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.

Eye Contact Avoided by Bipolar Children

eye contactA recent study showed that bipolar children spend less time making eye contact with people – looking at their eyes – versus typical children. Instead of looking at the eyes, bipolar children and children with severe mood dysregulation in the study spent less time looking at the eyes when observing faces. Instead, they spent more time with their eyes on the mouth and nose.

U.S. National Institute of Mental Health investigators suggested the eye contact habits of bipolar children as a possible explanation why these children have trouble determining  how other people feel.

This study has not yet been published in a peer-reviewed journal, so it should be considered preliminary. If accepted by the psychiatric community, this eye contact research may help develop treatment plans that education bipolar children guess the emotional state of people by looking more often at the eyes. In turn, they may process emotional information more accurately, which could help them regulate their feelings when interacting with others.

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.

 

 

Computer Vision Syndrome: Electronics Take Their Toll on Eye Health

Computer eye syndromeDo your eyes spend more than 4 hours a day looking at the screen of an electronic device? If so, you are at risk for computer vision syndrome. Computer vision syndrome symptoms include eye strain, fatigue, dry eyes and headaches from staring at a screen too long.

Are You at Risk?

To find out if you are at risk, keep a journal for a week of how long you spend watching TV, gazing at a smartphone, surfing the Internet, working on the computer, playing video games, and reading on a tablet device. The typical American youth is getting 7.5 hours of “screen time” a day – and since many adults use computers at work, they may get much more time.

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.

Strengthen Your Muscles from Your Eyes to Your Toes

exercise for the elderly including the eyesWhen you are in your 30’s, your skeletal muscle mass will peak. After that, they will reduce slightly in number and size every year. By the time you are in your 50’s, 15% of muscle mass may be lost, and by your 80’s, as much as 30% of muscle mass may be lost.

Obviously, strength training is crucial to strengthen your muscles and  increase their size. Being strong and fit helps maintain good health and energy, reduces osteoporosis and cardiovascular disease, burns calories for weight management, improves sleep, cuts cancer risk, and much more!

Everyone should make exercise a priority throughout their lives. However, up to 75% of older Americans do not get enough exercise.(1)

It is generally recommended that older adults should do strength training two or three times per week, performing 10-15 repetitions of approximately 8 to 10 different exercises.(1)

Drink Green Tea to Reduce Body Fat

Weight loss scaleDid you over-indulge in too many high-calorie foods over the holidays? Put on a few extra pounds? Two-thirds of American adults are overweight or obese, and a few extra pounds add up to health risks. However, drinking green tea may help fight body fat and also lower cholesterol levels.

Green tea is lower in caffeine than coffee, so it makes a great coffee substitute. A high intake of caffeine can cause nervousness, dependence, and sleep problems.

A recent, small study on green tea in Japan showed that taking green tea extract was associated with losing body fat and weight. The more green tea extract the study participants took, the bigger the effect. The subjects also had lower LDL cholesterol and lower blood pressure (to counteract hypertension).

Prevent Dry Eyes During Holiday Travel

traveling by air can resutls in dry eyes
Don’t let air travel dry out your eyes!

Does the idea of flying out to spend the holidays with family and friends make your eyes mist up?

Good! You’re going to need the moisture!

One of the biggest challenges with air travel is to prevent dry eyes. Why?

Low Humidity

You are probably used to a relative humidity above 40%. If you have a hygrometer or humidity sensor in your house, you are in the habit of monitoring your home’s relative humidity. When the humidity gets too low, such as in cold climates in the winter, you may experience dry eyes, sinus irritation and dry skin. Some homeowners install a humidifier in the winter to keep humidity at a comfortable level that does not allow mold growth, in the range of 40% – 49%.

The cabins in airplanes have relative humidity of 5% to 20%. This can lead to the surface of the eyes starting to dry out. Your eyes are naturally moistened by tears produced by the tear ducts. However, if the air on the outside of the eye is dry, moisture on the eye’s surface will start to evaporate more quickly than the tear ducts can produce moisture.

Inflammation of Eyelid Increasing in Frequency – About Blepharitis

blepharitis makes eyes sore
Blepharitis sufferers should not rub their eyes

Blepharitis is an inflammatory condition that affects lids of the eye. There are several types of blepharitis. Blepharitis can be caused by infections, allergies, irritations, insect bites, clogged oil glands in the eyelid, etc.

Symptoms vary, but can include swelling, itching, redness, blurry vision, irritation, scaling and crusty lashes. Blepharitis can occur alongside chalazions and styes. Only an eye doctor can accurately diagnose blepharitis, because its symptoms are similar to many other eye conditions.

The unfortunate fact about Blepharitis is that it is becoming increasingly common. Continue reading “Inflammation of Eyelid Increasing in Frequency – About Blepharitis”

Outdoor Activity Might Reduce Myopia in Children

outdoor time may reduce myopia in children and teensThe rise of myopia, also known as shortsightedness, has increased significantly in the past 30 years in the United States. Time spent outdoors has dropped off in this time period. Researchers at the National Eye Institute conducted a study of children and teens that shows a possible link between less time spent in outdoor activity and myopia.

In the early 1970’s, 25% of 12 to 54 year olds in the United States had myopia. In 1999-2004, that figure was 42%, a huge increase.

Myopia means that the eye focuses in front of the retina, making vision blurry. This condition is thought to be caused by Continue reading “Outdoor Activity Might Reduce Myopia in Children”
