*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.
Phlyctenular keratoconjunctivitis (PKC) is a classic limbally located phlyctenule. It occurs primarily in children. It is considered to be an allergic reaction to toxins. In India, the first consideration was an allergic response to tuberculosis until proved otherwise. An older term for phlyctenular keratoconjunctivitis (PKC) was keratoconjunctivitis scrophulosa or eccematosa.
Formerly related to tuberculosis, PKC was also called keratoconjunctivitis scrofulosa. It is now considered to be an allergic response to other antigens.
Considered to be an allergic reaction to toxins or allergens of conjunctival infections. At times it appears to be an immune reaction to toxins or allergens within the patient's body. A phylectenular reaction appears early as a whitish elevation within a hyperemic limbus.
