Herpes simplex virus causes two types of infections in humans. Type 1 affects the face, and type 2 affects the genitals. When the infection affects the eye, it is known as herpes simplex viral keratitis. Herpes infection is contagious and spreads through skin contact. After an initial herpes infection, the virus remains in the body in a dormant state. Reactivating triggers include stress, UV exposure, medications like steroids, trauma, etc. Herpes keratitis presents with redness of the eye, blurry vision, tearing, eye discharge and rash, eye pain, and light sensitivity. Keratitis affecting the deeper layers of the cornea can cause scarring and blindness. Oral and topical antivirals are used in the treatment.
