Age-related macular degeneration of the eye


What is macular degeneration of the eye and how is it treated?

Age-related macular degeneration is an eye disease of macular - a small part of the retina thanks to which we discern details, which allows us to read, manage the operation of the vehicle, to distinguish colours or recognize characters. When macula does not function properly, then our central vision is blurred, distorted or there is only dark spots. Macular degeneration is associated with aging and is a major cause of visual impairment and blindness in people over 50 years of age.

Macular degeneration; Symptoms

Macular degeneration can cause a lot of different symptoms, but it happens that some problems in the initial phase completely disappear or are not detected. There are times when loss of vision occurs only in one eye, while the other cannot function well for years, however, when the disease affects both eyes, we quickly register central vision loss. With this type of eye diseases there is dry and wet form. Although dry macular degeneration of the eye is a lot more common form, which is only incurred in more than 85 percent of cases, the wet form of macular degeneration is the most common cause of loss of central vision. In the case of dry forms, photoreceptors and retinal pigment cells rather slowly decay and the vision loss comes gradually, or suddenly if the disease is advanced or has taken the wet form (it is still impossible to predict whether it will happen). The wet form of the disease is characterized by the growth of new small veins under the macula that are fragile, broken easily and bleeding. The result of this process is the thickening of the macula and damage accompanied by bending the image and rapid loss of central vision. The first symptom of the dry form of macular degeneration of the eye is blurred vision and poor recognition of details and objects which are located directly in front of the eye, such as faces or letters, and emergence of small, but progressively growing black spots in the centre of the visual field. Wet macular degeneration is characterized by the fact that patients see straight lines as curved, which occurs when the accumulated liquid from cracked blood vessels begin to raise the macula. And in this case small black spots can occur.

Macular degeneration; TREATMENT

Specific treatment of macular degeneration does not exist, particularly when it comes to a dry form of the disease of the eye, then the therapy is mostly focused on the application of antioxidants, vitamins and zinc. The process can be slowed down by taking B12, vitamin B6 and folic acid, which are useful and lutein and omega-3 fatty acid. Macular degeneration of the eye in the case of the wet form of the lens can be treated by application of photodynamic therapy or laser so-called smart drugs, or anti-VEGF therapy. These drugs lead to the withdrawal of new veins in the retina of the eye, bleeding significantly reduces or stops completely, a thickening of the macula retreats. It is the leading therapy in the treatment of wet form of age-related macular degeneration. However, there is no formal therapy that fully restores lost vision, but it can certainly prevent further progression of the disease of the eye. In addition to aging, the risk factors include cigarette smoking, weaker and poorer circulation, as well as genetic predisposition. Age-related macular degeneration of the eye can also be caused by oxidative stress (effects of free radicals in the body), elevated blood cholesterol, hypertension and cardiovascular disease. Most people who suffer from this disease have deposits under the retina (comrade), which are increased, leading to further deterioration of the macula.
Macular degeneration; NUTRITION

Macular degeneration is an eye disease in which a major role in prevention has a healthy diet, which is primarily related to the consumption of healthy plant foods - fruits and vegetables, especially fresh green and leafy. It is necessary to quit smoking, to move, to maintain optimal body weight and regularly control blood pressure and cholesterol. Certain ingredients can prevent or slow the development of macular degeneration of the eye, which was confirmed by the National Eye Institute, who after great research project discovered that foods rich with vitamin C, a number of antioxidants, beta-carotene, vitamin E, and zeaxanthin lutein, as well as valuable omega-3 fatty acids and zinc greatly help.
  • Spinach – it has multiple usefulness with diseases of the eye because it contains vitamin C, beta-carotene and large amounts of lutein and zeaxanthin, which are also found in high concentrations in the tissues of the macula. Since they absorb 40-90 percent of blue light, these antioxidants in the eyes act like a sunscreen. Results of new studies confirm that eating foods rich in lutein and zeaxanthin increases the density of pigment in the macula, which ensures the protection of the retina and reduces the risks of developing the disease as the macular degeneration of the eye.
  • Carrot - beta-carotene from the vegetables is a powerful antioxidant that protects eyes from macular degeneration and cataracts.
  • Peppers, cabbage and broccoli - are rich in vitamin C, an antioxidant that also protects the eyes from damage. They can be eaten only in fresh form, and broccoli can be briefly boiled or steamed.
  • Sweet potatoes - a good source of beta-carotene and are prepared as an ordinary potato.
  • Ginkgo biloba - extract of herbs, which is a treasure trove of antioxidants, in Europe is used to treat macular degeneration.
  • Blueberries - a real mine of nutrients that protect the eyes from various diseases, such as macular degeneration and senile, including night blindness.
  • Turmeric - Scientists say this spice contributes to the preservation of sight, especially in later years, as well as degeneration that leads to blindness caused by old age.
