Glaucoma refers to numerous eye conditions that cause damage to the optic nerve--the nerve responsible for sending visual information from the eye to the brain. According to the University of Maryland Medical Center, glaucoma is the second leading cause of blindness in the United States. Treatment for glaucoma may include eye drops, laser treatment or surgery. Certain foods and nutrients may help strengthen eye health and reduce problems associated with glaucoma. For best results, a doctor's guidance is recommended.
Lutein and Zeaxanthin
The eyes contain rich amounts of the nutrients lutein and zeaxanthin. According to the Glaucoma Research Foundation (GRF), lutein and zeaxanthin may play significant roles in protecting the eyes from eye conditions, including cataracts and glaucoma. Lutein and zeaxanthin also provide antioxidant properties, which can strengthen a person's immune system and their ability to prevent or combat infections and disease. Leafy greens, such as spinach, kale, cooked mustard greens and cooked collard greens, provide rich amounts of lutein and zeaxanthin. Modest amounts of the nutrients can be reaped from peas, corn, green beans, broccoli, papaya, eggs and oranges. Lutein and zeaxanthin are also available in dietary supplements.
Vitamin C
Vitamin C, also known as ascorbic acid, is a water-soluble nutrient with potent antioxidant properties. Sufficient intake may support eye health, prevent or reduce glaucoma, and promote overall wellness. Valuable sources of vitamin C include red bell peppers, oranges, grapefruit, tangerines, strawberries, blueberries, tomatoes, kiwifruit, cantaloupe, brussel sprouts, potatoes, cauliflower and spinach. It can also be reaped from vitamin-fortified cereals and beverages and in dietary supplements. The Office of Dietary Supplements (ODS) recommends at least 90 mg of vitamin C daily for men, and at least 75 mg daily for women.
Zinc
Zinc is an essential mineral that supports normal cell function, wound healing and immune system function. According to the GRF, sufficient zinc intake may prove beneficial for people with or at risk for glaucoma. Zinc is prevalent in oysters, pork, chicken, lobster, baked beans, cashews, yogurt, raisins, chickpeas, almonds, various cheeses and most vitamin-fortified cereals and beverages. According to the ODS, most adults require 40 mg of zinc daily. Since excessive zinc intake through dietary supplements may cause toxicity, ideal intake is attained through food. However, doctors may prescribe zinc supplements for people with known zinc deficiency.
