Glaucoma is a common disease with an increasing prevalence [1]. Ocular surface disease (OSD) is also common, and its prevalence is increasing [2,3], due in part to the adverse effects of topical glaucoma medications [4,5]. Given this glaucoma/OSD association, David A. Sullivan, MS, PhD (Boston, MA, USA) and Amy Gallant Sullivan (Paris, France) on behalf of the Tear Film & Ocular Surface Society (TFOS), and in collaboration with Miriam Kolko, MD, PhD (Copenhagen University Hospital & University of Copenhagen, Denmark), organized a one-day meeting which was held on Saturday, October 22, in Cernobbio, Italy. This meeting focused on the impact of glaucoma medications on the ocular surface, and how OSD can influence glaucoma treatment. The term "ocular surface" encompasses the surface (cornea and conjunctiva), tear film, and adnexa (lacrimal and meibomian glands). The speakers included internationally renowned glaucoma and OSD experts. The evidence-based proceedings of this meeting are presented in this TFOS Experts' Meeting report.
