Abstract
The palpebral fissure height of 67 healthy koreans were examined. Measurements were obtained with high resolution digital image processing, with the eyes in primary gaze, in 45-degree right gaze, and in 45-degree left gaze. When a criterion of equal to or greater than 1mm was used, the prevalence of physiologic palpebral fissure asymmetry was 13.1 (8/61) in primary gaze, 24.6%(15/61) in right gaze, and 16.4%(10/61) in left gaze. The largest observed palpebral fissure asymmetry was 1.795mm. After correcting for any existing fissure asymmetry in primary gaze, two-tailed trivariate analysis of variance showed that most corrected palpebral fissure asymmetries are less than 1mm and adducting eye tended to be wider in horizontal gaze. Also this effect of wider fissure in the adducting eye was the same for right gaze or left gaze, and found no significant effect of gender on palpebral fissure asymmetry. The mean increase in the palpebral fissure of the adducting eye was 0.29mm for right gaze and 0.21mm for left gaze.
