Comparison of anterior segment parameters with pentacam according to age in emmetropic eyes
Journal Title: Dicle Tıp Dergisi - Year 2013, Vol 40, Issue 4
Abstract
Objective: It was aimed to compare anterior segment parameters obtained by rotating Scheimpflug camera system according to age groups. Methods: 290 eyes of 145 emmetropic subjects were included in the study. Subjects were divided in three age groups. Group 1 comprised the subjects age up to 20 years, Group 2 comprised the subjects age between 21 and 40 and Group 3 comprised the subjects between 41 years and older. In all subjects, flat keratometry (K1), steep keratometry (K2), mean corneal power (Km), maximum keratometry (Kmax), central corneal thickness (CCT), apex corneal thickness (ACT), thinnest corneal thickness (TCT), anterior chamber volume (ACV) and anterior chamber depth (ACD) were obtained by using rotating Scheimpflug camera system. To eliminate operator dependent variables, automatic release mode was used. All measurements were obtained by the same examiner. Results: The study included 72 female and 73 male subjects. The mean age of the subjects was 31.37±12.29 years (range, 8-65). There were no significant differences in keratometric values between age groups. There was significant difference between Groups 1 and 3 and Groups 2 and 3 in the mean CCT, ACT and TCT (p<0.05). There was significant difference between the groups in the mean ACD and ACV. There significant positive correlation between age and CCT (r=0.181, p=0.001), ACT (r=0.161, p=0.006) and TCT (r=0.16, p=0.006). There were significant negative correlations between age and ACD (r=-0.376, p<0.001) and ACV (r=-0.367, p<0.001). Conclusion: In the emmetropic eyes, significant reduction was found in ACD and ACV, while there was significant increase in CCT, ACT and TCT by age. Key words: Corneal topography, anterior segment, emetropic eyes, pentacam
