AMD and a Healthy Diet: How they Relate

While there is still no concrete answer as to why some do not develop age-related macular degeneration (AMD) and other’s do, significant studies have proven the importance of a healthy diet and the mitochondria.

AMD is the leading cause of vision loss for those over 60 years of age in the developing countries. For decades we have studies that show the genetics and environmental factors associated with AMD. There have been over 20 genetics modification associated with AMD but there is no single gene that “causes AMD in all cases.” The genes most highly associated with AMD are found in the complement system, an important system related to controlling the inflammation in our body. A change in the complement factor H (CFH) gene from a low risk gene to a high risk gene has been associated with 43% of those developing AMD.

However, some people who have this high risk CFH gene but never develop AMD. This leads us to believe that the genetics are not the entire answer. The other factor has to do with the environment. Smoking is the leading risk factor, along with aging, exposure to sunlight and higher body mass index (obesity). But again there are obese people that smoke and never develop AMD. So, while the environmental risk factors are important, they do not answer the entire question of “why do some people get AMD but others do not?”

Recently, researchers have recognized that a major factor in the dry form of AMD is that the retinal cells begin to die off. Therefore, they have looked at important factors that keep cells alive. The mitochondria are one of the most important elements that protect the cells in the body. These subunits or organelles, produce energy for the cells, acting like batteries for the cells. And just like the batteries in a flashlight – if the batteries are not working then the flashlight dies. The same thing happens with cells – when the mitochondria are not healthy, then the cells eventually will die. Therefore to protect ourselves, it is important to keep the mitochondria healthy. One way to do this is to eat healthy foods. Over the past 20 years, the National Eye Institute (NEI) has conducted a series of studies that have identified foods and supplements that are good for the retinal cells and also the mitochondria.

 

super greens, spinachThe National Eye Institute has recommended that people who are high-risk for developing AMD eat diets rich in green leafy vegetables, whole fruits, any type of nuts and omega 3 fatty acids. Many of these foods have anti-oxidant properties that help to “turn off” genes involved with inflammation, an important factor of retinal diseases. Salmon, mackerel and sardines have the highest levels of omega-3 fatty acids. An analysis that combined the data from 9 different studies showed that fish intake at least twice a week was associated with reduced risk of early and late AMD. Other studies show that Omega-3 fatty acids improve mitochondrial function, decreases production of reactive oxygen species (free radicals that damage cells) and leads to less fat accumulation in the body. The green leafy vegetables contain important protective macular pigments (carotenoids) called lutein and zeaxanthin that reduce the risk of AMD by 43%. High levels of lipid or fat deposits in the body (obesity) can “soak-up” the lutein and zeaxanthin so that they are not available to protect the retina.

The goal is to increase the omega-3 fatty acid and carotenoid levels to protect the eye. Below is a list of foods that are eye healthy:

Foods that have lutein or zeaxanthin:

– 6mg/d of lutein and zeaxanthin – decreased

– Lutein/zeaxanthin content – ug/100g wet weight

– Kale, cooked – 15,798

– Spinach, raw – 11,935

– Spinach, cooked – 7,053

– Lettuce, raw – 2,635

– Broccoli, cooked – 2,226

– Green peas, cooked – 1350

Women’s Eye Health

With this being Women’s History Month, we thought it appropriate to discuss women’s eye heath. Your vision is one of the most important things in your life. Vision loss can make everyday tasks more difficult, impede your work and lead to depression.
women's eye health
According to Prevent Blindness America (PBA), 66% of people who are blind or visually impaired are women. This is primarily due to the fact that women have more risk factors for vision loss than men. Sadly the same study also revealed that only 9% of women realize this. Early intervention can help prevent blindness in many cases. Many blinding eye diseases can be treated to prevent blindness and almost all eye injuries can be prevented.

Here is a closer look at why women are affected more than men, and what condition they need to be aware of for early diagnosis and sight-saving treatments.

