The Zika Virus: What You Need To Know

The Zika virus is prompting great concern because of a disturbing connection to a neurological birth disorder and its rapid spread across the globe. Transmitted by mosquitos, the virus has been linked to a rare birth defect called microcephaly, which causes babies to have small heads and incomplete brain development. Now a new study published in the journal JAMA suggests the Zika virus may also cause eye abnormalities in newborns. Here is an ophthalmologist’s insights on the mosquito-borne virus and its potential impact on vision.

“Babies born with microcephaly often have developmental issues, as well as hearing and vision problems,” explained Sandy T. Feldman, MD, the Medical Director of Clearview Eye & Laser Medical Center in San Diego and one the nation’s top ophthalmologists. “What’s curious about the JAMA study is that more than a third of the babies tested showed signs of scarring on the optical nerve, which can cause progressive vision loss. Researchers suspect these ocular lesions were caused by the Zika virus, not the microcephaly.”

Dr. Feldman notes 10 key health points about the Zika virus:

  • There appears to be a link between the Zika virus and microcephaly, a neurological disorder that results in babies being born with abnormally small heads and severe developmental issues.
  • All infants exposed to the virus should have a retinal eye exam. Even newborns who don’t have microcephaly but whose mothers may have been exposed to the virus during pregnancy should be monitored for signs of ocular lesions.
  • There is currently no vaccine or medicine to prevent the virus or treat the infection.
  • The Zika virus has been reported in 32 countries thus far, including Latin America, South America, Mexico, the Pacific Islands and the Caribbean. Several US states have confirmed the virus in individuals who traveled to infected areas. Experts estimate as many as four million people will be infected within the next year.
  • Symptoms of the virus are typically mild, including fever, headache, rash and pink eye. An estimated 80% of those infected never know they have the disease.
  • The Zika virus is most commonly transmitted when a mosquito bites a person with an active infection, then spreads the virus by biting others.
  • The only protection against Zika is to avoid travel to areas with an active infestation. If you do travel to a country where Zika is present, the Centers for Disease Control and Prevention (CDC) advisesusing an EPA-approved repellent over sunscreen, wearing long pants and long-sleeve shirts thick enough to block a mosquito bite, and sleeping in rooms that are air-conditioned and screened.
  • The CDC is warning pregnant women to avoid travel to infected areas and to speak with their doctor about taking steps to avoid unintended pregnancies.
  • A clinical trial for a Zika virus vaccine may begin this year, but a vaccine won’t be available for another few years.
  • Health officials are implementing traditional mosquito control techniques, such as spraying pesticides and emptying standing water receptacles where mosquitoes breed. The CDC also encourages homeowners to eliminate any standing water.

“La Vie en Rose”: The Solution for Migraine Sufferers?

Light sensitivity is a well-known symptom of migraine headaches, but most people don’t realize that light can cause them as well. One surprisingly simple solution might be pastel-tinted lenses, which have been found to effectively reduce the effect of lights or patterns that trigger visual migraines or even prevent these severe headaches entirely.

“About 18 percent of women and six percent of men in the U.S. suffer from migraines. Common triggers include dehydration, stress and lack of sleep,” explains Sandy T. Feldman, an ophthalmologist and the Medical Director of Clearview Eye & Laser Medical Center in San Diego. “For other people, it’s a visual trigger related to repetition and high contrast, like black words on a white background or a blinking light on a computer screen.”

People who get migraines have a more than usually sensitive (“hyper-excitable”) brain.

As the migraine takes hold, the brain partly shuts down and becomes less active. The aura that accompanies some migraines — with symptoms such as flashing lights, blind spots and difficulty seeing — is essentially this “shutting down” process spreading across the brain. Sufferers often have to lie in a dark room for a few hours until the migraine passes.

Wearing sunglasses can help to a limited degree, and wearing colored glasses—especially those with a rosy tint—can work even better. But why? One theory is that tinted lenses redistribute the “hyper-excitement” in the visual part of the brain. A University of Michigan study found that brain activity stabilized when migraine sufferers wore tinted glasses, with about 70 percent of participants reporting significant pain relief.

“The challenge is determining which color works best for each patient. For some, pale blue might be best, and for others it’s pink. It’s a process of trial and error,” says Dr. Feldman. “The glasses are tinted light enough to be worn indoors, such as in situations where an attack may be triggered, or during a headache episode to reduce its length and severity.”

Unfortunately, precision-tinted eyewear isn’t the answer for everyone. This remedy applies to only a small portion of migraine sufferers, those with headaches primarily triggered by visual stimuli.

“There is no standard treatment for migraines, but many patients find that drinking plenty of water, eating regular meals, getting enough sleep, and not overdoing it with painkillers or caffeine can really help,” advises Dr. Feldman.

She adds, “While there’s no harm in experimenting with sunglasses, it’s important to consult your doctor to get a firm diagnosis and individual advice. There may be visual triggers you are unaware of or other lenses that might help your particular condition.”

Dr. Sandy T. Feldman Shares Diet Recommendations to Improve Your Eye Health

Did you know more than 2.7 million Americans over age 40 have glaucoma, and experts suspect half of them don’t even know it?

