Most affected people also experience eye problems, varying from colobomata of the lower eyelids and aplasia of lid lashes to short, down-slanting palpebral fissures, and missing eyelashes.

The distinct facial feature include upslanting palpebral fissures, a broad nose with rounded tip, long philtrum with a thin upper lip, pointed chin and prominent ears ( Vasudevan 2005)
33.
Palpebral fissure length ( PFL ) is measured in millimeters with either calipers or a clear ruler and then compared to a PFL growth chart, also developed by the University of Washington.

The lacrimal part ( tensor tarsi ) is a small, thin muscle, about 6 mm in breadth and 12 mm in length, situated behind the medial palpebral ligament and lacrimal sac.
35.
The smaller " palpebral portion " lies close to the eye, along the inner surface of the eyelid; if the upper eyelid is everted, the palpebral portion can be seen.

37.
The orbital portion is thicker and of a reddish color; its fibers form a complete ellipse without interruption at the lateral palpebral commissure; the upper fibers of this portion blend with the Corrugator.
38.
The orbital portion contains fine interlobular ducts that unite to form 3 5 main excretory ducts, joining 5 7 ducts in the palpebral portion before the secreted fluid may enter on the surface of the eye.
39.
Its " lateral surface " is smooth, continuous with the anterior surface of the body, and gives attachment to the Quadratus labii superioris, the Orbicularis oculi, and the medial palpebral ligament.

The " superior palpebral " arch anastomoses, at the lateral angle of the orbit, with the zygomatico�rbital branch of the temporal artery and with the upper of the two lateral palpebral branches from the lacrimal artery.
