Measles has been linked to serious eye damage and visual loss, with outbreaks emerging across the US. The disease’s symptoms often precede a telltale rash. Key signs of measles include cough, coryza (runny nose), and conjunctivitis (pink eye).
The virus can infect the cornea, causing redness, pain, and light sensitivity. In severe cases, ulcers and scarring can lead to permanent vision loss. Measles also affects the retina, leading to hemorrhages and necrosis that result in vision loss.
Complications from measles brain infection can damage optic nerves and visual cortexes, affecting recovery. A rare condition, subacute sclerosing panencephalitis (SSPE), can cause eye damage years after initial infection.
Those most at risk for measles-related eye damage include malnourished children, those with vitamin A deficiency, immunocompromised individuals, and unvaccinated people. As of now, there is no specific antiviral treatment, but the MMR vaccine protects against measles and its complications.
