Herpes simplex virus keratitis - External and Internal Eye
Primary infection can include a range of manifestations, such as a blistering rash on the face that may or may not involve the eye and orbit or 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 at the same time.
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.
Immunocompromised Patient Considerations:
Human immunodeficiency virus (HIV) patients have a higher rate of incidence and recurrence of HSV ocular disease (mainly reported for keratitis) and may take longer to heal, but the ocular manifestations of the disease are not notably more severe.
