Özet
Amaç: IOLMaster ve A-tarayıcı ultrason ile yapılan ön kamara derinliği (ÖKD) ve aksiyel uzunluk (AU) ölçümlerinin karşılaştırılması.Gereç ve Yöntem: Çalışmaya 60 hastanın (29 erkek, 31 kadın) 60 sağ gözü dahil edildi. İlk olarak IOLMaster (Carl Zeiss Meditec, Jena, Germany) ile ÖKD ve AU ölçümleri, takiben A-tarayıcı ultrason (SW-1000, Suowei Co., Tianjin, China) ile aynı ölçümler yapıldı. İki yöntemle elde edilen ölçümler arası farklılık paired t testi ile, korelasyon ise Pearson korelasyon analizi ile değerlendirildi.Bulgular: Hastaların ortalama yaşı 24.6±4.90 yıl idi. IOLMaster ile ortalama ÖKD 3.19±0.28 mm (2.63-3.66), ortalama AU 22.85±0.75 mm (21.93-24.87), ultrason ile ortalama ÖKD 2.97±0.29 mm (2.46-3.35) ve ortalama AU 22.76±1.00 mm (21.68-25.50) bulundu. IOLMaster ile ortalama ÖKD 0.22 mm ve ortalama AU 0.09 mm daha yüksekti. IOLMaster ölçümleri ultrasona göre istatistiksel olarak anlamlı yüksek bulundu (p<0.0001 ve p=0.01 sırasıyla) Her iki yönteme ait ÖKD ve AU ölçümleri arasındaki korelasyon anlamlı ve çok yüksekti (r=0.922, p<0.0001 ve r=0.985, p<0.0001 sırasıyla).Sonuç: IOLMaster ve ultrason ile yapılan ölçümler yüksek korelasyon gösterse de ölçümler arasında anlamlı farklılık vardır. Biyometride optik yöntemlerin kullanılması cerrahisi sonrası olası refraktif hataları en aza indireceğinden tercih edilen yöntem olmalıdır
Purpose: To comparison of anterior chamber depth (ACD) and axial length (AL) measurements by the IOLMaster and Ascan ultrasound.Material and Method: Sixty right eyes of 60 patients (29 male and 31 female) were included in the study. Firstly, ACD and AL were measured IOLMaster (Carl Zeiss Meditec, Jena, Germany), after that A-scan ultrasound (SW-1000, Suowei Co., Tianjin, China) measurements were performed. Results were elaborated using Pearson's correlation and paired-t test.Results: the mean age of patients were 24.6±4.90 years . Mean values and ranges of ACD and AL were as follows respectively, 3.19±0.28 mm (2.63-3.66) and 22.85±0.75 mm (21.93-24.87) for IOLMaster, and 2.97±0.29 mm (2.46-3.35) and 22.76±1.00 mm (21.68-25.50) for A-scan ultrasound. Mean difference in ACD and AL measurements for IOLMaster was 0.22 mm and 0.09 mm higher than A-scan ultrasound, respectively (p<0.0001 and p=0.01, respectively). the correlation between two methods was statistically significant (r=0.922, p<0.0001 and r=0.985, p<0.0001, respectively).Conclusion: Although there was high correlation between measurements, statistically significance was found between two methods. Optic biometry should be preferred since reducing the risk of potential refractive error associated with surgery
