Meibomian glands secrete lipid into the tear film, thereby forming a thin oily layer on the tear film to prevent excessive evaporation of the tear film.1 Obstructive meibomian gland dysfunction (MGD) is characterized by changes in the viscosity of the expressed lipid.2 Eyelid temperature significantly influences not only the secretion but also the delivery of the meibum.3 Thermography is a noninvasive method for measuring the surface temperature of an object, first applied to the eye by Mapstone.4 The purposes of our study were to compare the surface temperature of the cornea and tarsal conjunctiva in patients with obstructive MGD and healthy control subjects and to examine the correlation between the surface temperature and ocular surface parameters.
