These two words and that is something for the rebuilding or something. I recently introduced, for example, when a person has an eye infection and the infection later, having climbed the immune system. What is the appeal?

In people whose immune system is CMV by the natural defenses of the body controlled. However, in people with weakened immune systems - the life of immunosuppressive therapy for cancer or organ transplantation, or with advanced HIV / AIDSthe virus can cause infections in the body. The weakened immune system can prevent the virus in check, allowing you to attack all areas of the body.
Understanding of the immune system
Retinitis - The retina is the nerve sensitive to the back of the eye, the pictures of you in electrical impulses that are interpreted by the brain to see the light. Without healthy retina is visually impaired. Retinitis term refers to an inflammation or swelling of the retina caused by a variety of things, but mostly the result of an infection. Inflammation of the retina greatly impair vision.
CMV retinitis - If the two words together you get CMV retinitis, an inflammation of the retina caused by cytomegalovirus infection.

Last medications through the hole surgical implants have to organize themselves more effectively. These implants have a high concentration of antiviral drugs directly to the infected area. Although these drugs are availablE, carry their own side effects and may prove less effective in severely immunocompromised patients. In addition to the procurement of antiviral drugs and for its treatment of CMV, the most important step is to implant drugs for the treatment of HIV and to improve the immune system to obtain.
