As we age, our chances of developing a serious vision problem increase significantly. More than half of people over the age of 70 years old have an eye condition such as cataracts, glaucoma, and macular degeneration; people with diabetes often develop diabetic retinopathy. These limiting conditions decrease the quality of life. Being a retired senior means having time to enjoy life, read, travel, play golf, enjoy hobbies, and socialize with friends and family. However, participating in these activities requires clear vision.

We can learn to help preserve our vision and to become active

Stargardt’s Disease and Retinitis Pigmentosa are genetic eye diseases that involve the metabolism of vitamin A. However vitamin A has a different impact on the course of each disease. A recent study¹ examined the total intake of vitamin A in both types of patients. It found that:

• Stargardt’s patients with high A intake had low visual acuity

Rod-Cone Dystrophy is a genetically-based deterioration of vision caused by damage to the photoreceptors in the eye. Rods and cones are the photoreceptor cells in the retina that give us daytime and night time vision. Genes that provide the blueprint for manufacturing proteins crucial to the eye’s rods and cones are damaged. Without enough of these proteins, vision deteriorates and blindness may result.

Much of the current research into rod-cone dystrophy is focused on genetic research. Scientists are busy identifying the faulty genes and how they function. Stem cells or other genetic therapy offers hope for a treatment and possibly cure in the future. In the meantime, nutritional and lifestyle choices may

Age-Related Macular Denegation is a significant cause of vision loss that can often be managed and even improved through targeted nutritional support. It affects mostly people over age 50. While the precise cause of ARMD is not clear, oxidative damage is suspected as being a major factor. It strikes the elderly possibly due to poor diet and nutritional intake over a lifetime, less efficient absorption of nutrients and poor circulation as the body ages. The care needed by vision-impaired elderly could become overwhelming. Let’s take a look at some of the newest research in preventing macular degeneration, as well as treatment and support options.

Women with specific genes may be more likely to develop age-related macular degeneration (AMD) if they are deficient in Vitamin D, according to new research in JAMA Ophthalmology.

The genetic variant (Y402H) studied is the complement factor H gene, called CFH for short. The genes in question are related to the immune system. The development of macular degeneration is believed to involve inflammation. In AMD, drusen, lipids (fats) and proteins build up in the eye. The body perceives the drusen to be an invader and attacks it. The genes appear to cause a stronger immune response.

Vitamin D is responsible for overall immune system health as well as vastly reducing the risk of numerous chronic diseases and cancers. The best way to receive vitamin D3 is through the sun, but it is essential to achieve a fine balance between healthy exposure and overexposure.

UVB rays from the sun present an unusual contradiction. They are the wavelength that can quickly cause sunburn on the surface of the skin, but they are also essential to vitamin D production. The body requires sun exposure to convert a cholesterol derivative into vitamin D3.

In order to gain safe and adequate exposure to UVB, a

Vitamin A deficiency is uncommon in the U.S., but it affects many people in the developing world.  One of first symptoms of a vitamin A deficiency is night blindness, which, if untreated can develop into full scale blindness.  According to the World Health Organization Report on Vitamin A Deficiency, night blindness is estimated to affect 5.2 million preschool-age children and 9.8 million pregnant women around the globe.

Writing on a case in The Lancet, doctors who treated a pregnant woman who came to the emergency room after several weeks of progressive sight loss described this particular case, “Vitamin A deficiency can be secondary to poor intestinal absorption due to weight loss surgery, Crohn’s disease or pancreatic dysfunction. Our patient had anorexia nervosa and had limited her diet to white onions, white potatoes, and red meat for the past 7 years.”

 Homocysteine is an amino acid that can be measured with a simple blood test. The study, which appeared in the Journal of Affective Disorders in August 2013, studied 358 people aged 50 and up who had symptoms of depression.

They gave the subjects cognitive tests that looked at immediate and delayed memory, as well as global cognitive performance. They measured

In a recent study, hospital patients with higher levels of the vitamin were less likely to develop hospital-acquired bloodstream infection (HABSI).

This protective effect of vitamin D is an important finding. Boston researchers collected data from 2,135 patients of Boston hospitals from 1993 to 2010. The men and women had vitamin D levels measured before admission to the hospital. 48 hours after admission, their blood samples were
