Amblyopia most commonly describes a lazy eye syndrome. However, the term also can refer to an ocular disorder known as nutritional or toxic amblyopia, a condition of the eye causing visual deterioration or blindness. It is caused by optic nerve damage, often due to poor nutrition. The lack of certain vitamins in your diet over several years can trigger this nutritional or toxic amblyopia. By restoring these vitamins to your system, you can slow the progress of amblyopia and possibly regain some visual acuity.
Vitamins
Folic acid and vitamin B-12 are key for maintaining a healthy optic nerve. Toxic amblyopia can be caused by a deficiency in either of these nutrients.
Folic acid is responsible for DNA synthesis and brain tissue maintenance. The primary functions of vitamin B-12 include fatty acid synthesis, energy production and regulation of folic acid. While you can find supplements of these vitamins at a health or grocery store, you can also add natural sources through diet. For folic acid sources, look for dark and leafy vegetables, nuts, seeds, whole wheat bread, oranges, and poultry.
Good sources of vitamin B-12 include red meat, eggs, fish, dairy, and fortified cereals and grains. Many amblyopia cases require more than a simple diet adjustment; your physician may administer regular injections of vitamin B-12. Through regular treatment with vitamins, nutritional amblyopia can be stopped and even partially reversed.
Lazy Eye
To clarify, vitamins or diet will not correct lazy eye amblyopia. The above treatment therapy is recommended only for nutritional or toxic amblyopia. A lazy eye usually requires corrective eyewear, eyedrops or even surgery.
