What causes the loss of central vision?

There are several known causes attributed to the loss of central vision, including cataract, macular degeneration and holes, as well as complications from other conditions such as multiple sclerosis. In some cases, a centrally located loss of vision may be the result of brain tumors or aneurysm. This type of vision loss is characterized by changes or loss of vision in the center range of normal vision and can affect one or both eyes depending on the cause discovered. The treatment used to remedy the problem varies greatly and is determined according to the most effective treatment available for loss of vision. In many cases, this form of eye failure may be repaired and perverted. Cataracts are a cloudy film that develops over the eye lens and prohibits the light to reach retina and seriously prevents normal vision. This eye disease is most common in the ancient patients and the symptoms usually deteriorate. This can lead to blurred central vision and even complete blindness if it is not treated. DoctorŘI can usually remove cataracts, effectively treat the loss of central vision and restore normal vision.

Another common cause of central vision loss is macular degeneration, eye disease that often affects older patients. Macular holes are similar to degeneration and both macula eyes and retina are adversely affected. Because this disorder affects the capabilities of central vision, many patients with macular degeneration have difficulty performing normal daily tasks such as driving and reading. In some patients, visual changes are so gradual that the patient may not notice changes and in others the loss of vision is quick. Laser treatment can help slow down the disease progression for some patients.

Some patients with multiple sclerosis may also develop central vision. This occurs when the patient downloads optical neuritis, a condition that simply odkaIt turns on the swelling of the optical nerve. Functional optical nerve is necessary to obtain visual messages into the brain, so this disorder seriously limits the function of human vision. Optical neuritis can affect one or both eyes and can either manifest itself as a gradual loss of vision for several days, or may occur almost immediately. Treatments such as anti -inflammatory drugs are used to try to reduce or remove nerve swelling.

Central vision loss occurred in cases of brain trauma, such as tumors or in the case of aneurysm. Doctors can perform a number of tests to see if the loss of vision is the result of this type of brain damage. During the initial onset of vision loss, doctors are most likely to be more interested in checking the aneurysm or tumor than vision correction, and the eyes usually return to normal without intervention.
