Abstract
Purpose
To evaluate anterior chamber biometry of the eyes of normal children using ultrasound biomicroscopy (UBM) and to evaluate the differences in biometry between children and adults, and before and after pupil dilation in children.
Methods
Anterior chamber depth (ACD) and trabeculariris angle (TIA) were measured in 94 normal children and 15 normal adults using UBM. Before and after pupil dilation were measured in 42 children with emmetropic and hyperopic eyes.
Results
In 66 emmetropic children, ACD and TIA were 2.93±0.18 mm and 34.42±4.02°, respectively. In 28 hyperopic children, ACD and TIA were 2.92±0.21 mm and 35.05±4.42°, respectively. There was no significant difference in anterior chamber biometry associated with the refraction. ACD did not differ between children and adults, but TIA in children was wider than in adults. There was no significant difference in ACD or TIA before versus after pupil dilation in any case.
Conclusions
Anterior chamber biometry in children showed no differences before and after pupil dilation. Also, there was no difference in ACD of children as compared to adults; however, TIA in children was significantly wider than in adults.