Why Women Lose Vision

  • They live longer than men and many eye diseases are age-related. Examples are cataracts, macular degeneration and diabetic retinopathy. The rates of these diseases are increasing as the baby boomer population ages.
  •  

  • Some eye diseases are intrinsically more prevalent among women, like dry eye syndrome which is believed to be linked to hormones. It is 2-3 times more likely in women than men. Hormonal changes can influence vision changes across the life span of a woman, from pregnancy to post-menopause.
  •  

  • Women have higher rates of autoimmune diseases such as lupus, rheumatoid arthritis and multiple sclerosis. The serious side effects of these conditions can affect your eyes, causing vision loss.
  •  

  • Social and economic factors can access to health care for women restricting early detection and treatment which could prevent or limit vision loss.
  •  

  • While behavioral and environmental factors are not restricted to women, poor nutrition and obesity can cause diabetes and subsequent diabetic retinopathy; while smoking is also a proven risk factor for eye diseases such as cataracts and macular degeneration. Women under 23 are the fastest growing segment of new smokers.

Eye Conditions More Prevalent in Women

  • Cataracts are the world’s leading cause of blindness. They are the result of a clouding of your eye’s normally clear lens. They can be treated with cataract surgery, where the cloudy lens is replaced with a clear synthetic lens.
  •  

  • Glaucoma is the second-leading cause of blindness in the Us. It is called the silent thief of sight because there is no warning. It happens when pressure in the eye — intraocular pressure or IOP — is too high, damaging the optic nerve which sends vision signals to the brain. Open-angle glaucoma, the most common type, affects men and women equally. But women are 2-4 times more likely than men to get closed-angle glaucoma. One of the possible reasons for this is that the front chamber between the iris and cornea is shallower in women than men and can block fluids from draining out of the eye, thus increasing pressure. Glaucoma is also genetic, meaning you are at higher risk if someone in your family has had glaucoma. When caught early, there are treatments that can help control your IOP. If it is not controlled early, blindness can result and it is irreversible.
  •  

  • Age-related macular degeneration (AMD) is the number one cause of vision loss in people over 40 in the US. One of the reasons women are at higher risk is because they tend to live 5-7 years longer than men. AMD gradually destroys the central part of your sight that helps you read or drive. There are two types of AMD. Dry AMD, which occurs when drusen accumulate under the retina. There is no treatment for dry, yet accounts for 90% of the cases. Wet AMD occurs when new blood vessels grow and leak between the retina and eye’s outer layer. There is a treatment of anti-VEGF injections for this version of AMD. The earlier the disease is diagnosed and treated, the better the results. Like glaucoma, it is an inherited eye disease.
  •  

  • Diabetic retinopathy is a result of diabetes. When blood sugar levels are too high, the vessels that feed the retina weaken and eventually leak, which cause the macula to swell. In its most dangerous form the retina may detach from the back of the eye leading to blindness. Diabetes is also hereditary, but controllable with early diagnosis and treatment.
  •  

  • Dry eye syndrome occurs when your eyes produce too few tears. Your eyes may burn, sting or feel gritty, making your vision blurry or you may blink more. Contrary to the name, you may appear weepy as the dryness may stimulates more tear production. Thanks to hormones, women are more susceptible. In postmenopausal women, the shift in balance between estrogen and progesterone can be responsible.
  •  

  • Pregnancy-related eye changes, like menopause, are caused by hormone shifts and can cause several temporary eye conditions, such as dry eye and corneal swelling.

Pink Eye Tips and Prevention

pink eye
Pink eye is an inflammation or infection of the thin, clear covering of the white of your eyeball (the conjunctiva) and the inside of your eyelids. When the small blood vessels in the conjunctiva become inflamed they are more visible making the whites of your eye to appear pink. Also called conjunctivitis, it can affect one or both eyes.

Common symptoms of pink eye include:

  • Redness in the white of the eyeball(s) and or inner eye lid(s)
  • Increased tearing or discharge
  • Slightly blurred vision from discharge
  • Crusting of the eyelashes from the discharge that may prevent eyes from opening after sleep
  • Mild eyelid swelling
  • Itching or burning sensation
  • Increased sensitivity to light
  • Irritation or gritty feeling in your eye(s)

Make an appointment with your eye doctor if you notice and of the symptoms of pink eye. Some forms are highly contagious for as long as two weeks, so an early diagnosis could protect those around you from contacting the disease. If you were contact lenses, stop using them until directed by your doctor.

