Prevalence, burden, and pharmacoeconomics of dry eye disease

Abstract

Data from a large US managed care database suggest that the prevalence of clinically diagnosed dry eye disease (DED) is 0.4% to 0.5% overall, and is highest among women and the elderly. The burden of DED to the patient can be substantial, impacting visual function, daily activities, social and physical functioning, workplace productivity, and quality of life (QOL). Preliminary analysis suggests that DED also has a considerable economic impact in terms of both direct and indirect costs. A number of therapies have been shown to improve DED signs and symptoms, but few clinical trials have addressed QOL and economic issues. Limited data suggest that topical cyclosporine has the potential to reduce physician visits and use of other medications, including artificial tears; however, further research is needed to clarify its impact on both the direct and indirect costs of DED.
