Treatment herpes virus eye

This is more serious, as it is more likely to cause scarring of the cornea. Other parts of the eye are sometimes affected. Often at the same time as the cornea is infected, a minor and temporary inflammation may occur with active infection of:.

Most episodes of active infection are due to a reactivation of the virus at some point, often years after a primary infection. Symptoms include:.

You may also notice a blistery skin rash around the eyelids but not in all cases. It is usually one eye that is affected. Your family doctor will usually examine your eye with a magnifier. They may also put some stain on the front of your eye. This is used to show up any irregular areas on the transparent front part of the eye. With a herpes simplex infection they will often see a small scratch on the cornea. The typical ulcer which develops is called a dendritic ulcer. Dendritic means branching.

The ulcer is not round with a smooth edge but like a tree with many finger-like branches, as below:. If your doctor suspects a herpes eye infection you will usually be referred urgently to an eye specialist ophthalmologist. A specialist will do a detailed magnified examination of the eye. This is to confirm the diagnosis and to determine whether the infection is in the top layer of the cornea epithelial keratitis , or if the deeper layers are involved stromal keratitis.

Before you start to use any eye drops or ointment, your eye specialist ophthalmologist may make your eye numb and then gently scrape away some of the infected cells. This procedure is called debridement. Treatment is with antiviral eye ointment or drops such as aciclovir ointment or ganciclovir gel.

These do not kill the virus but stop it from multiplying further until the infection clears. You should take the full course exactly as prescribed. This is often several times a day for up to two weeks. The aim is to prevent damage to the transparent front part of the eye the cornea. Keratitis, or inflammation or infection of the eyes, has several potential causes, including bacteria, parasites, overexposure to ultraviolet UV light, or a virus specifically HSV-1 or HSV There are roughly 20, new reported cases of eye herpes in the United States every year, with 48, total reported infectious episodes.

Herpes keratitis symptoms often are misdiagnosed or even dismissed as something else. Contact lenses increase your chance of infection and re-infection. Moreover, you can discuss other corrective measures with your ophthalmologist.

With any type of herpes virus that affects humans, the virus can enter the body and remain dormant for years. Forms of physical or emotional stress typically lead to the virus becoming active, either for the first time or as a flareup. Common causes of flareups include:.

Mild or moderate symptoms from eye herpes can cause issues that are frequently mistaken for conjunctivitis. These health problems include:. Conjunctivitis is an inflammation and infection of the sclera , the white part of the eye.

It is caused by exposure to chemicals or toxins, allergies, or bacteria. If your optometrist or ophthalmologist is unsure whether you have conjunctivitis or eye herpes, they will use a lab test to make a conclusive diagnosis. This is important, as treating these conditions helps you maintain healthy eyes and clear vision, but the treatment plans are different.

Children are most likely to contract eye herpes, usually in a mild form called keratoconjunctivitis. They will have red, perhaps itchy or watery eyes, until the flareup goes away. They may have another flareup that requires treatment from their eye doctor, but for the majority of children, one or two outbreaks is all they will experience.

The herpes virus will remain dormant for the rest of their lives. Getting an accurate diagnosis and appropriate treatment plan is important because severe forms of eye herpes can move into the stroma, a deeper layer of the cornea, and lead to stromal keratitis , which is harder to treat and can cause blindness. You may also develop iridocyclitis, when herpes infects the iris.

Jeng notes. A rarer form of herpetic eye disease is disciform keratitis. These patients experience round, demarcated stromal and epithelial edema, and the formation of granulomatous keratic precipitates. These patients respond nicely to a tapered course of topical steroids. These patients must be followed carefully because they can melt and perforate.

Other rare presentations are herpetic retinitis, which is sometimes accompanied by herpes encephalitis, and there is acute retinal necrosis syndrome. Pepose adds. With varicella zoster virus, the shingles manifestation is most concerning, according to Dr.

The vaccine seems to offer protection against chicken pox in the young, but there seems to be an unintended increased risk of shingles in these folks. With the vaccine, people are also at risk for shingles at a younger age. When it affects the eye, patients can get issues ranging from glaucoma to neurotrophic keratitis to iritis. Antivirals should be prescribed for at least a week to try to prevent some of the long-term manifestations of the ocular issues of shingles.

Mah explains the mechanism behind the post-shingles eye problems. Mah continues. Jeng agrees that herpes zoster is far more complicated than herpes simplex. Epithelial keratitis caused by herpes zoster manifests in two ways. Jeng explains. It can be treated either orally, which is my preference, or topically with ganciclovir. The most common type of eye herpes is epithelial keratitis. In this type, the virus is active in the thin outermost layer of the cornea, known as the epithelium. As mentioned, HSV can also affect deeper layers of the cornea, known as the stroma.

This type of eye herpes is known as stromal keratitis. Stromal keratitis is more serious than epithelial keratitis because over time and repeated outbreaks, it can damage your cornea enough to cause blindness. Eye herpes is caused by an HSV transmission to the eyes and eyelids.

Rather, it most commonly happens after another body part — typically your mouth, in the form of cold sores — has already been affected by HSV in the past. The virus can lie dormant for a while, then reactivate from time to time.

So, eye herpes can be the result of a flare-up reactivation of an earlier infection. The risk of transmitting the virus to another person from an affected eye is low, however. Antiviral medications help minimize damage during an outbreak. Estimates vary, but approximately 24, new cases of eye herpes are diagnosed every year in the United States, according to the American Academy of Ophthalmology.

If you have symptoms of eye herpes, see an ophthalmologist or an optometrist. These are both doctors who specialize in eye health. Early treatment may improve your outlook.

Your doctor will do a thorough eye exam to evaluate your vision, sensitivity to light, and eye movements. That helps your doctor see the condition of the retina in the back of your eye. Your doctor may perform a fluorescein eye stain test.

During the test, your doctor will use an eye drop to place a dark orange dye, called fluorescein, onto the outer surface of your eye.
