Medical Marijuana and Glaucoma: Does It Help?

medical marijuana for glaucomaYou may have heard that medical marijuana is sometimes used by glaucoma patients. When most people in the United States think of marijuana, many different images, words, and opinions come to mind. Marijuana, or cannabis, is known for its psychoactive effects and medicinal properties caused by a chemical within the plant called tetrahydrocannabinol, also known as THC. Marijuana is most commonly recognized as a recreational drug and is subject to many legal restrictions ranging from its use, to possession of certain amounts of the plant product.

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.

Eye Health Being Neglected In UK Care Homes

Eye health at elderly care homesGuest Blogger, Richard Keane

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.

Why is eye health being neglected?

The review cites a number of possible reasons for eye care neglect: firstly, eye care is not usually considered a threat to overall health and as a result it comes low on the list of priorities for care givers and nurses in nursing homes. Nurses are currently overstretched and they use their time to identify and treat problems they deem more harmful.

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.

Obesity’s Effects on Diabetic Retinopathy, Cataracts and Eye Disease

effect of obesity on eye healthThe 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.

Record-breaking Fine Against Drug Company GlaxoSmithKline

Drug company finedDrug 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.”

Glaucoma Risk Reduced by Exercising

exercise seems to reduce the risk of glaucomaWant 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.

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.

Forty Percent of Cancers Caused by Lifestyle

Alcohol is a preventable cause of cancerA recent UK research study shows that 40% of all cancers are caused by avoidable lifestyle considerations, such as diet, excess weight, smoking, and/or alcohol consumption. Tobacco use was shown to cause the most cancers.

“Many people believe cancer is down to fate or ‘in the genes’ and that it is the luck of the draw whether they get it,” study author Professor Max Parkin, a Cancer Research UK epidemiologist based at Queen Mary, University of London. The reality is, based on the study, that many cancers can be avoided through lifestyle changes.

The research showed that in Britain:
