Purpose. To identify risk factors for developing ocular surface disease (OSD), to verify the prevalence of OSD, and to record efficacy of questionnaires in identifying symptoms' impact on patients' quality of life. Methods. This was an observational, cross-sectional study of patients with topically treated glaucoma. Tear film break-up time (TFBUT) and punctate keratitis were evaluated; 2 quality-of-life questionnaires (National Eye Institute-Visual Function Questionnaire 25 and Glaucoma Symptom Scale) were submitted to all patients. Class of previous and current intraocular pressure (IOP)-lowering drugs, number of drugs, number of drops/day, and total and current benzalkonium chloride (BAK) exposure were collected. results. A total of 233 patients completed the study. TFBUT was abnormal in 71 (30.5%) eyes; punctate keratitis was present in 74 (31.7%). Keratitis was more frequent with increasing number of eye-drops (p=0.008) and number of instillations per day (p=0.009). Ocular surface disease was present in 97 (41.6%) patients and was statistically related to number of medications used (p=0.026). The univariate analysis pointed out that patients with OSD were older (p=0.04), had lower IOP values (p=0.03), were topically treated for more time (p
