palpebral ,

The palpebral bones over the eyes may have provided additional protection for the eyes.

Eye: The most obvious change is darkening around the palpebral fissure.

The opening between the two lids forms the palpebral fissue.

Palpebral form- Usually upper tarsal conjunctiva of both the eyes is involved.

Palatal weakness and palpebral ptosis also have been reported in few patients.

It is usually present in the palpebral fissure.

The palpebral lobes are short but prominently raised, and the librigenae tiny.

A palpebral bone seems to be absent, meaning the eyes were not overshadowed by an upper rim as with most related species.

Small palpebral fissures - Eye width decreases with increased prenatal alcohol exposure.

Palpebral fissure is the anatomic name for the separation between the upper and lower eyelids.

The lateral palpebral arteries are small arteries which supply the eyelid.

Both the vertical and horizontal palpebral fissures (eyelid opening) are shortened.

Medical history questions documenting palpebral slant may include:

Downward-slanting Palpebral fissures (openings between the upper and lower eyelids)

Eyes and eye ridges (palpebral lobes) are absent.

Palpebral scales and superciliaries not separated by groove.

A secondary palpebral bone was lacking.

Thick palpebral bones overly the eyes.

Widening of the palpebral fissure on attempted abduction.

Eyes are upslanting and show palpebral fissures, hypertelorism, and strabismus.

The eye lobe (or palpebral lobe) is poorly defined.

This results in the relaxation of the tarsal fold allowing tissue to slack over the palpebral fissure.

These widen the palpebral aperture.

Downward slanting palpebral fissures (separation between upper and lower eye lids)

Affected individuals are dysmorphic with macrodolichocephaly, downslanting palpebral fissures and a pointed chin.
