COMPARISON OF ANTERIOR SEGMENT PARAMETERS IN PREADOLESCENT CHILDREN AND MIDDLE AGED ADULTS

Abstract

Objective: Comparison of anterior segment parameters, anterior/posterior keratometry, and corneal astigmatism values ​​in preadolescent children and middle-aged adults. Material and Methods: Right eye measurements from a total of 100 subjects (50 children and 50 adults) were included in the study. Central corneal thickness (CCT), aqueous depth (AD), anterior camera volume (ACV), iridocorneal angle (ICA), anterior/posterior keratometry (ant.K/post.K) values, ​​and corneal astigmatism (Cast.) values ​​were recorded. The groups were compared between themselves, and they were compared in terms of sex within each group. Results: The mean age of the children was 7.82±1.45 and the mean age of the adults was 53.84±6.81. There were significant differences between the groups in terms of age and CCT, AD, ACV, ICA, anterior corneal astigmatism (ant.Cast.), and posterior vertical K (post.K2) values. There were significant differences in AD and ICA between males and females among the children (p=0.036, p=0.005, respectively). There were also significant differences in ACV and ICA between males and females among the adults (p=0.012, p=0.006, respectively). In the correlation analysis, CCT, AD, ACV, ICA, and post.K2 were negatively correlated with age, while ant.Cast. was positively correlated. Conclusion: In our study, CCT and anterior segment parameters were significantly lower in adults. This situation was more evident in women. It is useful to consider these differences in the diagnosis and follow-up of corneal diseases, in deciding on refractive surgery, and in determining the type of surgery, as well as in the diagnosis and follow-up of glaucoma.
