Retinal enrichment in omega-3 polyunsaturated fatty acids limits choroidal neovascularization

2016

International audience; Purpose: Age-related Macular Degeneration (AMD) is the primary cause of blindness in elderly population of western countries. Prospective epidemiologic studies have reported that omega-3 polyunsaturated fatty acids (PUFAs) reduce the risk of progression to advanced AMD, and particularly to the neovascular forms. In this study, we have investigated the beneficial effects of omega-3 PUFA on choroidal neovascularization (CNV) in mice.Methods: Fat-1 mice, endogenously converting omega-6 to omega-3 PUFA, and littermate controls were used at 4 months of age. CNV was induced unilaterally in eye fundus by photocoagulation using a 532-nm laser. Confocal scanning laser ophthal…
