Synopsis

Herpes simplex virus (HSV) infection is one of the most common viral infections of the eye and periocular skin. The majority of people over the age of 60 will be seropositive for HSV-1. Infection tends to follow the distribution of the trigeminal nerve. Most ocular infections are due to HSV-1; HSV-2 can also cause infection but is much less prevalent. Primary infection can range from a blistering rash on the face that may or may not involve the eye and orbit to an upper respiratory tract infection that goes undiagnosed as HSV. In a small percentage of the population, HSV can return to involve the eye at any time after the primary infection. This will typically involve only one eye; it is very rare for HSV to involve both eyes. Recurrent bouts of HSV keratitis can cause permanent corneal scarring and loss of vision. Many people believe that stress, sunlight, and illness induce recurrence, but this has not been corroborated in scientific literature.

Patients will often present with foreign body sensation, light sensitivity, poor vision, and a red eye. Many times, patients will report a history of similar episodes in the past.
