Abstract
Herpetic keratitis is the leading cause of infectious blindness around the world, the main pathogen is Herpes Simplex Virus type 1 (HSV-1). Exposure to VHS-1 worldwide is extremely common; around 90% of the adult population has been exposed to this virus at some point in their lives. The ocular infection happens mainly because of retrograde transport from the Trigeminal Ganglion to the eye, resulting in mostly epithelial herpetic keratitis. The clinical manifestations of the first episode are usually asymptomatic. Some of these patients will present with recurrences which cause symptoms, epithelial ulcers, stromal keratitis and endotheliitis. These recurrences may cause corneal opacification and blindness. An adequate diagnosis and treatment are needed to prevent the complications. This pathology is usually self limited but the use of treatments such as Acyclovir topical or orally helps diminish the symptoms and recurrences.
