COMPARISON OF ANATOMICAL EYE MEASUREMENTS IN PEDIATRIC AGE GROUPS

Abnormal changes during ocular development can affect ocular biometric parameters, which are important for diagnosis and surgical planning. The aim of this study was to determine how ocular biometric measurements of pediatric subjects in different age groups change with ocular growth. Study population consisted of 99 volunteers attending the ophthalmology outpatient clinic for routine controls. Healthy subjects aged 4-15 years with best-corrected visual acuity of 20/20 according to Snellen chart and intraocular pressure between 10-21 mmHg were included in study. Axial length, central corneal thickness, humor aquosus depth, anterior camera depth, lens thickness, limbus diameter, corpus vitreum length were measured. Independent-t test was used to compare two different groups and ANOVA method was used to compare more than two groups. As a result of study, no significant difference was found between right and left eye biometry. Humor aquosus depth, anterior camera depth, lens thickness and axial length differed significantly different between age groups. Axial length, humor aquosus depth, anterior camera depth, anterior camera depth, lens thickness and corpus vitreum length were found to significantly different between the age groups of boys. There were significant differences in humor aquosus depth and anterior camera depth parameters between age groups of girls. In this study, we investigated how biometric measurements of the eye change with age in pediatric Turkish population. It was found that anterior camera depth and humour aquosus depth increased with age, while lens thickness decreased in subjects. However, axial length and corpus vitreum length increased with increasing age in boys.
