Cytomegalovirus retinitis
Cytomegalovirus retinitis (pronounced: sy-toe-MEG-a-low-vy-rus ret-i-NY-tis) is a serious viral infection of the retina of the eye, often seen in people with compromised immune systems, such as those with HIV/AIDS.
Etymology
The term "Cytomegalovirus" is derived from the Greek words 'cyto' meaning 'cell', and 'mega' meaning 'large', referring to the large size of the cells infected by the virus. "Retinitis" comes from 'retina' and '-itis', a suffix used in medical terminology to denote inflammation.
Definition
Cytomegalovirus retinitis is an inflammation of the retina of the eye caused by the cytomegalovirus (CMV). This condition can lead to blindness if not treated promptly. It is most commonly seen in individuals with weakened immune systems, particularly those with HIV/AIDS.
Symptoms
Symptoms of Cytomegalovirus retinitis may include floaters, flashes of light, blind spots or blurred vision. In some cases, the condition may progress rapidly, leading to a total loss of vision.
Treatment
Treatment for Cytomegalovirus retinitis typically involves antiviral medications to control the CMV infection. These may include ganciclovir, foscarnet, or cidofovir. In some cases, a surgical procedure known as a vitrectomy may be necessary.
Prevention
Prevention of Cytomegalovirus retinitis is primarily focused on maintaining a strong immune system, particularly in individuals with HIV/AIDS. This may involve antiretroviral therapy to control the HIV infection, as well as regular eye exams to detect any signs of retinitis.
