PURPOSE: To determine the presence of symmetry of anterior segment morphometric measurements between normal adelphic eyes. METHODS: One hundred and seventy-eight eyes of 89 subjects with normal ophthalmic examination were examined by ultrasound biomicroscopy (UBM). In each eye, the anterior chamber depth (ACD) as well as 11 other measurements that characterize anterior segment morphometry were measured in 4 different quadrants (superior, nasal, inferior and temporal). The presence of symmetry between right and left eye for each of these variables was then compared for each meridian. RESULTS: No significant statistical differences were observed concerning anterior segment morphometry between right and left eyes for most measured parameters. Only two variables, in two different meridians, presented statistical significant differences between right and left eyes. The difference, however, was inferior to 0.025 mm, which is beyond the precision of UBM and therefore was not considered to be clinically significant. Pearson correlation analysis demonstrated the presence of a statistical significant correlation, with a moderate intensity for the majority of the variables except ACD, whose correlation was excellent. CONCLUSION: This study demonstrated that symmetry of morphometric measurements between right and left eyes is expected to occur, provided these eyes have similar refractive errors and biometric measurements.
