Abstract

Purpose: To compare anterior chamber depth (ACD) in patients with or without cataract by using IOL-Master, Pentacam-Scheimpflug and keratometry methods. Material and Method: Patients were classified into two groups as with (Group 1) or without cataract (Group 2). All patients had under- gone complete ophthalmologic examination including measurement of visual acuity, slit-lamp examination, fundoscopy, and intraocular pressure measurement with an applanation tonometer. ACD measurements were obtained by using keratometric measurements with the Haag-Streit Javal keratometer, IOL-Master (Carl Zeiss Meditec, Germany) and Pentacam (Oculus, Germany). Theoretical ACD was calcu- lated by the (K1+K2)/2 x 0.29+0.5 formula. Both groups were evaluated among themselves via the measurement methods. Results: Group 1 included 150 eyes of 120 patients and Group 2 included 150 eyes of 80 patients. The mean age was 72.57 (62-87) and 47.7 (40-60) years respectively. In Group 1 the mean ACD value obtained was 2.15 mm (2.08-2.26 mm) by IOL-Master and 2.44 mm (2.31-2.56 mm) by Pentacam. Theoretical ACD was 2.12 mm (2.03-2.26 mm). In Group 2 the mean ACD value obtained was 3.58 mm (3.32-3.71 mm) by IOL-Master and 3.85 mm (3.73-3.99 mm) by Pentacam. Theoretical ACD was 3.55 mm (3.34-3.69 mm). According to measurement methods, ACD was significantly smaller in group 1 than group 2. There was no significant difference between measurement methods regarding ACD. Discussion: ACD decreases in inverse proportion to the development of cataracts and age. On the basis of the calculation method, IOL- Master was more reliable than Pentacam.

Özet

Amaç: Kataraktı olan ve olmayan hastaların ön kamara derinliklerinin; IOL-Master Pentacam-Scheimpflug ve keratometrik yöntemler kullanılarak karşılaştırılması. Gereç ve Yöntem: Hastalar kataraktı olan (Grup 1) ve olmayan (Grup 2) gruplar olarak sınıflandırıldı. Çalışmaya alınan tüm hastaların görme keskinliği, biomikroskopik ön ve arka segment muayenesi, aplanasyon tonometresi ile göz içi basınçları ölçümü, Haag-Streit Javal tipi keratometri ile ölçülen keratometri değerleri, IOL-Master (Carl Zeiss Meditec, Almanya) ve Pentacam (Oculus ,Almanya) kullanılarak ön kamara derinliği ölçümü değerleri kaydedildi. Teorik ön kamara derinliği (ÖKD); (K1+K2) / 2 X 0.29+0.5 formülü kullanılarak hesap- lanmıştır. Her iki grup kendi arasında ve ölçüm metotları açısından değerlendirilmiştir. Bulgular: Grup 1’de yaş ortalaması 72.57±7.31 (62-87) olan 120 hastanın 150 gözü, Grup 2’de yaş ortalaması 47.73±5.22 (40-60) olan 80 hastanın 150 gözü değerlendirilmiştir. Ortalama ön kamara derinliği Grup 1’de IOL-Master ile ortalama 2.15±0.11 mm (2.08-2.26 mm), Pentacam ile ortalama 2.44±0.14 mm (2.31-2.56 mm), teorik ön kamara derinliği ise 2.12±0.14 mm (2.03-2.26 mm) bulunmuştur. Grup 2’de ise IOL-Master ile ortalama 3.58±0.09 mm (3.32-3.71 mm), Pentacam ile ortalama 3.85±0.11 mm ( 3.73-3.99 mm) ve teorik ön kamara derinliği ise 3.55±0.11 mm ( 3.3-3.69 mm) olarak ölçülmüştür. Grup 1’de ön kamara derinliği, Grup 2’e göre ölçüm metotları ile istatistik- sel olarak anlamlı olarak azalmıştır. (p<0.05) Ölçüm metotlarının arasında; ön kamaradaki azalmanın değerlendirilmesinde istatistiksel olarak bir fark görülmemiştir. Tartışma: Ön kamara derinliği; yaşla ve katarakt gelişimi ile ters orantılı olarak azalır. Teorik ÖKD baz alındığında IOL-Master, ÖKD hesaplanmasında Pentacam’a göre daha güvenilir bir testtir.
