Foods that Improve your Eyesight

July 30, 2017

SheKnows.com quotes family and preventative medicine expert Dr. Mikhail “Mike” Varshavski and optometry specialist and licensed acupuncturist Dr. Marc Grossman on diet. In terms of what you can (and should!) be adding to your diet, both Varshavski and Grossman had similar recommendations.

1. Omega-3 fatty acids

These essential fatty acids can help prevent AMD and even help drain fluid from your eyes that can lead to high eye pressure and glaucoma. You can get sufficient servings through:

  • Fish oil pills
  • Salmon or tuna
  • Dark green leafy vegetables
  • Flax seeds or flaxseed oil
  • Walnuts

2. Vitamin A

According to Grossman, “Vitamin A as an antioxidant plays an important role in immune function, helping the surface of the eye to be an effective barrier to bacteria and viruses. It may help or slow the progression of dry macular degeneration.” Try adding:

  • Carrots
  • Cantaloupe
  • Sweet potatoes
  • Kale or spinach
  • Dairy products

3. Vitamin C

“Vitamin C helps the body form connective tissue like collagen, which is found in the cornea of the eye,” Grossman told SheKnows.  “Studies are showing that vitamin C may help prevent the formation of cataracts and vision loss from macular degeneration.” Incorporate these easy additions into your daily meals:

  • Citrus fruits (e.g., oranges, grapefruits)
  • Red, yellow and orange bell peppers
  • Kale
  • Brussels Sprouts
  • Strawberries, raspberries or blueberries

4. Non-processed complex carbohydrates

Eating a high-glycemic diet results in blood sugar spikes that can cause eye damage and increase your chances of developing diabetes and AMD. Complex carbs break down more slowly, providing your body with more fiber, sustained energy and a more controlled rise in blood sugar.

  • Quinoa
  • Brown rice
  • Whole grain pasta, breads, and cereals
  • Kidney or Black beans
  • Lentils

Overall, maintaining a balanced diet will do wonders for your vision. “Recent evidence shows that a high-fat diet wreaks havoc on your vision as it forms harmful fatty deposits into the retina and occludes the tiny blood vessels leading to the eye,” Varshavski told SheKnows. “In general, if you want to take care of your vision, you need to take care of your health in its entirety.”

Treatments for dry Macular Degeneration

July 22, 2017

There are drugs in development for dry macular degeneration. They will take a few years until they are approved by the FDA. In the meantime, what can be done?

In an article in belmarrahealth.com, there are several recommendations.

Treating dry macular degeneration

The unfortunate reality of dry macular degeneration is that it cannot be reversed. Symptoms develop gradually over time, with the user not realizing that they have vision problems until much later in the course of the condition. If caught early, treatment can be initiated before significant levels of vision loss occur. The following are some of the most common treatment methodologies.

  • Vitamin intake: Certain vitamins are known for improving symptoms of dry macular degeneration. In some cases, they help to slow down progression as well. Zinc supplementation helps in this regard. Vitamins rich in anti-oxidants such as A, C, and E are also beneficial.
  • Beta-carotene: A commonly promoted attribute of carrots, beta-carotene can also be useful for promoting eye health. However, beta-carotene supplementation is thought to increase the risk of lung cancer in smokers while increasing the risk of coronary artery disease.
  • Healthy lifestyle: Eating a well-balanced diet that includes fruits and vegetables can help not only promote overall health but also maintain your vision.
  • Surgery: Selected individuals with significant vision impairment in both eyes may require this form of treatment. Surgically implanting a telescopic lens into the eye can help magnify field of vision. This surgery can help improve both distance and close-up vision but has a very narrow field of view.

Home remedies for dry macular degeneration

Your lifestyle can play an important role in the progression of dry macular degeneration. By making simple changes to your daily routine, you can give yourself the best chances for slowing down vision loss. Most of the home remedies recommended act as preventative measures to help you keep your sight as long as possible.

Don’t smoke: Smoking is considered a risk factor for dry macular degeneration development, so by quitting the habit, you’re helping preserve your vision further. If quitting smoking is too difficult, speak with your doctor to get some help.

Choose a healthy diet: Foods that contain antioxidants help to prevent damage to the sensitive structures in the eye. Several fruits and vegetables help to protect eye health. Some of these foods include kale, spinach, broccoli, and peas. These foods contain lutein and zeaxanthin—types of antioxidants that may benefit people with macular degeneration.

Foods with high zinc content may also help preserve vision. These include high protein foods such as beef, pork, and lamb. Non-meat sources include milk, cheese, yogurt, whole grain cereals, and whole wheat bread.

Studies have shown that food with omega-3 fatty acids such as salmon, tuna, and walnuts may lower the risk of advanced macular degeneration. However, this correlation was not seen when taking omega-3 supplements.

Manage other medical conditions: Having high blood pressure or cardiovascular disease can accelerate the progression of macular degeneration if not properly managed. It is recommended to control these conditions with prescribed medications to help slow down macular degeneration progression.

Exercise regularly: Getting exercise on a regular basis helps to slow down macular degeneration and keep the body healthy. Losing excess pounds also helps.

Get routine eye exams: There is no better way to determine if something is wrong with your vision then to test them, and the most qualified person to assess your eyes would be an eye doctor or ophthalmologist. By going to your eye doctor on a regular basis, you can be sure that if macular degeneration were to begin, you would catch it at the earliest stage possible.

Vitamin supplementation: Patients with intermediate or advanced macular degeneration taking a high-dose formulation of antioxidants can help reduce the risk of vision loss. Unfortunately, those in early stages of the condition do not benefit from these supplements. The following vitamins and dosages are recommended:

  • Vitamin C – 500mg
  • Vitamin E – 400IU (international units)
  • Lutein – 10 mg
  • Zeaxanthin – 2 mg
  • Zinc (as zinc oxide) – 25 or 80 mg
  • Copper (as cupric oxide) – 2 mg

Occupational therapy eases depression in patients with age-related macular degeneration

July 18, 2017

With any type of medical condition, a loss of independence can lead to growing feelings of depression. People living with age-related macular degeneration experience a gradual erosion of their independence as failing eyesight makes simple tasks such as navigating their homes or reading medicine bottles quite di­fficult.

A study published in the journal Investigative Ophthalmology & Visual Science examined two therapeutic approaches to macular degeneration rehabilitation and how they affected patients’ levels of depression. In the study, subjects were provided with the same baseline low-vision optometry evaluation and in-office patient training, and then split into two groups. The first group received six one-hour, in-home sessions with an occupational therapist, who helped the patients work on practical lifestyle tasks such as writing checks, measuring ingredients and pouring liquids. The second group received an equal amount of time with a counselor, who engaged in supportive talk therapy about their vision loss and disability, but offered no pragmatic advice on how to complete chores or navigate their environment.

After four months, researchers assessed the progress of both groups. The patients who received the occupational therapy showed greater improvement in their ability to perform daily activities than those who did not. (The talk therapy participants did experience some improvement, likely attributed to the initial low-vision optometry sessions and possibly from the encouragement they received from the in-home counselor.) The researchers also concluded that when patients improved in their functional ability, their level of depression decreased, according to AOA.
