The lack of blood vessels at the cornea requires nutrition and protection by the diffusion of fluid from the anterior chamber and precorneal

tear film production.
tear film is an essential component of the ocular surface and can be subdivided into an anterior lipid layer, a middle aqueous layer and an innermost mucin layer.

Em corneas ulceradas, a atividade das proteinases encontra-se significativamente aumentada no filme lacrimal precorneal

The ocular surface is normally protected from microbial invasion through an intricate biochemical and anatomic relationship between the cornea, conjunctiva, lacrimal secretory apparatus and precorneal
tear film, and the eye lids.
La pelicula lacrimal precorneal
se compone de tres capas.
tear film stability was assessed by measuring the tear film break-up time by scanning the precorneal
tear film with a biomicroscope (Topcon SL1E; Topcon, Tokyo, Japan).
