Abstract

Abstract Dry eye disease (DED) is common, multifactorial disease in which vicious cycle of inflammation on ocular surface plays a major role. Thus, therapeutic approaches focused on the modulation of ocular surface inflammation have been introduced, and topical and systemic anti-inflammatory drugs including corticosteroids, cyclosporine A, and doxycycline have been shown to be effective in treatment of DED. Recent studies suggest that supplementation of omega-3 (ω3) and omega-6 (ω6) essential fatty acids may be helpful for modulation of ocular surface inflammation, and systemic and topical application of the essential fatty acids can be an alternative strategy for the treatment of DED. In this chapter, the results of the experimental studies and clinical trial to evaluate the efficacy of systemic and topical ω3 and ω6 essential fatty acids supplementation for the treatment of DED will be summarized. Therapeutic guideline, possible side effects, and future perspective of the supplementation of the essential fatty acid will also be discussed.
