Cytomegalovirus
The cytomegalovirus (CMV) is related to the herpes virus and is present in almost everyone. Normally the immune system is able to fight the virus, preventing it from causing problems in their bodies. However, when the immune system is suppressed because of disease (HIV), organ or bone marrow transplant, or chemotherapy, the CMV virus can cause damage and disease to the eye and the rest of the body.

CSIGNS AND SYMPTOMS CMV retinitis usually causes symptoms, but not always. Patients with a condition that suppresses the immune system should watch for the following eye symptoms while under the care of a physician.
• Floaters (spots, bugs, spider webs)
• Light flashes
• Blind spots
• Blurred vision
• Obstructed areas of vision
• Sudden decrtease of vision DETECTION AND DIAGNOSIS Most patients with CMV retinitis are referred for eye treatment by another physician. The vitreo-retinal surgeon diagnoses CMV retinitis by thoroughly examining the back of the eye using ophthalmoscopy. Fluorescein angiography may be needed to evaluate the circulatory system of the retina. TREATMENT When managing CMV retinitis, the goal of the doctor is to slow the progression of the disease and to treat related eye problems. Anti-viral medications such as ganciclovir or foscarnet are often prescribed. These drugs can be administered orally, intravenously, injected directly into the eye or through an intravitreal implant
