title: An immunopathologic study of giant papillary conjunctivitis associated with an ocular prosthesis.
abstract: A 21-year-old woman, whose left eye had been enucleated when she was 2 years old, developed giant papillary conjunctivitis and experienced ocular discomfort and increased tearing when she wore her prosthesis. Cultures grew normal flora, and topical antibiotics failed to relieve her symptoms. Immunopathologic studies of a conjunctival biopsy specimen disclosed plasma cells of all five classes of immunoglobulins in the substantia propria and many IgE-containing cells. Russell bodies found in some of the plasma cells were of the IgM and IgG types. The patient was treated with a 2% solution of cromolyn sodium, applied four times a day. Within one month, her symptoms had resolved, there was less conjunctival congestion, and the papillae were much less prominent. Our findings suggested that there may be a heterogenous humoral response in giant papillary conjunctivitis along with a strong immediate (Type I) hypersensitivity component.
