PURPOSE/METHODS: The cause of Mooren's ulcer is unknown. We examined a
patient with chronic hepatitis C who had a corneal ulceration that re
sembled Mooren's corneal ulcer. RESULTS/CONCLUSION: The corneal ulcera
tion progressed despite appropriate medical and surgical interventions
. Recombinant interferon alpha 2b finally led to resolution of the pro
cess. The resolution correlated with normalization of the patient's li
ver function tests. Corneal ulcerations that resemble Mooren's ulcer m
ay be associated with hepatitis C. Recombinant interferon alpha 2b see
ms to induce remission in the corneal as well as the systemic conditio
n.
