ZINC AND AGE-RELATED MACULAR DEGENERATION Zinc supplementation has been found to help reduce the risk of age-related macular degeneration in some studies. Other studies have not shown a connection between dietary zinc intake and the incidence of age-related macular degeneration. Zinc is found in high concentrations in the macula (central) portion of the retina. Zinc concentration in this area of the eye has been found to decrease with aging. Current research is trying to find out if zinc and antioxidant supplementation can help reduce the effects of age-related macular degeneration.

DIAGNOSIS One of the most common problems associated with eyes is the slow progressive loss of vision, known as age-related macular degeneration. This condition begins with the deterioration of the retina, gradually resulting in blurred vision and a difficulty reading, and eventually leading to a blind spot in the center of the visual field. It is the leading cause of eye problems in people over 60 years old. Risk factors include smoking and not protecting the eyes adequately from bright sunlight. The condition usually starts in one eye and then eventually affects the second eye as well.

Indeed, in most cases, phantom visions are signs of poor or deteriorating eyesight or other eye problems, such as glaucoma, cataracts, and especially age-related macular degeneration (AMD). AMD is a very common and serious degenerative eye disease that is the leading cause of vision loss in adults. Women, whites, people with light-colored eyes, smokers, and the obese are at increased risk. AMD also appears to run in families. The famous 19th-century English poet Alfred Lord Tennyson was said to have suffered from failing eyesight, floaters, and phantom visions. "These animals...

Lutein description Lutein is a naturally occurring carotenoid used to improve eye health, especially in people with age-related macular degeneration (ARMD) and cataracts. Studies show that the retina selectively accumulates two carotenoids, lutein and its chemical cousin zeaxanthin. Within the central macula, zeaxanthin is the dominant component (up to 75%), whereas in the peripheral retina, lutein predominates (greater than 67%). The macular concentration of lutein and zeaxanthin is so high that they are visible as a dark yellow spot called the macular pigment.

This chapter addresses the influence of diet on the most common causes of vision loss in middle-aged and older people: age-related cataract, age-related macular degeneration, and diabetic retinopathy. Significant advances in the understanding of how nutrition may influence eye diseases of the aging population have been made since the 1980s. The aging public's awareness of the decline in vision with age, and of the possibility that nutrition may influence this decline, has driven the marketing of nutritional supplements, which are sometimes costly and of uncertain benefit.

Macular Degeneration Zinc supplementation has yet to be proven useful in age-related macular degeneration (ARMD). Prospective, randomized, controlled trials have been conducted investigating the role of zinc in ARMD using doses 5.3 times the RDA of zinc for men and 6.7 times the RDA of zinc for women. Beneficial results from one small trial could not be confirmed in the much larger AREDS trial (see below), which failed to find a significant reduction in visual acuity loss after zinc therapy.

However, a preliminary study found no association between age-related macular degeneration and intake of antioxidants, either from the diet, from supplements, or from both combined.20 Moreover, in a double-blind study of male cigarette smokers, supplementing with vitamin E (50 IU per day), synthetic beta-carotene (about 33,000 IU per day), or both did not reduce the incidence of age-related macular degeneration.21 Two important enzymes in the retina that are needed for vision require zinc (page 614).

DECREASED RISK OF AGE-RELATED MACULAR DEGENERATION: Phytochemicals such as lutein, cryptoxanthin, and zeaxanthin, present in papaya, may help maintain better eyesight longer in older people. Tips on Using Papaya SELECTION AND STORAGE: • Papayas that are hard and green are immature and will never properly ripen. Look for papayas that are mostly or completely yellow. • The papaya should give slightly to pressure, but should not be soft at the stem end. • Avoid buying fruit that is bruised, shriveled, or has soft spots.

Macular Degeneration In the United States, age-related macular degeneration (ARMD) is the leading cause of blindness in people more than sixty years old.' For those who are not familiar with this disease, it is a decay of a critical part of the retina called the macula. This is where the greatest concentration of photoreceptors is located and is the area responsible for central vision. When this area of the eye begins to decline, we essentially lose central vision, our most important aspect of sight.

Mechanism of injury to the Retina In recent years several researchers have made interesting proposals as to the actual cause of age-related macular degeneration (ARMD). These theories suggest that light that enters the eye and is focused on the macula of the retina causes significant free-radical production in the outer aspect of these photoreceptors. Again, if antioxidants are not available to readily neutralize these free radicals, the free radicals can cause damage to the photoreceptors.

Dietary Fat There are at least three broad mechanisms by which dietary fats might either enhance or slow age-related macular degeneration: first, because of the high caloric density of fats, eating high-fat foods can displace other nutrient-dense foods that may have otherwise protected against AMD. Second, eating high-fat and low nutrient density foods may contribute to high body mass, which is sometimes reported to be a risk factor for AMD [185-187]. Third, fatty acids themselves have numerous biological effects as components of biological membranes and regulators of biochemical pathways.
