Normal range of eye movement and its relationship to age

Purpose To determine the range of eye movement in normal human subjects and to investigate the effect of age on eye movement. Methods We enrolled 261 healthy subjects, 5–91 years of age for this prospective observational study. Photographs were obtained in the cardinal gaze positions and processed u...

Description
Summary:Purpose To determine the range of eye movement in normal human subjects and to investigate the effect of age on eye movement. Methods We enrolled 261 healthy subjects, 5–91 years of age for this prospective observational study. Photographs were obtained in the cardinal gaze positions and processed using Photoshop. The processed images were analyzed using the Image J program to measure the angle of eye movement. The angle of eye movement was quantified using a modified limbus test. We measured the angle of eye movement in adduction, abduction, elevation, and depression. Results The normal ranges of eye movement were 44.9 ± 7.2° in adduction, 44.2 ± 6.8° in adduction, 27.9 ± 7.6° in elevation, and 47.1 ± 8.0° in depression. There were significant negative correlations between the angles of horizontal and upward gazes and age (R = −0.294 in adduction, R = −0.355 in abduction, and R = −0.506 in elevation, all p