Glaucoma is the leading cause of preventable blindness. Since glaucoma can sneak up on you, it’s important to maintain a good diet and get regular eye exams. A poor diet can adversely affect eye health. Increased eye pressure can damage the ocular nerves, leading to partial vision loss and a susceptibility to eye disease.

Listen in as Dr. Sandy T. Feldman shares diet recommendations to improve your eye health.

Smoothies: Nutritious and Saves Your Eyes From Glaucoma

The new year brings new goals like eating healthy and keeping fit. But are you thinking about protecting some of your most important resources, such as your eyes?

How can you whittle your waistline, boost your overall health, and ward off eye disease, all at the same time? Start your day with nutrient-dense juice or smoothie, which can prevent vision-related conditions such as cataracts, macular degeneration, and glaucoma—the leading cause of preventable blindness. Currently, more than 2.7 million people in the U.S. over age 40 have glaucoma, and experts estimate that half of them don’t even know it.

“Glaucoma can sneak up on people because there are no symptoms,” said Sandy T. Feldman, MD, a San Diego-based physician who is the Medical Director of Clearview Eye & Laser Medical Center in San Diego and one the nation’s top ophthalmologists. “That’s why a good diet and regular eye exams are so important.”

While it is common knowledge that junk food packs on the pounds, it’s also possible that a poor diet can adversely affect eye pressure. When eye pressure increases to an unhealthy level, it can damage the ocular nerves; this eventually leads to a loss of peripheral vision as well as the possibility of contracting diseases such as glaucoma. Eating foods with nutrients that contribute to blood vessel and nerve health can help keep eye pressure in the normal range.

Glaucoma tends to run in families, but this is often because families share the same poor eating habits and lifestyles. People who are Hispanic or African-American are also at higher risk, as are people over 60, diabetics, and those who are severely nearsighted. In addition, chronic deficiencies in certain vitamins and minerals are thought to promote damage to the optic nerve by the increasing eye pressure.

“If you are at-risk for glaucoma, it’s important to take all precautions to prevent or reduce the progression of eye pressure,” says Dr. Feldman. “Once vision is lost it’s gone forever, but if detected in time, proper nutrition and care can prevent further loss.”

People in the at-risk group should avoid fried foods, as these are very high in oxidants that cause eye damage, along with caffeinated beverages such as coffee and soft drinks, high-protein diets, and table sugar. Instead, Dr. Feldman suggests eating more fruits and vegetables containing antioxidants and phytonutrients that protect the eyes against degeneration. Smoothies are a great way to nourish your body with produce.

One of Dr. Feldman’s favorite smoothie recipes (see below) includes blueberries and peaches, two tasty sources of antioxidants that help prevent the damage to the eyes. The recipe also contains one of the best sources of omega 3 fatty acids—flaxseeds—to help regulate the flow of fluid in the body, preventing dry eyes and normalizing eye pressure and thereby reducing the risk of glaucoma.

“Start the New Year off right by taking steps to prioritize your health,” urges Dr. Feldman.
“Jettison the junk food, experiment with eating and juicing different fruits and vegetables, and be sure to make an appointment with your eye doctor.”

Blueberry, Peach and Flaxseed Smoothie

  • 3/4 cup blueberries
  • 1 small peach, roughly chopped or ½ cup frozen peaches
  • 1/2 cup almond milk or favorite juice
  • 1/2 cup non-fat plain Greek yogurt
  • 1 tablespoon ground flaxseeds
  • 2 tablespoons honey
  • 3 ounces ice cubes (not needed if using frozen peaches)

Puree all ingredients in a blender until smooth and serve immediately. A single serving contains 220 calories, less than 3 grams of fat, and nearly 14 grams of protein.

Winter Eye-Related Health Myths Debunked

Anyone who spends any amount of time online will find an abundance of eye-related myths, misconceptions and misinformation. Dr. Sandy T. Feldman offers timely and factual information related to eye health and vision during the winter season ahead.

True or False? Dry eyes can be more troublesome in the winter.

True. Dry winter air and central heating can cause eyes to be more sensitive. An easy way to prevent dryness is by using a humidifier to add moisture to the air of indoor environments.

True or False? You don’t need to wear sunglasses in the winter.

False. Sunshine in the winter months might not seem as bright as it does in the summer, but ultraviolet (UV) light still can affect your eyes—even on cloudy days. Eyelid skin is extremely thin and allowing too much UV light through can cause a number of eye problems, including cataracts and several kinds of cancer. Skiers and snowboarders should also be aware that UV radiation is more intense at high altitudes, and sunshine that’s reflected off snow can cause a sunburn on the surface of the eye.

“We tend to protect ourselves from the sun only during the summer, but it’s something to be cautious of all year long,” Dr. Feldman advises. “Be sure to wear sunglasses that block 100% of UV light whenever you go outside, no matter what the season, and consider mirrored sunglasses or goggles if you plan to be out in the snow.”

True or False? Eyes look older in the winter.

True. Surprisingly enough, studies show that people can look as much as five years older during the winter months. Why? Circles and bags under the eyes appear significantly darker in colder months, most likely due to a lack of sunlight. Also, many of us feel more tired and lethargic in the winter due to lower levels of vitamin D, which is generated by the body only when exposed to sunlight.

