*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.

Trachoma: limbal arcade vs pannus
The gray area at the superior limbus is an essential zone in deciding whether vessels in that area meet the requirement for being called part of a pannus. If the vessels are seen to loop back without entering the cornea beyond the gray zone, they are part of the normal limbal arcade and not part of a pannus. A pannus is young vascularized connective tissue (granulation tissue) growing into the cornea beyond the gray zone with its normal limbal arcade. There is also an aberrant lash in the upper lid that is part of the trachoma afflicting this eye.
pannus crassus: a florid form of pannus in certain trachoma patients.
