Breakthrough Prosthetic Sends Retina Signals to Brain to Restore Sight

blind mice had their vision restorated with new technologyBreakthrough research into vision restoration may result in a new type of prosthetic for people suffering from vision loss due to retinal degenerative diseases such as macular degeneration and retinitis pigmentosa.

Researchers cracked the retinal code that the retina uses to communicate with the brain. Their initial research was on mice. They determined which electrical signals the retina uses when communicating with the brain. Then, they mimicked the signals using electric-signal sending glasses in blind mice. The animals’ vision was restored to near normal.

Targeted Nutrients May Help Migraine Headaches

occular migraines is a type of migraine headacheEveryone who suffers from migraine headaches wants to know how to prevent their next migraine. Recent strong research has resulted in guidelines for doctors to help prevent their patients’ future migraines, including the use of herbs, vitamins and minerals. The guidelines make recommendations for specific types of patients, such as patients with certain other conditions, obese patients, new migraine patients, and pregnant/lactating women.

This research, conducted by the Canadian Headache Society, reviewed a large body of double-blind studies according to standardized criteria. They also did a general literature review and got expert consensus for aspects of prophylactic (preventative) migraine therapies that did not have randomized clinical trials.

Age-Related Macular Degeneration Helped using Astaxanthin

Krill is a source of astaxanthin for the eyesAge-related macular degeneration is a serious and common eye ailment in the aging population, but an Italian study showed that taking just 4mg of astaxanthin per day mitigated the symptoms.

ARMD — Age-Related Macular Degeneration –  is the gradual breakdown of the cells of the macula. The macula a small, yellow-colored part of the eye that is near the center of the retina. When this breaks down, central vision is compromised. People with ARMD often have difficulty recognizing faces, reading, writing, and driving. Peripheral vision is unaffected.

Age-Related Eye Disease Prevention

Older adult may face eye disease with agingAs people age, eye diseases and conditions that commonly occur include macular degeneration, cataracts, vitreous tears/retinal tears and detachments, glaucoma, diabetic retinopathy, dry eyes, and eye floaters.

The question arises as to whether eye disease is inevitable with age. Will all older adults eventually have a “glint” in their eyes after cataracts surgery? More than 50% of people aged 75+ have glaucoma, cataracts, or macular degeneration. Can aging adults do anything to prevent, manage or slow down eye diseases associated with aging?

A large body of research is accumulating that shows the effects of regular eye exercises, good nutrition, and targeted supplementation on preventing and/or managing eye conditions. For instance, peer-reviewed research has shown that the risk of getting macular degeneration can be significantly reduced by taking fish oil and lutein on a daily basis. Vigorous exercise may reduce the incidence of glaucoma. And the effects of antioxidants on preventing cataract and macular degeneration have been the subject of significant research.

Carotenoids Absorbed Better When Taken with Fat

salad vegetables high in carotenoidsA new study demonstrated that adding oil or fats to your salads and vegetables increases the body’s ability to absorb vision-boosting lutein, lycopene, beta-carotene, zeaxanthin and other carotenoids. Carotenoids are a family of nutrients that absorb blue light. They are naturally colored in the yellows and reds on the light spectrum.

The study in the Journal Molecular Nutrition & Food Research showed that monounsaturated fats allowed for the best absorption of carotenoids. Carotenoids are antioxidants that are associated with reduced risk of major diseases afflicting Westerners including CV – heart disease and cardiovascular disease, cancer and macular degeneration. Another study showed that supplementing with a carotenoid in the family of lutein called zeaxanthin improved vision in elderly adults with macular degeneration.

Many natural foods are rich in carotenoids. Here are some recipe ideas:

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.

ReVision Formula Uses Classic Chinese Medicine for Liver to Improve Eyes

ReVision formula addresses chi for the eye using classic Chinese medicineWhat is ReVision formula, and how can its classic Chinese medicinal ingredients help improve eye health and conditions such as eye floaters? ReVision formula is a liquid taken orally several times per day with water. This tincture is based on Rambling Powder, also known as Xiao Yao San.

ReVision Formula is designed to support healthy vision. Some of the conditions it may address include macular degeneration, eye floaters, and glaucoma. The idea is that ReVision Formula helps improve blood circulation to the eye. From the point of view of Chinese medicine, it helps eliminate stagnation of the body’s energy (chi) to the eyes.

Natural Curcumin Beats Drug for Rheumatoid Arthritis in Study

Curcumin from turmeric may help rheumatoid arthritisA pilot study published in Phytotherapy Research compared curcumin – derived from natural turmeric – with the drug diclofenac for treating rheumatoid arthritis (RA). Natural curcumin actually reduced RA symptoms even better than the RA drug diclofenac: a 44% reduction in symptoms on the Disease Activity Score and the American College of Rheumatology criteria for reduction of swelling and tenderness of joins. Patients receiving diclofenac had a 42% reduction.

This is good news because curcumin has no known side-effects. Using anti-inflammatory medications over the long term sometimes has side effects that can result in stomach ulcers and damage to the kidneys. The extremely popular non-steroidal anti-inflammatory medication Vioxx (Rofecoxib – $2.5 billion in sales in 2003) was removed from the market in 2004 due to increased risk of heart attacks and stroke.

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.

Experimental Electronic Retinas Implanted in Two Patients

electronic retinal implantTwo men blinded by retinitis pigmentosa have had their sight partially restored by receiving electronic retinal implants at King’s College Hospital in England.

The surgery involves implanting a 3×3 mm2 microchip with 1,500 electrodes below the retina. A thin cable is run to a special sub-dermal control unit that is implanted behind the ear. When light reaches the eye, pixels in the chip are stimulated, sending electronic signals to the optic nerve and then to the brain. An external power unit can be connected to the chip using a magnetic disk implanted on the scalp. This allows the chip’s sensitivity to be altered.

Clinical trials began more than 6 years ago. The technology is improving over time, with the more recent patients reporting better visual acuity.
