What causes aqueous tear deficiency?
Aqueous deficient dry eye is characterized by an inadequate wet layer of the tear film that is produced by the lacrimal gland. The risk of aqueous deficiency increases with age. Obstructions in the lacrimal glands or ducts, or other diseases of the lacrimal glands can cause aqueous deficiency.
What is tear film deficiency?
Lipid tear deficiency is most commonly caused by blepharitis or meibomian (oil producing) gland dysfunction. This leads to abnormally increased evaporation of the tears from the surface of the eye. Mucin deficiency can be caused by conditions such as vitamin A deficiency, chemical injury, and Stevens-Johnson syndrome.
What produces the tear film?
The tear film is a complex mixture of substances secreted from multiple sources on the ocular surface, including the lacrimal gland, the accessory lacrimal glands, the meibomian glands, and the goblet cells.
