omega-3 and omega-6 long-chain PUFAs and their enzymatic metabolites in neovascular eye diseases

• Neovascular eye diseases, including retinopathy of prematurity, diabetic retinopathy, and age-related macular degeneration, threaten the visual health of children and adults. Current treatment options, including anti-vascular endothelial growth factor therapy and laser retinal photocoagulation, have limitations and are associated with adverse effects; therefore, the identification of additional therapies is highly desirable. Both clinical and experimental studies show that dietary omega-3 (n-3) long-chain polyunsaturated fatty acids (LC-PUFAs) reduce retinal and choroidal angiogenesis. The omega-3 LC-PUFA metabolites from 2 groups of enzymes, cyclooxygenases and lipoxygenases, inhibit [and the omega-6 (n-6) LC-PUFA metabolites promote] inflammation and angiogenesis. However, both of the omega-3 and the omega-6 lipid products of cytochrome P450 oxidase 2C promote neovascularization in both the retina and choroid, which suggests that inhibition of this pathway might be beneficial. This review summarizes our current understanding of the roles of omega-3 and omega-6 LC-PUFAs and their enzymatic metabolites in neovascular eye diseases.
