Complications of Untreated CMV Retinitis
Untreated cytomegalovirus (CMV) retinitis can lead to several serious complications that can significantly impact vision and overall eye health. Without proper treatment, the infection can progress and cause irreversible damage to the retina, the light-sensitive tissue at the back of the eye.
One of the primary complications of untreated CMV retinitis is vision loss. As the infection spreads and damages the retina, it can lead to blurred or distorted vision, blind spots, and even complete loss of sight in the affected eye. The longer the infection remains untreated, the greater the risk of permanent vision impairment.
Additionally, untreated CMV retinitis can increase the risk of other ocular complications, such as retinal detachment and macular edema. Retinal detachment occurs when the retina pulls away from the underlying tissue, causing a sudden loss of vision. Macular edema, on the other hand, is the buildup of fluid in the macula, the central part of the retina responsible for sharp vision. Both conditions can further worsen visual function and require additional medical interventions.
In severe cases, untreated CMV retinitis can also lead to complications beyond the eye. The infection can spread to other organs, such as the lungs, gastrointestinal tract, and central nervous system, causing systemic symptoms and potentially life-threatening conditions.
It is crucial to seek medical attention promptly if you experience any symptoms of CMV retinitis, such as changes in vision or eye pain. Early detection and proper treatment significantly reduce the risk of complications and help preserve vision. With advancements in medical therapies and regular follow-up care, individuals with CMV retinitis can effectively manage the infection and maintain their eye health.
