Objective : To identify the variations of the double eyelid shapes and the tarsal shapes in Asians and find the association
between them.
Material and Method: Healthy subjects with natural double eyelid and age between 20-40 years were enrolled. Characteristics
and variations of the eyelid shapes and the tarsal shapes were evaluated.
Results : Of 101 subjects, 50 were males and 51 were females. The most common shape of double eyelid fold was nasally-
tapered with merging into medial upper lid fold (39.6%). Then lateral flare configuration (27.7%), parallel (26.7%), and
nasally-tapered without merging into medial skin fold (5.9%), followed in descending order of frequency. Sickle type was the
most common tarsal shapes observed (45.5%), then trapezoid (32.7%) and triangular type (21.8%). There was a significant
association between the double eyelid shapes and the tarsal shapes.
Conclusion : Variations of double eyelids and tarsus morphology were present among Asians. Ethnic differences should be
accounted for when performing aesthetic blepharoplasty as to maintain a natural ethnic appearance.
