DHA Shown To Prevent Age-Related Macular Degeneration

Fish contain DHA an Omega 3 fatty acidA breakthrough laboratory study has found that DHA, an Omega 3 fatty acid, prevented Age-Related Macular Degeneration (ARMD).

A Canadian research team at the University of Alberta Faculty of Medicine and Dentistry fed DHA to mice and measured the levels of a toxin called lipofuscin. Lipofuscin builds up in the eye with age, causing ARMD. Mice who ate the DHA for at least 6 months had significantly lower levels of the toxin.

Age-related macular degeneration affects around nine million adults aged 40+ in the USA. ARMD can cause serious loss of vision. It affects the central part of vision, not peripheral vision. Deterioration of the cells in the macula at the eye’s center makes reading, writing, and driving difficult.

High-tech Goggles Plus Surgical Implant May Help Restore Sight to Blind

solar prosthetic vision design from the article in Nature Photonics May 2012Experimental research at Stanford University school of medicine may result in the restoration of vision for people whose sight has been lost due to Age-Related Macular Degeneration (ARMD), Retinitis Pigmentosa and other diseases of the retina. Surgeons plan to implant small solar panel-like cells under the retina. When the patient wears a special type of goggles, a camera and small computer will allow them to see the world around them again.

The goggles will have a tiny camera and a small computer. The computer will process data from the camera and display images on an LCD (liquid crystal micro-display) on the goggles. The images on the LCD are beamed using laser pulses of IR-A (near-infrared) light to tiny photovoltaic silicon chips implanted under the retina. The electrical currents from the chips’ photodiodes would trigger signals in the retina. From the retina, the message would flow to the brain, giving the patient the ability to see.

Age Related Macular Degeneration in Women Mitigated by Omega-Fatty Acids

Fish may prevent age related macular degeneration AMD or ARMDA research study published in Archives of Ophthalmology showed that ingesting omega-3 fatty acids and fish affects the incidence of AMD (age-related macular degeneration, or ARMD) in women. This large study (nearly 40,000 participants) over 10 years found that women who had the highest of intake of Docosahexaenoic acid (DHA, an omega-3 fatty acid) had the lowest risk of AMD versus subjects with the lowest intake. Women who ate at least one serving of fish per week had a relative risk of AMD of 0.58 compared with women who ate less than one serving per month.

This was a retrospective study that involved 39,876 female health care workers completing food frequency questionnaires. At the beginning of the study, none of them had ARMD. 265 developed age-related macular degeneration by the end of the ten-year study. Few regular fish eaters developed the disease, but the ladies who skimped on fish were significantly more likely to get AMD.

Vision Improved in Macular Degeneration Patients with Nutrition

peas contain important nutrientsA new study published in the November 2011 Journal of Optometry confirms improved vision in elderly patients with early Macular Degeneration through nutritional supplementation with Zeaxanthin (a carotenoid in the family of lutein).

The Zeaxanthin and Visual Function Study (ZVF), conducted by eye nutrition pioneer Stuart Richer, PhD, OD at the Veterans Administration Hospital in Chicago, shows scientific evidence that dietary Zeaxanthin improved vision in night driving and fine detail, among others.

Age-related Macular Degeneration May Be Helped with Melatonin in Research Study

age-related macular degeneration is a leading cause of serious vision loss and blindness in the elderlyA study indicates that melatonin supplements may slow and even reverse the effects of age-related macular degeneration (ARMD). ARMD is the leading cause of serious vision loss in elderly persons.

The symptoms of ARMD include seeing wavy lines that should be straight, blurred text, and/or dark or empty spaces in the center of the field of vision. The cells that sense light in the eye’s macula stop functioning correctly and after some time, they do not work at all. A simple visual test called the Asmler grid is an effective screening for age-related macular degeneration.

Grapes May Prevent Age-Related Macular Degeneration

grapes have anti-oxidant effects on the eyesA new study in the journal Free Radical Biology & Medicine compared the effects of lutein to grapes on the eyes. Grapes won out, providing more protection against oxidative damage to the retina than the nutrient lutein.

Mice were broken into two groups: on had a diet high in grapes, and the other received lutein, a plant chemical that recommended for eye health. The mice who ate grapes were less likely to go blind.

Grapes are rich in anti-oxidants, which fights free radical damage.

The study’s head author, Dr Silvia Finnemann from Fordham University, described the results as “remarkable” and wrote, “A lifelong diet enriched in natural antioxidants, such as those in grapes, appears to be directly beneficial for RPE (retinal pigment epithelium cells) and retinal health and function.”

Some diseases that result in damage to the retinal pigment epithelium (RPE) layer in the eye include Stargardt’s disease and age-related macular degeneration.

This study does not diminish lutein as an eye care supplement. A solid body of scientific research shows lutein’s benefits. Lutein also has antioxidant properties; grapes had  a stronger effect in mice in this single study. Lutein is found in the macula of healthy eyes, and research shows that taking 6 mg of lutein each day reduces the risk of macular degeneration by 48%. Learn more about lutein for eye care.

 

 

Incidence of Blindness Drops in Denmark Due to Treatment of Wet AMD

blindnessIncrease in the delivery of a treatment for neovascular age-related macular degeneration (wet AMD) has resulted in a significant 50% reduction of new cases of blindness in Denmark, according to a study published in the American Journal of Opthamology. Age-related macular degeneration is the most common cause of blindness in the West. Specifically, AMD patients lose reading vision and their ability to drive, resulting in revocation of their drivers’ license.

Wet AMD is the most serious type of macular degeneration. Abnormal blood vessels start  to grow in the eye, toward the yellow spot in the middle of the retina called the macular. The macular provides the most visual acuity, as well as perception of color. Wet AMD results in quick and severe loss of vision.

Baby Boomer Natural Eye Care in the 21st Century

As the “Baby Boomer” generation in the United States approaches their 60’s and beyond, the incidence of eye disease in this aging population will rise. Eye problems become more prevalent as an individual ages. What are the most common eye diseases in older people? How can eye geriatric eye disease be prevented and addressed naturally? And what does Baby Boomer natural eye care look like?

Macular Degeneration

A major reason for visual impairment and blindness in adults aged 50+ is Macular Degeneration, also known as ARMD (Aged-Related Macular Degeneration). Vision in the center of the visual field is impaired, but peripheral vision remains. People with macular degeneration have difficulty writing, driving, recognizing faces and reading. Symptoms include:

  • Colors look dim
  • Words appear blurred or difficult to read
  • Straight lines look wavy
  • Dark or blank areas block the center of your vision
  • Distinct shapes are blurry
  • Fog in the center of your vision

Anyone with any of these symptoms should Continue reading “Baby Boomer Natural Eye Care in the 21st Century”

Macular Degeneration Twins Study Results

A diet that includes vitamin D, betaine and methionine can help to lower your risk of developing macular degeneration (AMD).  A study of identical twins conducted by the Tuft Medical Center also supports the assertion that smoking increases one’s chance of getting AMD.

AMD tends to run in families, and this opportunity to look at twins who exhibit different stages of the disease allowed researchers to zero in on how diet and lifestyle habits affected the condition’s progression.

According to the source of this story, Science Daily, Vitamin D, which is added to many milk products, may reduce the risk of AMD because it has anti-inflammatory properties.  Betaine (contained in fish, grains, and spinach) and methionine (found in poultry, fish, and dairy products) both seem to work at the DNA level to slow the progression of the disease.

This study was published in the July 1 issue of Ophthalmology.
