Herpes Simplex Eye Infections- There are two types of herpes simplex virus (HSV). HSV-1 mainly causes infection above the waist (characteristically the face, lips and eyes) and is spread by saliva. Epithelial keratitis is the most common ocular manifestation, occurring in up to 80 of cases. Indeed, it is the most common infective cause of blindness due to corneal disease in high-income countries. Caused by the type 1 herpes simplex virus, eye herpes (ocular herpes) is a common, recurrent viral infection affecting the eyes. This type of herpes virus can cause inflammation and scarring of the cornea that sometimes is referred to as a cold sore on the eye. Stromal keratitis occurs when the infection goes deeper into the layers of the cornea. Transmission may still occur when symptoms are not present. In HSV-1-infected individuals, seroconversion after an oral infection prevents additional HSV-1 infections such as whitlow, genital herpes, and herpes of the eye.
There are two types of Herpes Simplex Viruses (HSV). HSV Type 1 causes cold sores and can affect the face and eyes. In most cases, the infection is just in the top layer of the cornea and is called epithelial keratitis. It is not known why reactivation occurs in some people, although it may be related to illness, stress, or trauma. Oral herpes is a common infection of the mouth area. It is caused by the herpes simplex virus type 1 (HSV-1). It occurs in or near the eye. You have a weakened immune system due to certain diseases and medicines.

They might also send samples of the blister to a laboratory to test specifically for HSV-1. Recurrent herpes simplex labialis can be dangerous if the blisters or sores occur near the eyes. Herpes simplex is commonly referred to as cold sores or fever blisters, as recurrences are often triggered by a febrile illness, such as a cold. Primary attacks of Type 1 HSV infections occur mainly in infants and young children. Eye infection. This page contains notes on herpes simplex viruses. The gravest form of ocular herpetic disease occur when the virus spreads to the anterior chamber. The mechanism of pathogenesis is unknown but there appears to be an intense immunological reaction. It was said that HSV-1 causes infection above the belt and HSV-2 below the belt. In fact, 40 of clinical isolates from genital sores are HSV-1, and 5 of strains isolated from the facial area are HSV-2. Recurrent intra-oral ulcers are rarely caused by HSV. Beyond the neonatal period, most primary HSV-1 infections occur in infancy and childhood and are transmitted primarily by contact with infected saliva. Herpes simplex virus type 1 (HSV-1) typically causes infection above the waist and the infections are localized to mouth and oropharynx, whereas herpes simplex virus type 2 (HSV-2) usually causes genital infections and can also cause CNS or disseminated disease in neonates. Most infections are caused by HSV-1 and are localized to the mouth and oropharynx. Skin, eye, and mucous membrane (SEM) disease: Infection with herpes simplex virus limited to SEM historically accounts for about 20 of all neonatal herpes simplex virus infections. The herpes simplex virus-1 (HSV-1) causes oral herpes; both HSV-1 and herpes simplex virus-2 (HSV-2) cause genital herpes. Being infected with the virus does not necessarily mean that herpes sores will occur.

The cold sore virus is a different strain of herpes than the one associated with sexually transmitted disease; ocular herpes is not an STD. Cold sores, however, no matter where they occur, may come back.

Stromal disease can occur due to the virus itself or due to the immune mediated inflammatory response to infection 11. Herpes simplex virus type 2 (HSV-2) infection is responsible for significant neurological morbidity, perhaps more than any other virus.
