[Omega-3 nonsaturated fatty acids: role in pathogenesis of ocular diseases and perspective in ophthalmology].

It is showed that the main functions of nonsaturated fatty acids (NSFA) are participation in cell membrane phospholipids formation and synthesis of icosanoids (tissue hormones): prostacyclines, prostaglandins, leukotrienes and thromboxanes, that take part in regulation of local cell and tissue functions, including inflammation, activity of platelets, white and red blood cells, dilatation and constriction of vessels. NSFA consumption was proved to be associated with age macula degeneration. Maximal intake of long chain Omega-3 NSFA reduces the chances of end stages development by 30%. Nutritional supplement containing Omega-3 NSFA is an additional treatment and promising option for treatment of blepharitis, meibomian gland disfunction and dry eye syndrome.
