Methods for reducing angiogenesis, inflammation, and vascular permeability in a subject by administering an epoxymetabolite of Docosahexaenoic acid (DHA) and Eicosapentaenoic acid (EPA), e.g., as listed in Table A, e.g., one or both of 17,18-epoxyeicosatetraenoic acid (EEQ) and 19,20-epoxydocosapentaenoic acid (EDP), e.g., for the treatment of conditions associated with inflammation or excess angiogenesis or neovascularization, including age-related macular degeneration, cancer, stroke, and arthritis.
