*Dr. Caccamise has very generously shared his images of patients taken while operating during the "eye season" in rural India as well as those from his private practice during the 1960's and 1970's. Many of his images are significant for their historical perspective and for techniques and conditions seen in settings in undeveloped areas.

Acute angular meibomitis (meibomianitis) with marked chemosis, lid edema, and pain OS

acute angular meibomitis ( meibomianitis ) with marked chemosis, lid edema, and pain OS

Acute meibomitis causes increasing subjective and objective symptoms as the outer canthus is approached by the involved meibomian gland. The reason for this is that there is a confluence of nerves and bloodvessls at the outer angle. In addition, the tissues are more taut and less giving. A pressure is built up in the area with resultant pressure on the nerves and pressure on the bloodvessels. The former pressure gives pain, the latter gives edema of the more easily distended bulbar conjunctiva and skin of the lids. At times there may be collateral edema of the lids of the other eye.
