Abstract

Nutrition is a subject of interest in many fields of medicine. So ophthalmologists have also attempted to find possible ways to preserve vision through diet and supplements. Ocular disorders such as cataracts, age-related macular degeneration and glaucoma are the leading causes of visual impairment and blindness in the world, so most of the studies have focused on these major disorders and nutritions containing antioxidant such as vitamin C and E. Zexanthin/luteins and omega 3 have been the main substances studied in this relation. Although benefits of the regimens with high amounts of antioxidants were observed in reducing progression of cataract, age-related macular degeneration and so on, as many of these studies have been observational, the cause and effect relationship cannot be definitely concluded and multiple cohort prospective studies will be desired to evaluate the exact role of nutrition. Somehow, a healthy diet which means the diet which increases our health can be achieved in regimens with low saturated fatty acids and rich in fresh fruits, vegetables and fish. On the whole, even though they may not affect disease progression, they are generally good for overall health.
