One of the most important parts of the eye is the retina which is the light sensitive layer of nerves that lines the eye ball and enables us to see. The CMV retinitis is a viral infection that affects this part of the eye and is largely due to lack of immunity.


  • Blurred vision
  • Loss of side vision
  • Blind spot in the centre of vision
  • Loss of central vision
  • Begins in one eye and progresses to the other

If this infection isn’t treated, then this virus can destroy the retina and cause damage to the optic nerves which can lead to blindness over a period of time.  

Causes and diagnosis

  • This infection is caused by cytomegalovirus which is one of the herpes viruses and usually the people infected have no symptoms. In case the person has a weak immune system then there are chances of the virus getting reactivated and spreading to the retina.
  • The specialist performs a dilated eye examination to check for signs of CMV retinitis. It is a painless test where eye drops are placed to enlarge the pupils.


Although there is no specific treatment, antiviral medication taken through the mouth, vein, eye injections or implants that deliver medication. Laser surgery is common to strengthen the damaged areas of the retina.

But treatment does not bring back lost vision and chances of recurrence is common which is why regular check-ups are important to ensure the infection is under control.
