*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.

Pseudopterygium
Pseudopterygium is sometimes referred to as cicatricial pterygium. A true pterygium has edges that can be elevated with forceps or under which a probe can be passed A true pterygium aries from a pinguecula. A pseudopterygium arises from destruction of the marginal, corneal epithelium through trauma, e.g. caustics, burns or inflammation.The adjacent conjunctiva migrates to the injured area and becomes fixed to it. A pseudopterygium does not show any tendency to progress. It is able to develop at any point of the corneal circumference.
