9A02.4 Meibomian gland dysfunction

International Classification of Diseases for Mortality and Morbidity Statistics, 11th Revision, v2024-01

This refers to the dysfunction of a special kind of sebaceous gland at the rim of the eyelids inside the tarsal plate, responsible for the supply of meibum, an oily substance that prevents evaporation of the eye's tear film. Meibum prevents tear spillage onto the cheek, trapping tears between the oiled edge and the eyeball, and makes the closed lids airtight.
