CMV Retinitis

CMV or cytomegalovirus retinitis is a vision threatening virus that causes inflammation of the retina, primarily in individuals with a compromised immune system, such as those with AIDS (Acquired Immunodeficiency Syndrome).

Symptoms of CMV Retinitis

Symptoms of CMV retinitis often appear relatively suddenly. They include general blurriness, seeing flashes or floaters, sudden loss of peripheral (side) vision, or blind spots in central vision. These symptoms all appear as the virus attacks the retina, the light-sensitive layer of nerves at the back of the eye. If left untreated, the virus can cause retinal detachment and will eventually destroy the retina and damage the optic nerve, causing permanent vision loss. Usually there is no pain felt as the retinal damage is taking place. Symptoms usually start in one eye and but can spread to the other eye as well.

Causes of CMV Retinitis

Cytomegalovirus is a herpes type virus that is actually present in most adults. However, most healthy adults never experience any symptoms or problems from the virus. Individuals with a weakened immune system however, such as those with AIDS, chemotherapy or leukemia patients, newborns or the elderly are at greater risk of the virus being activated and spreading throughout the body, including the retina.

Treatment for CMV Retinitis

Treatment includes antiviral medications such as ganciclovir, foscarnet or cidofovir, which can be administered orally, via injection through a vein or directly into the eye or through a time-release implant the releases the medication at intervals. Laser surgery to improve the damaged area of the retina, such as in a retinal detachment, may also be prescribed.

Immune strengthening is also a critical part of preventing and treating CMV retinitis. Individuals with HIV or AIDS may be put on a regimen of highly active antiretroviral therapy (HAART) to boost the immune system and fight the virus. This has been shown to be highly effective in reducing the incidence of CMV retinitis in AIDS patients and reducing the damage for those that are affected.

While these treatments can stop further damage to the retina, any vision that is lost cannot be restored. Further, even if the virus is temporarily stopped, further progression may occur in the future. This is why it is critical to see a retinal specialist on a regular basis if you have had the condition or you are at risk.

Armstrong & Small Eyecare Centre - COVID-19 Update - March 18, 2020

Due to the recent COVID-19 outbreak, we have made the difficult decision to close starting Wednesday, March 18 and we are hoping (depending on the conditions) that we will re-open on Monday, April 6th.

In our attempts to be as socially distant as possible and to protect you, our staff and all of our families, we recommend staying at home and following all of the precautions that have been set out by the city, province and the nation.

If you have specific questions about glasses, contact lenses or any other non-emergency / non-essential items please email us at info@armstrongandsmall.com and we will do our best to accommodate your request. As part of our services, we are happy to provide you the option of having your contact lenses sent directly to your home. If you currently have items on order, we will be in touch with you to make arrangements.

If you are calling about a specific ocular or visual emergency such as new flashes and/or floaters, a loss in vision or a suspected eye infection, please text or call Dr. Luke Small at 204-299-6587 or Dr. Matt Lepage at 204-573-8039 who are both providing on-call emergency services through our clinic. Please do this prior to going to Misericordia or to a walk-in clinic as we attempt to reduce their patient load at this time. Obviously, if you have been recently traveling or are experiencing any symptoms related to COVID-19, they will be able to direct you where to go for the proper care.

Please stay home as much as possible and stay safe.

Thank you from your Armstrong & Small Eyecare Team.
