It is a system of glycoproteins and lipid-linked carbohydrates that forms along the ocular surface epithelium apical membrane and is prominent at the edges of the microplicae. It is adjacent to the innermost layer of the tear fluid, the mucous layer. The biochemical nature of the glycoproteins is suspected of playing a vital role in sustaining the tear film on the ocular surface epithelium.
