Another type of accessory lacrimal gland are "Krause's glands", which are smaller, more numerous than "Ciaccio's glands" and are found along the superior and inferior fornices of the conjunctival sac. Ciaccio's glands Ciaccio's glands or Wolfring's glands are small tubular accessory lacrimal glands ("glandulae lacrimales accessoriae") found in the lacrimal caruncle of the eyelid. They are located in the upper border of the tarsus, approximately in the middle between the extremities of the tarsal glands. Sometimes they are
Submucosal glands sacs (acini) where the mucus originates. Each sac (acinus) has one end that can open and close (dilate) to allow the mucus out. The acini empty into little tubes (tubules) that lead to a reservoir (collecting duct) that has a portal through the "skin" (mucosa) that can open and close allowing the mucus into the main tube. The submucosal glands are a companion to goblet cells which also produce mucus, and are found lining the same tubes.