Can Your Eyes Reveal Undiagnosed Health Issues?

Did you know that a routine eye exam can be extraordinarily useful for detecting significant medical issues in their earliest stages? In fact, there are a surprising number of common medical conditions that are often diagnosed first by an eye doctor, not an internist.

Most people have no idea that their eyes can reveal so much about their health. But the retina, at the back of the eye, is the only place in the body that gives doctors a close-up view of blood vessels and nerves without having to cut the body open.

“This is why it’s so important to have regular eye exams after you turn 40,” said Dr. Sandy T. Feldman. “I urge all my patients to come in for a check-up every two to four years, depending on risk factors, and more frequently after age 60. If you wear contacts, you should get an annual exam regardless of your age.”

Dr. Feldman offers several clues that might alert your eye doctor to possible underlying medical problems:

  • Eyes that bulge out could signal hyperthyroidism (an overactive thyroid gland).
  • Yellow scleras could signal a liver disease, such as hepatitis or cirrhosis (scarring of the organ).
  • A whitish ring around the cornea could signal high cholesterol.
  • Swollen or leaky blood vessels in the eyes could signal high blood pressure or diabetes.
  • Severely dry eyes could signal Sjögren’s syndrome, an autoimmune disorder in which your white blood cells attack your body’s moisture-producing glands.
  • A drooping eyelid could signal Bell’s palsy or myasthenia gravis, an autoimmune disease that causes muscle weakness.
  • Significant changes in your field of vision could signal a brain tumor or cancer.
  • Frequent bouts of inflammation of the iris in a short amount of time may signal rheumatoid arthritis (RA). About 25% of patients with RA have some type of eye issue related to the disease.

Seven Common Eye Concerns for Adults 40 and Older

It’s a fact of life for adults. Just like crow’s feet, a slower metabolism, bald spots and gray hair, age eventually affects your eyes. Some of these changes are normal, age-related developments. Others may be signs of a vision-threatening disease or condition.

“It’s important to understand how the eyes change with age and what we can do to keep our eyes as healthy as possible. The best defense for aging eyes is to be proactive,” sayid Sandy T. Feldman, an ophthalmologist and the Medical Director of Clearview Eye & Laser Medical Center in San Diego.

“We all know what to do to keep our bodies in top working order—exercise, eat right, get enough sleep, and stay out of the sun—but equal attention needs to be paid to our eyes and our vision, especially as we get older.”

Dr. Feldman offers a handy overview of common eye conditions and diseases experienced at different stages of adulthood:

1. Presbyopia: The lens inside the eye starts to lose flexibility beginning in the late 30s and early 40s, making it difficult to read up close. This condition is called presbyopia (“aging eye”) and is often easily remedied with over-the-counter reading glasses.

2. Dry eyes: Dry eyes develop with age and the use of certain medications. It is also a common problem for women during pregnancy and menopause, when hormonal changes cause changes in the eye’s tear production. People with this condition can also develop an eyelid irritation or swelling called blepharitis. In addition to seeing an ophthalmologist, there are many simple strategies to keep the eyes moist, such as using eye lubricants and taking breaks from computer screens and other electronic devices.

3. Diabetic retinopathy: Diabetic retinopathy occurs when the small blood vessels inside the retina swell, leak fluid or close off completely due to elevated blood sugar levels. Diabetics in their 50s, 60s and 70s can take steps to prevent this condition by carefully monitoring their blood sugar and blood pressure levels and seeing an eye doctor on a regular basis for screening exams.

4. Cataracts: As we age, proteins in the lens of the eye begin to clump together. These clumps—or cataracts—make the lens less transparent and cause blurry, cloudy or dim vision and increased glare. Cataracts can interfere with daily activities like driving at night and distinguishing colors. Treatment for this very common condition includes eyeglasses and surgery to remove cataracts.

5. Glaucoma: A condition that primarily affects people aged 65 and over, glaucoma damages the optic nerve, which transmits visual information to the brain. This damage often leads to loss of peripheral vision; left untreated, it can eventually cause complete blindness. Typically there are no symptoms in the early stages, so many people who have the disease are unaware of it. Another good reason to have regular eye exams!

6. Floaters and Flashes: As people grow older, the fluid that fills the inside their eye starts to shrink, forming clumps or strands. These can appear as “floaters” (small specks or lines moving in the field of vision). This fluid can also pull away from the back of the eye, causing you to see flashing lights or lightning streaks. This is normally harmless, but in some cases it can lead to retinal detachment and cause blindness. If you experience new floaters and flashes, it’s important to see an eye doctor as soon as possible.

7. Age-related macular degeneration (AMD): AMD affects the central vision, limiting a person’s ability to read and recognize faces. This can be caused by a thinning of the macula (the light-sensitive part of the retina) or by a growth of abnormal blood vessels under the retina. AMD can lead to blindness if not treated—in fact, it’s the leading cause of blindness in Americans over 65. Early and regular visits to an ophthalmologist can reduce vision loss and even recover vision.
