Exercise May Be as Effective as Medication

Group Exercise 200A study in the British Medical Journal has shown that exercise can be as effective a treatment as conventional medication for some conditions. By examining 305 different trials, researchers found that patients that used exercise regularly as treatment rivaled or surpassed patients taking pills for the same conditions when examining their life expectancies.

The study was conducted by researchers at the London School of Economics, Stanford University School of Medicine, and the Harvard Pilgrim Health Care Institute at Harvard Medical School. Researchers scanned thousands of studies comparing exercise and medication and narrowed their analysis down to 305 of them. The cases included nearly 340,000 patients, treating conditions such as stroke rehab, heart disease and heart failure, and pre-diabetes.

Carotenoids & Coantioxidants for Macular Degeneration

Supplements 200Patients with early signs of age-related macular degeneration (AMD) may benefit from an oral treatment of key nutrients. In a study published in the journal Ophthalmology, a solution of carotenoids with coantioxidants was shown to both improve vision and slow further degeneration in participants with early AMD.
In the randomized double-masked trial, 433 adults with early AMD who were 55 years of age or older were given either an active solution or a placebo. At the start of the trial, all participants had either early AMD in one eye and late-stage AMD in the other, or early AMD in both eyes. The active oral solution contained Continue reading

Smart Glasses for Visually Impaired

TURN ON IMAGES to see man wearing high tech glassesResearchers at Oxford University have developed smart glasses intended to aid people with severe loss of sight. The glasses, which enhance an individual’s residual vision, are currently in trial, both in a closed obstacle course setting and in a “real life” trial in the streets of Oxford.

The smart glasses use a set of video cameras that record nearby objects and movement, which are projected onto the glasses lenses with the help of Continue reading

What is Optic Nerve Atrophy?

EyeOpticNerve200Optic nerve atrophy, also called optic neuropathy, is damage to the optic nerve from any cause. Some of these causes include: diabetes, glaucoma, certain health problems associated with aging, brain tumors, head trauma, infection, multiple sclerosis, radiation, inflammatory blood vessel diseases, sleep apnea, excessive blood coagulation, high cholesterol, genetic disorders, poisoning, malnutrition, and drug side effects. The optic nerve is the conduit between the retina of the eye and the visual processing center at the back of the brain. It contains 1.2 million nerve fibers that send sight signals to be processed by the brain. It is sheathed in the fatty nerve casing called myelin. Myelin protects nerves from damage and speeds nerve signals along. When it becomes damaged, nerves are exposed. Then they are very vulnerable to damage, much like an exposed Continue reading

Watch This Video on Macular Degeneration

macular degeneration video linkAge-related macular degeneration (AMD) is the most common cause of vision loss in adults over 55, but many don’t know the signs and risk factors of this common disease. In a new informative video on our AMD page, the process behind macular degeneration is explained with clear animation and up-to-date information so you can better understand this condition and help protect your eye health.

AMD occurs in the macula, the region of your eye responsible for your central, most exact vision. Hereditary, diet, and other factors can cause the breakdown of macular cells as an individual ages. For most, Continue reading

Oraya Therapy for Wet AMD Gains Popularity

orayaA one-time treatment for patients with wet age-related macular degeneration (AMD) is gaining popularity in Europe. Oraya Therapy, made by US-based company Oraya Therapeutics, Inc., is being offered at more locations in Europe, including a National Health Service hospital in the UK and several hospitals in Germany.

Oraya Therapy has already been a regular treatment option in hospitals throughout Germany, the UK, and Switzerland, increasingly embraced by patients, doctors, and insurance providers. The one-time treatment is a non-invasive therapy for wet AMD patients meant to maintain or improve vision and decrease frequency of anti-vascular endothelial growth Continue reading

Inflamed Eye Lids: All About Blepharitis

blepharitis-200Blepharitis is inflammation of the eyelids, and for many this is a chronic condition. It is a common condition that affects both adults and children. There are two kinds of blepharitis – anterior (front) and posterior (back) blepharitis. Anterior blepharitis affects the front of the eye, including the eyelid and eyelashes. It is often associated with a bacterial growth and/or an increase in the activity of the meibomian gland. Posterior blepharitis causes dry eyes and is created by the dysfunction of the meibomian gland. So it generally isn’t caused by a bacterial infection.

In the eyes, the meibomian glands (also called the “tarsal glands”) are a type of Continue reading

Exercise Improves Retinal Health

exercise eye diseaseResearch has shown that simple exercise could be the answer to improved retinal health and prevention of common eye diseases. Though exercise in general is regarded essential to overall health, for the first time a study has linked exercise directly with retinal health. This research could lead to better prevention and treatment of common retinal diseases, including age-related macular degeneration (AMD).

The study, titled “Aerobic Exercise Protects Retinal Function and Structure from Light-Induced Retinal Degeneration,” is the first Continue reading

Using the Eyes to Detect Diseases

eye-detect-200The eyes are not just the mirrors of our souls – they also reflect many of our diseases. Because they are the only place in the body where you can easily see blood vessels and even part of the brain via the optic nerve, they can be used to detect a number of diseases.

A large study of 120,000 people by the insurance company, VSP Vision Care, found that 34% of diabetes patients first found out about their disease from an eye exam. High blood pressure Continue reading

How to Gain Optimal Vitamin D Levels from the Sun

vitamin d from sunVitamin 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 Continue reading
