• #1 HSV Keratitis: An Important Infectious Cause of Blindness

  https://www.uspharmacist.com/article/hsv-keratitis-an-important-infectious-cause-of-blindness

  An estimated 500,000 people in the United States have herpes simplex virus (HSV) ocular disease. Each year about 50,000 new and recurring cases are diagnosed, with their treatment costing the nation approximately $17.7 million annually. Ocular HSV is considered the most common cause of infectious corneal blindness in the U.S. […] Ocular HSV can cause disease in any layer of the eye; most cases have been attributed to HSV-1. Common manifestations include follicular conjunctivitis, blepharitis, keratitis, and uveitis. HSV epithelial (dendritic) keratitis involves inflammation of the cornea with a characteristic dendritic (branched like a tree) ulceration. When the matrix or supporting tissue of the eye becomes involved, the condition is referred to as stromal keratitis; HSV stromal keratitis accounts for considerable visual morbidity, medical expense, and lost productivity among otherwise healthy individuals.

  Herpes simplex ophthalmicus is an eye infection by the herpes simplex type 1 and type 2 viruses. […] Herpes simplex ophthalmicus is caused by a neurotrophic double-stranded DNA virus with an icosahedral capsid surrounded by a poorly defined tegument (covering). Two types of herpes simplex virus (HSV) affect humans, HSV type 1 (HSV-1) and HSV type 2 (HSV-2). […] Primary infection occurs in neonates as ophthalmia neonatorum or children less than five years of age as blepharoconjunctivitis. The virus ascends through the cutaneous nerves to stay latent in the trigeminal ganglion. […] Viral replication is triggered by conditions like fever, menstruation, irradiation, stress, steroid treatment, immunocompromised conditions, etc. to cause secondary infection in adults. […] Secondary herpes simplex ophthalmicus manifests most commonly as epithelial dendritic keratitis and its recurrences as stromal keratitis.

  Herpes simplex virus keratitis is a viral infection of the cornea (the clear surface, or window of the eye). It is usually caused by the herpes simplex virus (HSV-1), the same virus that causes cold sores. […] HSV-1 is a very common virus, passed on by direct skin-to-skin contact. Most people are infected by the time they are 60 but only one in three will notice any symptoms. After the first infection, the virus remains in the nerves of the face and can re-emerge at any time. It can cause a cold sore, or an ulcer in the eye. […] If you have HSV keratitis, it can become a recurrent problem. Similar to cold sores, the virus can re-emerge at any time. Around half the people who get HSV keratitis will get it again within five years. […] Severe or repeated episodes can result in scarring of the cornea, which can cause blurred vision.

  Cold sores are caused by certain strains of the herpes simplex virus (HSV). HSV-1 usually causes cold sores. HSV-2 is often the cause of genital herpes. But either type can spread to the face or genitals through close contact, such as kissing or oral sex. Shared eating utensils, razors and towels can also spread HSV-1. […] Cold sores are most likely to spread when you have oozing blisters. But you can spread the virus even if you don’t have blisters. Many people who are infected with the virus that causes cold sores never develop symptoms. […] Once you’ve had a herpes infection, the virus can hide in nerve cells in the skin and may cause another cold sore at the same place as before. A return of cold sores may be triggered by: Viral infection or fever. Hormonal changes, such as those related to a menstrual period. Stress. Fatigue. Being in the sun or wind. Changes in the immune system. Injury to the skin. […] The virus can sometimes cause eye infection.

  Eye herpes, also known as ocular herpes or herpes simplex keratitis, is an eye infection caused by the herpes simplex virus (HSV). […] Eye herpes is caused by the herpes simplex virus (HSV). While there are two forms of HSV that can cause eye herpes, it is usually caused by HSV-1, the same virus that causes oral herpes (cold sores or fever blisters). […] While HSV-1 can be transmitted directly to the eye such as by touching a cold sore on the mouth and then touching the eye, eye herpes is often the result of a flare-up of an earlier HSV-1 infection in another part of the body (usually the mouth). […] A flare-up, or breakout, can occur if the virus starts to multiply or moves from one area of the body to another. Flare-ups can be random, or they can be triggered by: […] HSV is typically infectious during the five to 10 days the skin lesions are healing, as well as during asymptomatic shedding in saliva.
