• Sixty consecutive patients with active ocular rosacea underwent Schirmer's test without anesthesia. A randomly selected group of 120 patients without rosacea, matched for age and sex, served as controls. The prevalence of dry eyes was significantly greater in the patients with rosacea. The coexistence of keratoconjunctivitis sicca and ocular rosacea probably causes a high level of symptoms that lead patients to examination and recognition.
