Katarakt Hastalarında Ultrasonik Biyomikroskopla Ölçülen Siliyer Sulkus Çapı ile IOL Masterla Ölçülebilen Parametreler Arasındaki İlişki

Pur po se: To determine the mean sulcus diameters in patients older than 50 years with senile cataract and to analyze the correlations of\udsulcus diameters with IOLMaster measurements of corneal diameter (white to white), axial length, keratometry and anterior chamber depth.\udMethods: 31 eyes of 20 consecutive patients who were scheduled for cataract operation were included in the study. The same person performed\udroutine ophthalmological examination, ultrasound biomicroscopy (UBM) and IOLMaster measurements. Keratometry, corneal\uddiameter, anterior chamber depth and axial length were measured with IOLMaster. Horizontal and vertical sulcus diameters were measured\udfrom iris pigment epithelium to iris pigment epithelium on the best UBM images in terms of centralization.\udResults: Mean patient age was 71.03±8.6 (min: 51, maks: 89) years. Mean vertical sulcus diameter was 13.59±0.73, mean horizontal sulcus\uddiameter was 13.36±0.72 mm, and the mean of horizontal and vertical sulcus diameters was 13.47±0.71 mm. Mean corneal diameter\udwas 11.67±0.46 mm, mean keratometry was 43.86±1.46 D, mean axial length was 23.2±0.93 mm, and mean anterior chamber depth was\ud3.02±0.35 mm. There were statistically significant correlations between horizontal corneal diameter and horizontal sulcus diameter (r: 0.37;\udp<0.05), horizontal corneal diameter and mean sulcus diameter (r: 0.36; p<0.05), axial length and horizontal sulcus diameter (r: 0.56;\udp<0.05), axial length and vertical sulcus diameter (r: 0.56; p<0.05), and axial length and mean sulcus diameter (r: 0.57; p<0.05). The correlations\udbetween other parameters were not statistically significant.\udConclusion: The sulcus diameters measured in our study were higher when compared to other studies in the literature. Only corneal\uddiameter and axial length were correlated with sulcus diameters. The strongest association in our study was between axial length and sulcus\uddiameters.
