The skin crease is
formed by the dermal attachments of the levator aponeurosis which is usually
8 to 10 mm above the lash line in the female Caucasians. The lid fold is
seen above the upper skin crease as a projecting bulge. The fold represents
the anterior projection of the preaponeurotic fat pad. The amount of projection
is dependent on :
-
the amount of preaponeurotic
fat present
-
the state of attachment
of preaponeurotic fat
-
the level of fusion
of orbital septum to the levator aponeurosis.
The fusion between the orbital septum and the levator aponeurosis
is around 3 to 5 mm superior to the tarsal plate in the Caucasian.
A high skin creases gives the impression of a larger eye
opening and accentuates the expression of the upper lid. This is much favored
by actresses. A low skin crease, in contrast, gives the eye a narrow and
rather expressionless look. However, this can give mystery and intrigue
to some actresses.
