The eyelids are composed of the following structures taken in their order from without inward: integument, areolar tissue, fibers of the Orbicularis oculi, tarsus, orbital septum, tarsal glands and conjunctiva. The upper eyelid has, in addition, the aponeurosis of the Levator palpebræ superioris (Fig. 893).

The integument is extremely thin, and continuous at the margins of the eyelids with the conjunctiva.

The subcutaneous areolar tissue is very lax and delicate, and seldom contains any fat.

The palpebral fibers of the Orbicularis oculi are thin, pale in color, and possess an involuntary action.
