Anti-viral drugs are used to treat the progression of the disease, but these drugs cannot completely cure it. Causes CMV retinitis is caused by a member of a group of herpes-type viruses. Prompt care and treatment is absolutely essential to control the disease and prevent blindness.

If you have been diagnosed with HIV/AIDS or have a weakened immune system and are experiencing vision changes, see an eye care professional immediately. Once the virus becomes activated, however, it will quickly trigger cell death and spread to deeper layers within the retina, ultimately leading to detachment and total vision loss. The virus may be present for an extended period, but not active on this outer layer. When stricken with CMV retinitis, the infection occurs in the most external part of your retina. Immunocompromised persons, such as those infected with HIV or otherwise immunosuppressed, develop a necrotizing retinitis that may rapidly involve the macula as well as the peripheral retina, without significant intraocular inflammation or vasculopathy (PORN). If the virus is not treated, CMV retinitis can cause a detached retina, leading to blindness in under six months.

As the disease progresses, individuals experience blurry vision, decreased peripheral vision, and light flashes. Fundus examination of the right eye showed disc oedema with full thickness mixed pattern cytomegalovirus (CMV) retinitis with vasculitis while the left eye was normal ( figure 2 ). 1 Caused by human cytomegalovirus, it occurs predominantly in people whose immune system has been compromised, 15-40 of those with AIDS. All individuals with a weakened or suppressed immune system are at risk for CMV retinitis, including individuals who are undergoing chemotherapy or who have recently had a bone marrow transplant.Ĭommon symptoms of CMV retinitis include seeing “eye floaters” or small specks in the eye. Cytomegalovirus retinitis, also known as CMV retinitis, is an inflammation of the retina of the eye that can lead to blindness. For individuals with compromised immune systems, especially due to HIV/AIDS, their bodies are unable to fight off the virus. Nearly 80 percent of all adults have antibodies for this very common virus, meaning they have been infected with the virus and their bodies have successfully fought it off. Causes and SymptomsĬMV retinitis is caused by the cytomegalovirus. The functional success rates were 77.8 and 12.5 for 23-gauge and 20-gauge vitrectomy respectively. Thanks to aggressive treatments and a new, potent combination of drugs used to treat HIV/AIDS, CMV retinitis has been reduced by more than 80 percent. The anatomical success rates at 3 and 6 months of patients who underwent 23-gauge vitrectomy was 88.9 as compared to 62.5 in patients who underwent 20-gauge vitrectomy. In the early days of the AIDS epidemic, nearly one-quarter of all individuals diagnosed with late-stage AIDS also developed CMV retinitis. Cytomegalovirus retinitis (CMVR) is an all-important blind-causing disease but was once neglected in people with acquired immune deficiency syndrome (AIDS) ( 1 ). CMV retinitis is typically associated with Acquired Immunodeficiency Syndrome (AIDS). Cytomegalovirus (CMV) retinitis is a serious disease causing compromised vision and ultimately a total loss of vision.
