About Herpetic Keratitis

Herpetic Keratitis is the number one infectious cause of corneal blindness in the U.S.  Herpes simplex virus infections are very common, with nearly 60% of the US population showing evidence of infection by age five. Approximately 1% of infected patients develop ocular outbreaks, with 20,000 primary cases of ocular herpes diagnosed in the US each year. After the primary infection, ocular HSV typically becomes latent until triggers such as stress, UV radiation, and hormonal changes reactivate the virus and cause recurrent outbreaks. Those recurrences account for an additional 28,000 cases per year in the US. The risk of blindness increases with the number and severity of recurrences, making prompt treatment imperative to limit corneal scarring and other more serious ocular complications caused by herpetic ulcers.