There are four general types of pink eye.

Allergic Conjunctivitis
This form is caused by eye irritants such as pollen, dust, animal dander and other environmental factors. It is not contagious. Treatment often includes applying a cool compress to your eyes and using allergy eye drops and artificial tears. In severe cases non-steroidal and anti-inflammatory medications may be prescribed.

Bacterial Conjunctivitis
This type is most often caused by staphylococcal or streptococcal bacteria, is highly contagious and can cause serious damage to the eye if left untreated. This is treated with antibiotic eye drops or ointments to speed up the healing process that can take one to two weeks. While you may see improvement after three to four days, the entire course of treatment needs to be used to prevent a recurrence.

Because this is so highly contagious here are a few things to remember so you don’t spread it to others or re-infect yourself:

  • Don’t touch your eye with your hands
  • Wash your hands frequently and thoroughly
  • Change towels and washcloths daily – and don’t share them
  • Change pillowcases often
  • Get rid of all eye cosmetics and personal care items such as eye creams – and don’t share them
  • Avoid swimming
  • Don’t reuse tissues when wiping your eyes, and throw them out immediately
  • Follow your eye doctor’s instructions related to your contact lens usage and care

Viral Conjunctivitis
This is the same type of virus associated with the common cold. Antibiotics will not work on a viral infection. Like a cold, the infection just needs to run its course which could take anywhere from a few days up to 2-3 weeks. It is also contagious like a cold, so follow the same instructions as listed above to not spread the infection.

Chemical Conjunctivitis
This can be caused by irritants like air pollutions, chorine in swimming pools or exposure to noxious chemicals. To treat this type of pink eye requires a doctor to carefully flush your eyes with saline and may require topical steroids. Acute chemical injuries are very serious and need prompt medical attention to avoid corneal scarring, intraocular damage, vision loss or the loss of an eye.

Of course the best way to deal with pink eye is not to get it. Here are some ways to protect yourself and others.

4 Super Greens for Better Sight

A healthy diet not only helps your heart, but also your eyes. Your diet should include lots of fruits and vegetables to provide you with a natural source of nutrients to help protect your sight. As wonderful as supplements are, eating the actual foods is always better. Some of the best vegetables for you are the dark, leafy greens that are rich in valuable vitamins and nutrients. These are the super greens for better sight.

With the US experiencing bitter, freezing temperatures on the East Coast, while the West Coast is having summer in February, with record-breaking hot temperatures, I thought it would be interesting to see how you could enjoy those super greens, no matter what the temperature is outside. Below is a quick look at four dark leafy greens that are a great addition to a healthy diet, watercress, arugula, spinach and kale. For each vegetable I have included a recipe that is served hot, along with one that is served cold.

Here is what you need to know about super greens for better sight.
super greens
WATERCRESS

Watercress is a cruciferous plant and part of the brassica family, like arugula and kale. It contains vitamins A, B6, B12, C, K, iron, magnesium, calcium, phosphorus, lutein and zeaxanthin. In fact, weight for weight, watercress contains more vitamin C than an orange, more calcium than milk, more iron than spinach and more folate than bananas. Watercress has the highest amount of nutrients for the smallest amount of calories.

The health benefits of watercress include boosting immunity, cancer & diabetes prevention, reducing cognitive decline, thyroid support, better cardiovascular health and stronger bones. As for your eyesight, it can help prevent or slow the onset of age-related macular degeneration and possibly cataracts.

Watercress is most commonly enjoyed fresh in salads, but can also be use in pastas, casseroles, soups and sauces. Choose watercress with deep green, crisp leaves, with no signs of wilting. Trim the stems, rinse the greens in cold water and dry. It is best if used immediately, but can be store for up to four days in the refrigerator.

ARUGULA

Arugula is also known as a salad or garden rocket. It is a small low growing herb that is packed with vitamins, minerals and antioxidants. It is rich in folates, vitamin A, B-complex, C and K and has copper, iron, calcium, potassium, manganese and phosphorus.

The health benefits of arugula include a lowered risk of cancer, healthy bones, strengthened brain function, improved mineral absorption and it boosts the immune system. Because of being a source of carotenoids, it also helps to slow the progression of age-related macular degeneration.

