Macula lutea (yellow spot) is a formation close to the visual nerve at the back of the eye, is full of lumps and a part of the retina that distinguishes fine details in the center of the field of vision. In some elderly people choroid, which is located below the retina, constrict and lower the blood supply of the macula. This causes macular degeneration, and the result is blurring of direct vision. In many cases both eyes are affected, either at the same time or one at a time.
Macular degeneration usually develops gradually and never hurts. If both eyes are affected, a person cannot read or perform actions that require sharp vision. Ultimately, the direct vision disappears, but in both eyes there is always an outer visual field.
What to do?
Most cases of this disease are incurable, but if you notice the symptoms, you should immediately go to the doctor. The vision can occasionally be repaired by glasses that greatly enlarge, and sometimes laser therapy can stop this degeneration if it is discovered at a time.
