anlamlıydı (p<0.001). GSA ve ultrason ile elde edilen ön kamara derinlik ölçümleri arasında yüksek korelasyon mevcuttu(r=0.90; p<0.001). Sonuç: GSA ve ultrason ile elde edilen ön kamara derinlik ölçümleri birbirleriyle yüksek düzeyde koreledir. GSA ön kamara derinliğini, konvansiyonel ultrasondan ortalama 0.11 mm daha uzun ölçmektedir ve bu fark klinik olarak anlamsız sayılabilir.