Arugula is popular in salads, used with milder greens to add a peppery flavor. But it can also be used in pastas, casseroles, pizzas, soups and sauces. Choose arugula that is crisp with green young leaves. Avoid the flowered harvest as those leaves are tough and have a bitter taste. Wash leaves in a bowl of water, swishing thoroughly to get rid of all sand and soil. Drain and pat dry before storing in the vegetable bin of your refrigerator for no more than a few days.

SPINACH

Spinach is a very popular leafy green vegetable, with two common varieties cultivated for food; the savory-type with dark green crinkled leaves and the flat-leaf type with smooth surfaced leaves. Spinach contains vitamin A, B-complex, C and K, along with lutein, zeaxanthin beta-carotene, potassium manganese, magnesium, copper and zinc.

The nutrients in spinach help improve blood glucose control in diabetes, lower the risk of certain cancers, reduce blood pressure, increase bone health and help iron deficiency. The lutein, zeaxanthin and beta-carotene help to potentially prevent and slow the progression of age-related macular degeneration. Lutein also works to protect the eye from free radical damage by helping filter out damaging blue and ultraviolet light.

Spinach is a universally popular vegetable, used around the world in a variety of ways, including salads, soups, noodles, pies, casseroles, dips, sauces, etc. Look for leaves that are dark green in color, crisp and not dull or yellow and spotted. Wash thoroughly to remove sand and soil, dry, trim away tough stems and store in the refrigerator for up to a week.

KALE

Kale is a member of the mustard and cabbage families and has more nutrients than spinach. Less than ½ cup has 333% of the recommended daily allowance (RDA) of vitamin A, 587% RDA of vitamin K and 200% RDA of vitamin C. This frilly-leafed vegetable also has vitamin B-complex, lutein, zeaxanthin, beta-carotene, copper, calcium, sodium, potassium, iron, manganese, and phosphorus.

The health benefits of kale include healthy muscles and skin, improved blood glucose control, lower colon and prostate cancer risk, better cardiovascular health, stronger bone health, reduced neuronal brain damage and support for red blood cell formation. The advantage for your eyes comes from the lutein, zeaxanthin, beta-carotene and vitamin A, all which work to support a healthy retina. They help protect against blue and ultraviolet light as well as the early onset and progression of age-related macular degeneration. Because of the positive impact on diabetes it also reduces the onset and progression of diabetic retinopathy.

Kale is very versatile and can be served in a variety of ways including salads, soups and casseroles. It can also be braised, broiled, sautéed and even made into kale chips by tossing them in extra-virgin olive oil and sprinkled with your choice of cumin, curry powder, chili powder, red pepper flakes or garlic powder and baking at 275 degrees for 15-30 minutes depending on how crisp you want them to be. When shopping for kale look for leaves that are crispy and crunchy with a brilliant dark blue-green color. Wash thoroughly to remove soil and sand, dry well, and remove all tough stems. It is extremely perishable, so use it as quickly as possible.

All of these dark green leafy vegetables are not only healthy for you, but can be used in many ways to make it easy to incorporate them into your diet. Here are a few ideas:

  • Throw a small handful into your blender when making your favorite smoothie
  • Add them to your next omelet or egg scramble
  • Use them for making pesto or adding to pasta sauce
  • Sauté with a small amount of extra-virgin olive and season with freshly ground black pepper and freshly grated Parmesan cheese to serve at a topping for your baked potato
  • Add it to your wrap, sandwich or flatbread

Understanding Your Eyeglass Prescription

If you need eyeglasses it is because you were diagnosed with a refractive error during your eye exam. This means your eyes have trouble focusing and images can appear blurry. Types of refractive errors include being near-sighted (myopia), far-sighted (presbyopia) or having an astigmatism (your cornea is an irregular shape).
Understanding Your Eyeglass Prescription

Understanding What 20/20 Vision Means

The number is based on you standing a distance of 20 feet (considered to be the norm) in front of a Snellen or Tumbling E eye chart to test your visual acuity. If during an eye test you can read the big E at the top of the eye chart, but none of the letters below that, your vision is considered 20/200. That means you can read a letter at 20 feet that people with “normal” vision can read at 200 feet, meaning you have very poor visual acuity. If you can read the fourth line from the bottom of most charts, you vision is 20/20. Any line below that would be 20/15 or below and indicates that you have exceptional visual acuity. Each eye is tested separately as your eyes are designed to compensate for each other and would not give an accurate reading.

