Abstract

Purpose: To determine the prevalence of signs and symptoms of ocular surface disease (OSD) in patients using topical intraocular pressure-lowering therapy.<br />Methods: In this cross-sectional study, 40 patients were consecutively recruited from the glaucoma clinic of a public hospital located in Rio de Janeiro, Brazil. Eligible patients were 18 years of age or older, with primary open-angle glaucoma or ocular hypertension and on the same topical ocular therapy for at least 6 months. The following data were considered: sex, age, medication history and number of years on topical intraocular pressure-lowering therapy. All patients underwent an evaluation of the ocular surface which included: an interview using the Ocular Surface Disease Index® (OSDI®) questionnaire, break-up time, biomicroscopy, fluorescein corneal staining and rose Bengal ocular surface staining.<br />Results: The mean OSDI® score was 24.6 ± 20.7. Most patients (67.5%) had an abnormal score on the OSDI® questionnaire. In 25% of patients, the score was consistent with mild symptoms, 12.5% with moderate symptoms and 30% with severe symptoms. Blepharitis and punctate keratitis were diagnosed in 42.5% and 20% of patients respectively. Tear film instability was observed in 75% of patients and ocular surface staining with rose Bengal in 35%. A positive statistically significant correlation (r=0.4; p=0.01) was found between OSDI® scores and the duration of topical intraocular pressure-lowering therapy.<br />Conclusion: Patients with primary open-angle glaucoma or ocular hypertension on topical intraocular pressure-lowering therapy have high prevalence of OSD. Longer duration since diagnosis is significantly correlated with worsening of OSD symptoms.
