The macular degeneration can cause different symptoms in each person. Sometimes only one eye lose the central vision while the other see very well during many years. If both eyes are affected, is very difficult to read or work.
The Macular Degeneration is a degenerative alteration of the central part of the retina known as macula, that is responsible for the central vision. This part of the retina allows to read, watch the television or recognize the faces of the persons.
In some cases, the macular degeneration related to the age advances very slow that the persons do not notice any change in their vision. In other cases, the illness advances very fast and can cause the lost of the vision in both eyes. The macular degeneration is one of the principal causes of the lost of the vision in the north American people older than 60 years.

· Familiar History: The persons with relatives who have had macular degeneration have more risk to develop the illness.
· Sex. The women seem to have a greater risk than the men.
The macular degeneration related to the age is detected making a complete exam of the eyes which includes:
Proof of visual sharpness In this proof is used an optometric board to measure your sight at different distances
Exam with dilatation of the pupilas : To dilate or widen the pupilas, the ophthalmologist put some drops on the eyes. The ophthalmologist see trough special magnification lens to examine the retina and the optical nerve to see if there are signs of macular degeneration or other problems of the eyes. After the exam, your near vision will be blurred during several hours
Tonometry An instrument to measure the pressure inside the eye is used. For this proof, the ophthalmologist can put some drops to numb your eyes.
