Nutritional Optic Neuropathy Causes & Prevention

Eye health & nutrition in San Jose, CA

It’s not every day that a news story educates the public about the strong link between nutrition and ocular health. But it happened recently with the curious case of a British teen who survived for years on a diet centered on chips and crisps — or, as we like to call them in the U.S., French fries and Pringles. He rounded out his daily menu with white bread, sliced ham and sausages.

Bay Area ophthalmologist Mark Mandel, MD, believes this is the perfect cautionary tale for parents and kids alike. After a decade on this adolescent dream diet, the teen suffered substantial damage to his nervous system, including the optic nerve. He experienced partial hearing loss and nearly total loss of sight.

How Does Nutritional Optic Neuropathy Develop?


The clarity of your vision and health of your eyes are dependent on a variety of lifestyle habits. In the case of the teen, his levels of B12, vitamin D, copper, folic acid, magnesium and selenium had collapsed. This condition, known as nutritional optic neuropathy, is more often seen in places with famine, poverty and conflict, not in countries that deep-fry, process and wrap in paper their daily sustenance.

The last reported epidemic of nutritional optic neuropathy occurred in Cuba during the early 1990s, when a disintegrating economy limited healthy diet options for the general population.

Sometimes the condition develops when intestinal problems, changes resulting from bariatric surgery or the use of certain medications interfere with the proper absorption of nutrients. It can also happen when excessive alcohol consumption crowds out balanced meals, or even in the case of individuals who follow a very strict vegan diet.

Eye Nutrition, from A to B


From an early age most of us learn from our parents, or even a cartoon rabbit, that vitamin A is vital to eye health. B vitamins, along with iron and thiamine, are also essential. Thiamine deficiency can develop quickly, and impact eye movement and the optic nerve.

Non-starchy plant foods, such as fruits and leafy vegetables, are ideal sources of vitamin B. This eye-healthy vitamin can also be found in whole grains, eggs, dairy products, meat, nuts, seeds and legumes. Because many agronomists believe that overuse of farmland has resulted in depletion of nutrients in the soil and the produce grown there, daily vitamin supplements are also a good idea.

Bay Area ophthalmologist Mark Mandel, MD, reminds patients that nutrition plays a role in other aspects of eye health as well. Lack of nutrients can lead to early onset of cataracts or macular degeneration. And a poor diet has even wider health implications, as it correlates strongly with development of diabetes, heart disease, stroke and certain cancers.

Healthy Aging Month: Tips for Eye Care Through the Years

Healthy Aging Month Eye Care Tips in San Jose

It is normal to notice changes in your vision as you get older. These may include loss of focus, having trouble distinguishing colors, and needing more time to adjust changing levels of light. Still, it is important to take precaution to minimize the risk of serious eye problems as you get older.

In honor of Healthy Aging Month, Bay Area ophthalmologist and cornea specialist Mark Mandel, MD, is here to share ways you can help preserve your vision and care for your eyes through the years.

Eat a Healthy, Eye-Friendly Diet

There is enough scientific evidence to suggest that consuming certain vitamins and minerals can minimize the risk of certain eye diseases, including cataracts and age-related macular degeneration. For good eye health, eat foods high in the following nutrients:

  • Vitamin C
  • Beta-carotene
  • Lutein
  • Zeaxanthin
  • Omega-3 fatty acids

Don’t Smoke

Smoking affects various aspects of your health, and your eyes are no exception. Research shows that smoking increases the risk of age-related macular degeneration, cataracts, glaucoma and other eye diseases.

Protect Your Eyes from the Sun

Protecting your eyes from the sun’s UV rays minimizes the risk of developing serious eye conditions, including cancer and cataracts. The best way to protect your eyes from the sun is to wear sunglasses that offer 100 percent UV protection. Because the sun’s rays can penetrate through clouds, it is essential you wear sunglasses year round, even during cold, overcast weather.

Manage Health Conditions

Health conditions such as hypertension and diabetes are linked to certain serious eye diseases, including cataracts. If you have a chronic condition, work with your primary care doctor to keep it under control. Take all medications as prescribed, see your primary doctor regularly and keep your eye doctor in the loop when it comes to your general health. You should also maintain a healthy weight, as being overweight increases the risk of diabetes and other chronic conditions connected to eye conditions.

Keep Up with All Eye Exams

Maintaining all of your regular eye exams is important, even if you are not experiencing any symptoms. This is because many eye diseases begin asymptomatic and can only be detected through an eye exam performed by an eye doctor. How often you should get your eyes examined depends on various factors, including your eye, current eye health and family history of eye diseases.

If you are experiencing any unusual eye symptoms, we encourage you to schedule a personal appointment with our ophthalmologist and cornea specialist Mark Mandel, MD. Contact Optima Eye by emailing us or calling 877-210-2020 ext. 3 today.
