Cytomegalovirus Retinitis

Cytomegalovirus Retinitis is a threatening of sight disease often associated with AIDS. In the earlier period, about one-fourth of active Acquired Immunodeficiency Syndrome patients developed Cytomegalovirus retinitis. However, this number is dropping radically. This is due to an effective combination of drugs employed to treat AIDS. This combination of drugs helps AIDS patients in restore function of their immune system. In last few years, these combinations of drugs have aided in decrease the presence of CMV Retinitis in AIDS by 80 percent. 

Cytomegalovirus (CMV) Retinitis Signs and Symptoms:

When CMV attacks the retina, it starts compromising the light-responsive receptors, which enables us to see. It does not result in pain; however, you may see small specks or eye floaters and experience decreased peripheral vision or blurry vision. Sudden vision loss and light flashes also can take place. This disease normally begins in one eye but frequently involves both the eyes.

If this disease is left untreated, Cytomegalovirus Retinitis can cause blindness and a detached retina in few months. AIDS patients on some occasions also experience change in optic nerve and retina without the symptoms of CMV retinitis.

Causes of Cytomegalovirus (CMV) Retinitis:

CMV retinitis occurs by the Cytomegalovirus, a very common type of virus. Cytomegalovirus (CMV) belongs to the family of viruses known as herpes family. Around 80 % of peoples harbor anti-bodies to Cytomegalovirus, which shows that they are virus infected but their bodies have effectively fought it off.

For the AIDS patients, the only difference is that their non-functioning or weakened immune system cannot fight this virus. Other individuals with a suppressed or weakened immune system like those undergone a bone-marrow transplant or chemotherapy are also at a risk. Cytomegalovirus Retinitis takes place less frequently in these individuals than in individuals suffering from AIDS.

Usually the retina is tidily stratified. One gets an infection in external most part of the retina, with CMV retinitis. It is also known, that the virus is dormant on the outer most layer of the retina earlier to the development of Cytomegalovirus retinitis. However, the virus once activated starts to cause cell death spreading into the deep layers.

Treatment of Cytomegalovirus (CMV) Retinitis:

If an individual have AIDS and is experiencing visual signs and symptoms, he should look for a retina specialist without wasting a single day. A person diagnosed with Cytomegalovirus Retinitis should visit the consultant every month. After the disease gets controlled, one may visit the eye specialist in every four to six months.

CMV Retinitis Drugs: The antiviral drugs usually used for the treatment of CMV retinitis are Cidofovir, Foscarnet and Ganciclovir. These drugs can slow the growth of CMV. However, these drugs cannot cure it clearly. Like many other medications, these treatments have serious or unpleasant side effects.

Nowadays, ganciclovir is offered in a pill form. It is also controlled in an implant called Vitrasert. This implant is put inside the eye. Throughout the period of five to eight months, Vitrasert gradually releases a specific amount of ganciclovir. The medication goes straightly into the retina and vitreous, to the Cytomegalovirus (CMV) Retinitis.
