Iyer JV, et al. – The goal of this paper was to investigate the incidence of topical lubricant use as a surrogate marker for underlying ocular surface disease (OSD), in medically and surgically treated glaucoma patients. The medical and surgical management of glaucoma displayed an adverse effect on the ocular surface. Chronic use of glaucoma medications correlated with a high incidence of ocular lubricant use. A link was found between mitomycin C (MMC)–augmented trabeculectomy with an even higher incidence of ocular lubricant use.
