The superior tarsus (tarsus superior; superior tarsal plate), the larger, is of a semilunar form, about 10 mm (0.4 in) in breadth at the center, and gradually narrowing toward its extremities. It is adjoined by the superior tarsal muscle. To the anterior surface of this plate the aponeurosis of the levator palpebrae superioris is attached.
Meibomian glands (also called tarsal glands, palpebral glands, and tarsoconjunctival glands) are sebaceous glands along the rims of the eyelid inside the tarsal plate. They produce meibum , an oily substance that prevents evaporation of the eye's tear film .
Meibomian glands in the lower eyelid imaged under amber light to show vasculature support and the gland structure. Meibomian gland dysfunction (MGD, also meibomitis or meibomianitis) is a chronic disease of the meibomian glands, which is commonly characterized by obstruction of the end of the duct that delivers the secretion produced by the glands (called meibum) to the eye surface, which ...

A review of treatments showed that the anti-mite drug ivermectin can be an effective treatment for reducing symptoms. [24] Eye drops or ointments containing corticosteroids are frequently used in conjunction with antibiotics and can reduce eyelid inflammation. [4] [5] [25] The supplement n-acetylcysteine may be effective for blepharitis. [26]
Conjunctival concretions are generally asymptomatic.Common symptoms include eye discomfort, eye irritation, and foreign body sensation. Sometimes, the larger, harder or multiple concretions make the rubbing off of the superficial layers of the conjunctiva or eyelids to cause conjunctival abrasion, especially prominent when blinking.
The eyebrows, eyelids, eyelashes, lacrimal gland and drainage apparatus all play a crucial role with regards to globe protection, lubrication, and minimizing the risk of ocular infection. [1] The adnexal structures also help to keep the cornea moist and clean. One source defines "ocular adnexa" as the orbit, conjunctiva, and eyelids. [2]
The superior tarsal muscle receives its innervation from the sympathetic nervous system.Postganglionic sympathetic fibers originate in the superior cervical ganglion, and travel via the internal carotid plexus, where small branches communicate with the oculomotor nerve as it passes through the cavernous sinus.
