Along the inner margin of the tarsus are modified sebaceous glands known as tarsal glands (or meibomian glands), aligned vertically within the tarsi: 30 to 40 glands in the upper lid, and 20 to 30 in the lower lid, which secrete a lipid-rich product which helps keep the lacrimal secretions or tears from evaporating too quickly, thus keeping the ...
Meibomian glands (also called tarsal glands, palpebral glands, and tarsoconjunctival glands) are sebaceous glands along the rims of the eyelid inside the tarsal plate. They produce meibum , an oily substance that prevents evaporation of the eye's tear film .
The lacrimal punctum (pl.: puncta) or lacrimal point is a minute opening on the summits of the lacrimal papillae, seen on the margins of the eyelids at the lateral extremity of the lacrimal lake.

Ciaccio's glands or Wolfring's glands are small tubular accessory lacrimal glands (glandulae lacrimales accessoriae) found in the lacrimal caruncle of the eyelid. These accessory lacrimal glands are located in the upper border of the tarsus , approximately in the middle between the extremities of the tarsal glands . [ 1 ]
