![]() ![]() Lastly, the mucinous layer, which is supplied by both the conjunctiva and the cornea (conjunctival goblet and epithelial cells and corneal epithelial cells) stabilizes the aqueous layer (by providing a viscous medium), maintains attachment of the tear film to the corneal epithelium through the use of glycoproteins, and helps uniformly distribute the tear film layer through the creation of a low surface tension environment. This layer has many functions including but not limited to corneal antimicrobial defense, lubrication, nutrition and supply of oxygen, mechanical clearance of debris, and regulation of cellular functions. The proteins in this layer include lysozyme, lactoferrin, transferrin, ceruloplasmin, metalloproteinases, defensins, and immunoglobulins. The aqueous layer comprises the middle layer of the tear film and contains proteins, cytokines, growth factors, electrolytes, oxygen, and glucose and is supplied by the main and accessory lacrimal glands. This layer is responsible for lubrication and ensuring uniform spread of the tear film, prevention of evaporation, and stabilization of a smooth ocular surface for refraction. The outermost layer consists of lipids that are secreted by the meibomian glands. The tear film consists of three layers (although a contemporary model proposes a gradient model rather than distinctly layered model).

Paralysis of the seventh cranial nerve can be caused by Bell’s palsy, tumors, or trauma. ![]() Paralytic lagophthalmos results from a paralyzed cranial nerve, thus preventing the eyelids from complete closure. The fatty tissue can deteriorate for several reasons, including the presence of an autoimmune disease. Less cushioning causes the eye to sink further into the socket, making it more difficult for the lids to completely close. One common cause of this type of lagophthalmos is a decrease in fatty tissue behind the eyeball. Nocturnal lagophthalmos occurs during sleep, so people with this condition may be unaware they have it. ![]() Colliding eyelashes or tasks that require a high level of focus (such as working on a computer) can contribute to blink lagophthalmos. An incomplete blink can lead to dry spots on the eye and other uncomfortable dry eye symptoms. When the eyelids don’t fully close during a blink, this is called “blink lagophthalmos.” Blinking keeps the eyes lubricated by spreading the tear film evenly along the eyes’ surface.
