PURPOSE: Chronic topical treatment for glaucoma may lead to Ocular Surface Disease (OSD). This study aimed to evaluate: (1) the prevalence of OSD in glaucoma patients under topical treatment, quantifying symptoms and objective ocular surface parameters and (2) the impact of ocular surface treatment on OSD and IOP control. METHODS: Patients with primary open angle or primary angle closure glaucoma under topical treatment for at least 6 months were enrolled in the study. Patients underwent symptom screening with the ocular surface disease index (OSDI) questionnaire, assessment of objective ocular surface parameters, ocular surface staining and Schirmer test. A treatment for OSD with eyelid hygiene, fluorometholone acetate 0.1%, preservative-free lubricants, free-acid supplementation and oral tetracyclin derivate was started, and the same evaluation was performed. RESULTS: In our sample (n=19), 73.68% of the patients reported severe symptoms of dry eye disease, with OSDI scores higher than 33 at baseline. Tear film instability was found in 50% of patients, while 23.53% had severe meibomian gland abnormalities. Fluorescein and lissamine green stainings were abnormal in 88.24% and 82.35% of patients, respectively. After ocular surface treatment, statistically significant improvement was found in best-corrected visual acuity (p=0.0003), OSDI score (p<0.0001), bulbar redness (p=0.0196) and fluorescein staining (p<0.0001.) Mean IOP following OSD treatment reduced -1.59 mmHg from baseline in the left eye (p=0.0510). CONCLUSION: The prevalence of OSD signs and symptoms was high in glaucoma patients under medical treatment. Short-term OSD treatment may improve ocular surface disease and IOP control, with no need to discontinue glaucoma medications.
