Fatty Acids (EFA) have been shown to diminish inflammatory responses in many human inflammatory diseases, and interest in the use of omega-3 and omega-6 fatty acids for disease treatment has resulted in several small studies as well as the use (and over-the-counter availability) of EFA-containing nutritional supplements, including several specifically for the treatment of DED. Unfortunately, the effects of Omega 3 on dry eye disease have not been established to date. The purpose of this study is to better understand the role of Omega 3 plays in the regulating tear osmolarity in patients with established findings consistent with dry eye disease.
