Abstract

Background and Objectives: Ocular torsion may be a result of vestibulopathy. The funduscopy is the most reliable method of measuring an ocular torsion. However, the reference value of ocular torsion in Korean is available at only limited ages. Therefore, we analyzed the angle of ocular torsion more age-specific than previous study. Materials and Methods: We used the fundus photograph of health check-up visitor. And age and sex specific average angle of ocular torsion was measured. Results: The right and left average angle of ocular torsion were 7.7±3.6°, 5.3±3.0°, respectively. In addition, there was no significant difference in age or sex specific angle of ocular torsion. Conclusion: This result might give an aid to evaluating the function of otolithic organ by measurement of ocular torsion.
