Keratoconjunctivitis sicca and corneal ulcers

We reviewed the records of 56 patients (109 eyes) who satisfied our criteria for keratoconjunctivitis sicca (KCS) to determine factors associated with the development of sterile corneal ulcers. The patient's age, sex, and associated local ocular surface and/or systemic disease were studied. We found a statistically significant association between the development of corneal ulceration and the presence of an underlying condition or disease state, especially chronic rheumatoid arthritis. Patient sex and age were not significantly associated with the development of corneal ulceration. We present three case histories that illustrate the complications that arise in managing KCS plus an associated disease and methods of management.
