Morphologic Study of Upper Eyelid Contour and Functional Evaluation of Levator Palpebrae Superioris Muscle in Adult and Young People

ABSTRACT

PURPOSE & METHOD: The authors analyzed the morphology of upper eyelid of 480 normal eyes of medical college students, nurses, and officers in our hospital. RESULT: The height of eyelid fissure was 8.33 mm in right eye, 8.43 mm in left eye in men and 9.05 mm in right eye, 9.14 mm in left eye in women. Intercanthal distance was 36.96 mm in men and 36.52 mm in women. The length of palpebral fissure was 27.43 mm in right eye, 27.66 mm in left eye in men and 27.82 mm in right eye, 27.87 mm in left eye in women. The epicanthal fold was found in 15.0% of men and in 10.0% of women. Most frequent type of epicanthal fold was epicanthus tarsalis. The upper eyelid crease was found in 24.2% of total participants, and 16.7% in men and 31.7% in women. The levator function according to Berke's method was 13.46 mm in right eye, 13.43 mm in left eye in men and 13.74 mm in right eye, 13.67 mm in left eye in women. MRD1 was 2.39 mm in right eye, 2.42 mm in left eye in men and 2.70 mm in right eye, 2.65 mm in left eye in women. The MLD as similar values in the evaluation of levator function was 5.89 mm in right eye, 6.08 mm in left eye in men and 4.99 mm in right eye, 5.01 mm in left eye in women. CONCLUSION: In this study we could conclude that morphological values of eyelid and levator function were measured similarly to those in western people although values such as MRD1 was noted different. We suggest that our data were helpful to decision of the standard values of Korean adult and young people.
