meibomian gland
Quick Summary
The meibomian glands, also known as tarsal glands, are a type of sebaceous gland located along the eyelid margins. Their primary function is to secrete an oily substance that forms the outer lipid layer of the tear film. This lipid layer is crucial for preventing the evaporation of tears, which helps to keep the eye surface moist and healthy. Tears themselves are produced by lacrimal glands and are essential for preventing dry eye, providing nutrition and oxygen to the eye, and possessing antibacterial properties. The meibomian glands are easily visible on the eyelid margins when the eyelids are everted.123
