Causes of the development of maculodystrophia

Makula translated from Latin means «spot», And the dystrophy from Greek translates as «Nutrition». From the section on the structure of the eye, we learned that the yellow spot is the central part of the retina, that is, the inner, photosensitive shell of the eye. The light, refraarting in the optical system of the eye, focuses in a yellow spot, in the so-called central jam, where millions of colums turn it into nervous signals going to the brain. The central fossa is the most sensitive place of the yellow spot, and the tomb of the central pits provide visual sharpness. It is the yellow spot and the nerves of the pits provide us with the most acute central vision, with which reading, letter, embroidery is possible, in a word, work that requires distinction of small parts.

For maculyodistrophia (it is also called sclerotic maculodystrophy) are characterized by dystrophic changes in the yellow spot, which is why nerve cells are destroyed, which perceive light. A man as a result of this gradually loses its central vision, but rather freely oriented in space, because lateral vision in the maculodystrophy is preserved.

Full blindness in this disease rarely occurs, but the maculodystrophia leads to difficulties in reading and writing, a person cannot drive a car or perform any other work that requires a full-fledged central view.

Cause of Makulodistrophia - Nervous Cell Nutrition In Yellow Stain of the Retina. This is primarily due to the sclerosis of vessels and arteriosclerotic changes, as well as circulatory disruption in retina capillaries in the field of yellow spots. That is why age-related maculodystrophy is called sclerotic. This disease is manifested in the aighty, and it is the most common cause of illusion among people over 60 years old.

One of the main causes of the disease can be called genetically determined sclerosis of vessels. If you are diagnosed «Macouture», then take care to prevent your children and grandchildren. After all, they could have inherited the features of your body, the features of the structure of the yellow stain, which increase the risk of disease.

Sometimes, of course, the maculodystrophy is found in middle-aged people, but, however, than a person older, the most likely the emergence of this disease. Statistical data say the following: at the age of 50 years only 2% of people have a chance to get maculodystrophy. This figure comes up to 30% as soon as a person will step over the age frontier of 75 years.
It should also be aware that women have a risk of maculodystrophy more than in men.

Harmful habits (in particular, smoking) and improper nutrition can cause the development of maculodistrophia. Pay attention to the statistics: smoking increases the risk of maculodistrophy trip. Also, the probability of developing this disease is more in people with high blood cholesterol.

Mechanism for the development of maculodistrophia

Due to circulatory disorder in capillaries, the retina flashes. In the final stage of the disease, the patient begins to interfere with the dark stain in front of the eye, which buys the vision of what a look. The dark spot over time becomes more in size and darker, completely obscure central eyesight.

This is because the photosensitive nerve cells in the central zone of the retina stopped working normally. Vision worsens, since new blood vessels begins behind the retina in the direction of the yellow spot. These newly formed vessels have an infallible, defective permeable wall, which is able to pass blood and intraocular liquid to the yellow stain. Nervous cells are affected, and the central vision worsens very quickly.


Important

How and why maculodystrophy developsMacouting is two types: dry and wet. If you are diagnosed with dry maculodystrophy, you must be examined by a doctor at least once a year.


Wet maculodistrophy is more dangerous. Almost all cases of irrevitable loss of vision (90%) account for this form of the disease, although it is only 10% of the total number of ill.
It is important not to postpone the laser surgery if the doctor recommends her. After laser surgery, it is necessary to regularly observe the doctor to notice the repeated flow in the walls of the vessels.
