Blepharitis of the eyelid margins. Posterior blepharitis and Meibomian gland dysfunction are frequently associated with rosacea and can be seen during an ocular examination of the posterior eyelid margin. The Meibomian glands may appear caked with oil or visibly obstructed. Cultures of the eyelid margins can be a clear indicator for patients suffering from recurrent anterior blepharitis with severe inflammation, in addition to patients who are not responding to therapy. Measurements of tear osmolarity may be beneficial in diagnosing concurrent dry eye syndrome (DES), which may be responsible for overlapping symptoms and would allow the physician to decipher between conditions and
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. Submucosal glands Submucosal glands can refer to various racemose exocrine glands of the mucous type. These glands secrete mucus to facilitate the movement
