Breakthrough 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.
Did you know that the leading cause of blindness in children is eye inquires, and that most eye injuries in schoolchildren are sports-related? According to The National Eye Institute, the damage from eye injuries can be temporary or, or they can lead to permanent loss of vision.

A new review has revealed that thousands of patients in UK care homes (nursing homes) are missing out on sight tests and acceptable standards of eye care. The review, compiled by the Thomas Pocklington Trust and the International Longevity Centre UK, claims that up to half of the 400,000 elderly people living in UK care homes suffer from sight loss that could be treated. Diseases prevalent in the elderly include glaucoma, cataracts, and macular degeneration. However, eye health is being neglected in the majority of homes, with some carers assuming that there is no need for sight testing in elderly patients, especially in the case of those with Alzheimers Disease (dementia), and a lack of national policy is causing eye care to fall low down on the list of care priorities.

Age-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.
The sun represents a potential threat to the eyes. Overexposure to sunlight can cause an increased risk of cataracts, cancer of the lids of the eyes, and even cornea burns. It is important to prevent eye disease and injury caused by UV radiation and sunlight.
Dr. George Cioffi is the chief of ophthalmology at New York-Presbyterian Hospital/Columbia University Medical Center. He points out that people at elevated risk of eye damage from the sun include cataract surgery patients, people with light colored eyes, patients who have disorders of the retina, and patients whose medications cause sensitivity to light.
As 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.
The obesity epidemic may have an impact on the health of the eyes. While scientific studies do not seem to have found a direct link between obesity and eye disease, maintaining a healthy weight supports your overall health and helps prevent diseases that can harm the eyes. Here’s why.
Obesity is a step up from “overweight.” The National Institute of Health (NIH) in the United States, commonly uses Body Mass Index (BMI). This is a ratio of height to weight. Overweight is a BMI of 25-29, and obesity is a BMI of 30 or more. For example, 5′ 7″ person who weighs 160 pounds would have a BMI of 25 (just barely overweight). This same person at 195 pounds would have a BMI of 30 (obese) and at serious risk of disease such as heart disease, cardio-vascular disease, stroke, cancer, diabetes and lower-body joint problems.
Drug maker GlaxoSmithKline has been found guilty of fraud in the way it reported research on, or marketed, on 3 of its medications in the largest settlement against a drug company in US history–$3 billion. The issues involved 10 drugs, and included marketing “off-label” use of the antidepressants Paxil and Wellbitrin and the asthma drug Advair, and not reporting all the safety data for the diabetes drug Avandia.
GlaxoSmithKline pleaded guilty and agreed to pay $3b total in both criminal fines and civil settlements with the federal and state governments. The fines will be paid next year.
In a press conference, Deputy US Attorney General James Cole said the settlement was “unprecedented in both size and scope.”
Want to reduce your risk of glaucoma? Stay physically active. A study in the Investigative Ophthalmology & Visual Science Journal showed that higher levels of activity seems to have a beneficial impact on ocular perfusion pressure (OPP). OPP is a crucial risk factor for developing glaucoma.
The study was done on 5,650 adults aged 48-90 in the U.K. It measured the relationship between current OPP and physical activity over time. The subjects filled out lifestyle and health questionnaires. The surveys recorded how much physical activity the subjects got during both work hours and leisure time. They were given tests to measure eye pressure (intraocular pressure — IOP) and blood pressure.
This study showed a 25% reduced risk of low OPP in study participants who had moderate physical exercise approximately 15 years before.
Standard glaucoma treatment depends on adherence to a program of medication and medical appointments. A recent study indicated that an interactive, automated series of phone calls to glaucoma patients increased compliance with their treatment. However, the control group who received no calls had equally good compliance, indicating further research is needed.
The lowest glaucoma treatment compliance rates are typically found among African Americans and patients who do not understand the importance of treating glaucoma over the long term. This study was conducted on 312 patients at an eye clinic at a large public hospital and at a Veterans Affairs facility eye clinic. They were mostly male and African American, with an average age of 63, and had a history of not taking their medication regularly, not refilling their prescriptions, and not keeping all the recommended medical appointments.

NaturalEyeCare™ started in 1999 to help the public and professionals learn about complementary care in eye disease treatment.
The information and recommendations we offer are based on over 30 years of peer review research and personal clinical experience which guides us in providing a valuable resource to our readers, customers and patients regarding maintaining healthy vision naturally.
We believe that vision health is intimately connected to overall mental, physical and spiritual health. Therefore we encourage people to look at their overall lifestyle and diet as part of keeping healthy vision and reducing the risk of eye disease onset. This includes diet, regular exercise, and management of daily stress. If one has health issues such as high blood pressure, a thyroid imbalance, any autoimmune disease and/or are on medication(s), these possible contributions to eye disease should considered when working with your health care professional.
Please do not hesitate to call us at 845.475.4158 with any questions and concerns.
