Does Nutrition Underlay the Pathogenesis of Glaucoma and Cataract in Ageing?

World Health Organization has been reported glaucoma, cataract, diabetic retinopathy, agerelated macular degeneration, and trachoma as major causes for visual impairment. Among them, cataract remains the major avoidable blindness. The risk for cataract gradually increases in elder adults. More than 82% of people above the age of 50 years are under the risk for visual impairment [1]. Nutrition is one of the important determinants of health is often under diagnosed over the age of 65 [2]. Though no uniformly accepted definition for malnutrition has been described in the elder people, certain indicators had already been described for a specific vitamin deficiency [3]. During the last decade several studies had suggested the nutritional deficiency of certain vitamins and supplementation of iron as the modifiable risk factor for visual morbidity in the elder people.
