Abstract
The measurement of levator action is most important guide to the diagnosis, management of the blepharoptosis, especially to the choice of operation. Levator action was determined by the Berke's method on 850 normal Koreans(1700 eyes) who were seen in the Severance Hospital from November, 1985 through April, 1986. The results were as follows. 1. The average levator action of 850 normal Korean was 13.3 +/- 0.4mm, but no significant difference of levator action was found neither between right and left eye, nor between male and female. The levator action below 10 or over 60 years old was significantly weaker than the other age groups. 2. The average action of the frontalis muscle was 3.2 +/- 0.4mm, but there was no significant difference of frontalis muscle action in bilaterality or sex. The frontalis muscle action under 10 or beyond 60 years old was significantly weaker than the other age groups. 3. The average height of the palpebral fissure was 8.6 +/- 0.4mm, but the discrepancy of the height was not found neither among sex nor between both eyes. The height of the palpebral fissure becomes higher until 40 years old, whereas it becomes lower after 40 years old. 4. The correlation coefficient was 0.43.
