Cytomegalovrius Retinitus (CMV)

What is CMV?

CMV stands for Cytomegalovirus Retinitis, and it is a serious eye infection of the retina. The retina is the light-sensing nerve at the back of the eye. When this eye infection invades the retina, it starts to compromise the photoreceptors in the eye that allow people to see. This doesn’t cause any pain for those experiencing it, but it causes a noticeable loss of peripheral vision and reduced visual acuity. Eventually, it can lead to blindness. CMV retinitis is caused by cytomegalovirus. This is a type of herpes virus that infects adults. The vast majority of people with this virus show no signs or symptoms. For people who have weakened immune systems, the virus can activate and spread to the retina. This leads to possible vision-threatening problems. 

Symptoms of CMV?

  • Appearance of floaters
  • Loss of peripheral vision
  • Blind spots
  • Loss of central vision
  • Blurry vision
  • Light flashes
  • Sudden loss of vision

Who is at Risk for CMV?

CMV Retinitis is a threat to people who have weakened immune systems. People with HIV/AIDS, cancer, or recipients of organ transplants are at an increased risk for this condition. This condition is very serious, without treatment, it can lead to complete blindness within two to six months. 

How to Treat CMV?

To diagnose this eye infection, your ophthalmologist at Boston Eye Group will use a dilated eye examination. During this treatment, eye drops will be placed in the eye to dilate (enlarge) your pupils. Then the ophthalmologist will examine the eye and retina for any signs of CMV retinitis. Part of treating this infection is strengthening your immune system. You can do this through vitamins or medications. There are also specific CMV medications available to treat this condition. Often, patients may require laser eye surgery to strengthen the retina if damage has occurred.
