*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.

Pinguecula? Starting point for a pterygium?
Since the conjunctival component of a pterygium is identical to a pinguecula, it has been claimed by some pathologists that the pterygium originates from a pinguecula.
