Document Summary
The rest is enclosed and protected by a fat cushion and walls of the orbit. Shade eyes from sunlight and prevent perspiration trickling down the forehead from reaching the eyes. Eyelids are separated by the palpebral fissure and meet at the medial and lateral commissures. The lacrimal caruncle contains oily secretion that can collect at the medial commissure (in most asians a epicanthic fold commonly appears on both sides) Tarsal glands are embedded in the tarsal plates and their ducts open at the eyelid edge just posterior to the eyelashes. Transparent mucous membrane that lines the eyelids as the palpebral conjunctiva and folds back over the anterior surface as the bulbar conjunctiva. The conjunctiva sac is where the lens lies and where you get eye drops. Consists of the lacrimal gland and the ducts that drain lacrimal secretions into the nasal cavity.