Understanding Your Eyeglass Prescription

The prescription you receive may be a chart with headings that are filled in, or it may just be written out. In any case, it is written in a specific order, with the results for each eye listed first.

  • OD is an abbreviation for oculus dexter, meaning right eye, while OS is oculus sinister, meaning left eye. If both eyes are being referred to the abbreviation you will see is OU (oculus uterque) meaning both eyes.
  • The next term on your prescription is Sphere (SPH) and is are measured in diopters (D). This number tells you how strong your lenses need to be to correct your vision. If this number has a minus sign (–), you are nearsighted; if the number has a plus sign (+) or is not preceded by any sign, you are farsighted.
  • Next may be cylinder (CYL), an indicator of the lens power if you have an astigmatism. The number for the CYL has the same format as the SPH, a minus sign (for the correction of nearsighted astigmatism) or a plus sign (for the correction of farsighted astigmatism). If there is no number given you either have no astigmatism, or your astigmatism is so slight that it is not really necessary to correct it.
  • If you do have a CYL number you will also have an axis number, based on a protractor scale that tells you where on the eye the astigmatism is found. For example, SPH –2.50 D CYL +5.00 Axis 40 means you have a nearsightedness of -2.50 dioptics with an astigmatism of +5.00 along the 40 degree axis.
  • If you are getting bifocals or progressive lenses, there is another number called an “Add.” This number is the amount of additional correction your eyes need to focus at close distance and will always be a positive number, whether or not the + sign is there.

Needless to say, eyeglasses are expensive, but understanding a prescription should help you understand why. The stronger the lens the more expensive it is and then with each adjustment, the cost also increases. Also don’t forget that anti-glare or UV protective coatings add to the costs, but may be well worth it. Eye glasses are an investment in your safety, job, independence and letting you enjoy any leisure-time activities you enjoy.

Layers of the Retina

The retina at the back of the eye is essential for all vision. Each layer of cells in this tissue serves a specific purpose. As we prepare for Age-Related Macular Degeneration Awareness Month in February, a closer look at the layers of the retina and their function.

layers of the retina

Layers of the Retina

Choroid – This is made up of a layer of blood vessels that supply oxygen and nutrients to the retina. Defect in the CHM gene can cause choroideremia, leaky blood vessels can expand in the retina causing wet age-related macular degeneration (AMD) and diabetic retinopathy.

Retinal pigment epithelium – This is a single layer of cells that provide essential nutrition and waste removal for the photoreceptor cells. Accumulation of waste can lead to AMD and Stargardt disease.

Photorecptors – This is where the rods and cones are located that convert light into electrical signals. Rods help you with night and peripheral vision. Cones are more concentrated in the macula (the central part of the retina) and proved central and color vision. Death of the rods can cause vision loss called retinitis pigmentosa, while AMD is the loss of central vision.

Horizontal cells – These cells are connect to the photoreceptors that surround the bipolar connected photoreceptor cells and help the help integrate and regulate the input from multiple photoreceptor cells, increasing your visual acuity.

Bipolar cells – The dependence of each layer of the retina on each other is exemplified here. These cells take the electrical information from the photoreceptor cells and pass it along to other retinal cells.

Ganglion cells – These cells extend to form an optic nerve that conveys information to the brain and take the electrical information from the bipolar cells and process it to determine shapes, contrast and color. Glaucoma vision loss results from high intraocular pressure that affects the optic nerve, interrupting the signals to the brain.

Wearing Contact Lenses in Winter

Wearing Contact Lenses in Winter This has been a cold winter so far, and since it is only January, it is bound to get colder. The extreme cold, combined with winds, snow, rain and other environmental factors, can really take a toll on your eyes. And while it may be snowing or raining, winter air is actually drier than any other season. This can be especially difficult if you wear contact lenses. Here is what you should know about wearing contact lenses in winter.

