In retinal vein occlusion, the “blood vessels in the retina become blocked” and cause a the patient to gradually lose vision. Currently there is no treatment for the main cause of this disease, which is the “central vein that provides blood to the eye.” The disease is usually treated by using lasers to unblock the tiny blood vessels of the eye.

However, a new study done with steroids was shown effective. Patients of the study received a steroid injection every four months into the eye. After a year, “27 percent of those given a 1-milligram dose and 26 percent of those given a 4-milligram dose showed significant vision improvement.” More research is required but this initial study leaves many hopeful that this may succeed as a treatment option.

Steroids Effective In Eye Disease

A high sugar diet affects the body in many different ways, all of which put your health at risk. Widely known is the increased risk of obesity (defined by a high Body Mass Index or BMI), but an equally serious effect that is often neglected when discussing high sugary foods is the connection between excessive sugar ingestion and vision impairments. It is the intention of this article to explain how a “sugar addiction” can damage your vision severely.

There are several vision impairments that are directly caused by a high sugar diet. The most severe is age-related macular degeneration (AMD), as it is the number one cause for vision loss in United States – incidentally also the home of the most obese people in the developed world.

AMD affects the macula of the eye, which is located in the center of the retina, and controls your central vision. The fovea is located in the center of the macula where vision focus and sharpness is determined.

This disease is primarily age-related and people over 60 are at greater risk of developing the disease. The risk is about 30% in people over 75 years old and about 200,000 new cases are reported in the US each year. In its early stages, AMD displays no symptoms, but once advanced, the recipient may experience blurry vision and blind spots in the center field of vision.¹

The link between high sugar foods and macular degeneration has been confirmed by a number of studies. In the U.S, at Tufts University, a study was made based on documentation of over 4,000 adults in the ages 55-80. The study could not entirely rule out other contributing factors, but showed a strong connection between the consumption of foods that increase blood sugar levels and AMD.²

However, there are also foods that will improve eyesight and help prevent eye diseases from developing. By replacing snacks, trans fat and sugar with natural foods like fish, grains, vegetables and fruits you will not only reduce the risk of getting age-related macular degeneration, you will also prevent Glaucoma.

AMD-friendly foods:

• Whole grains
• Antioxidants
• Vegetables
• Legumes

Glaucoma-friendly foods:

• Salmon
• Broccoli
• Fish oil and liver oil
• Walnuts
• Cabbage
• Green leafy veggies

Also note that high sugar diets, or over consumption of refined sugars, may also accelerate the development of Myopia (nearsightedness). This means that, should you become nearsighted, refined sugars can exacerbate the condition quickly, thus increasing the needed optical power of your corrective eyewear. By severely decreasing your intake of sugars and refined carbs, you can decelerate the process and keep your contact lenses or glasses longer.^{3 4}

In conclusion, in order to avoid AMD, Glaucoma, and severe Myopia, you must decrease your intake of high sugar foods. Obesity and heart related diseases aside, a diet of extensive amounts of sugar can cause partial to complete vision loss.

Dump Sugar Addiction, Avoid Eye Disease

Also, when older adults score lower on tests related to memory and learning, they are more likely to have the “early stages of the eye disease age-related macular degeneration.”

Eye Disease Linked To Cognitive Impairment

Spinach and some other vegetables like sweetcorn, kale and broccoli are rich in a chemical called lutein, which, together with another carotenoid, zeaxanthin, form an oily, yellow substance at a central point of the retina known as the macula. This yellow oil, called macular pigment, is thought to protect the macula from age-related macular degeneration or AMD [snip].

This macula pigment is wholly derived from the diet, either from eating food rich in lutein and zeaxanthin, or taking such compounds as dietary supplements.

A study will be conducted in the UK to find out whether a spinach-rich diet can indeed improve vision in AMD patients. If you live in the Manchester area and have been diagnosed with the early stages of age-related macular degeneration (and have no aversion to spinach, of course), you may want to take part in the study. See the ARMD website for further details of the study on spinach and the ageing eye.