  • Wear sunglasses for protection from UV rays and wind. Your eyes can become sunburned which cause blurry vision and can make your eyes feel like they are burning (think of your sunburned skin feels) for 24 to 72 hours. It will also protect your eyes from snow, rain or anything else the wind can send your way.
  • Avoid direct sources of heat such as heating vents and fireplaces. Indoor heating can draw the moisture out of the air, so consider a humidifier to help maintain the correct amount of moisture in the air to help keep eyes moist. Cool-air humidifiers have less of a tendency toward mold and bacteria.
  • Speaking of hydration, we also tend to drink less water in the winter months, so make a concentrated effort to keep up your water intake.
  • If it is so dry, why are my eyes watering? This is a common question and the answer may be a bit counter-intuitive. Anything that irritates your eyes, including dryness, causes a tearing reflex. Your tear glands go into overdrive trying to replace the moisture to your cornea. To try and reduce the tearing, you can use eye drops or artificial tears specifically designed for use with contact lenses.
  • Your eyes are not the only thing that dries out in the winter, so does your skin. Try to put in your contacts before moisturizing your skin, especially your hands. So wash your hands, put in your lenses and then use your creams and lotions.
  • Change out your contact lenses regularly in cold weather according to the recommended schedule, be it daily, every two weeks or monthly. This will allow them to better conduct oxygen, reduce irritation and increase comfort.
  • Take a break from your contacts and wear your eyeglasses. Putting them on when you get home from work can make a big difference. Contact lenses dry your eyes out on their own, when you add cold weather it gets that much worse.
  • Get plenty of sleep, which also helps with the dryness and fatigue. This will help you start the day with your eye refreshed and ready for the many things you will put them through throughout the day ahead.

Do you have any other suggestions that have helped you cope when wearing contact lenses in winter?

Silent Thief of Sight – Glaucoma

January is National Glaucoma Awareness Month. The National Eye Institute, through their education program NEHEP, have created this infographic to provide you with information you need to know about this blinding eye disease.

When adults reach their 40s, they often begin to notice small changes in their vision that can affect their daily lives and jobs. It could be difficulty in reading a book or working on a computer. This can be annoying, but it can often be addressed by seeing an eye care professional for comprehensive dilated eye exam. This allows the doctor to detect diseases and conditions that can cause vision loss and blindness and yet have no symptoms in their early stages.

Silent Thief of Sight – Glaucoma

Glaucoma is one of these age-related eye diseases that has no early symptoms, which is why it is called the silent thief of sight. It is actually a group of diseases that can damage the eye’s optic nerve and result in vision loss and blindness. Open-angle glaucoma is the most common form disease.

In addition to an eye exam, you can reduce your chances of losing your vision to glaucoma by also:

  1. Live a healthy lifestyle that includes maintaining a proper weight, eating healthy foods, and not smoking.
  2. Know your family history to determine if you are at a higher risk for some eye diseases.
  3. Protect your eyes against harmful UV rays from the sun or your computer by wearing sunglasses when you are outdoors or computer glasses when using the computer for extended periods of time.

9 Tips To Relieve Digital Eye Strain

Online shopping has continued to grow this year, which means more people are spending more time on computers, tablets and phones. While the convenience of online shopping can’t be beat, it could be costing us sleep, giving us headaches, making our vision blurry…and even affecting our posture.

Digital Eye Strain

Digital eye strain (DES), also known as computer vision syndrome (CVS), is a consequence of spending two or more hours at a time looking at a digital screen. Nearly 30% of adults spend more than 9 hours each day using digital devices, while 25% of children use digital devices more than 3 hours a day.

This can result in dry or itchy eyes, blurred vision, eye twitches, headaches and even back and neck pain. Using digital devices for an extended period of time increases your tendency to lean into the device, as you try to focus or compensate for glare from reflected light (room lighting or windows). Holding these positions for long periods of time are what create the back and neck pain.

As for the many eye symptoms, they can come from

  • poor lighting
  • improper viewing distance from device
  • not blinking often enough
  • poor screen contrast
  • glare on the screen
  • UV blue light

To help you deal with DES, here are 9 tips to relieve digital eye strain.
