What Is Herpes Of The Eye

If The Deeper Layer Of The Cornea Is Affected

Treatment is similar to epithelial keratitis . In addition to the antiviral eye ointment or drops, your specialist may add in some steroid eye drops. This helps to reduce inflammation.

Note: steroid eye drops must only be used under close supervision of an eye specialist. He or she will prescribe the correct strength and dose in conjunction with antiviral treatment. If you use steroid eye drops wrongly they can make herpes simplex infections worse!

Antiviral tablets may be used in some cases.

Deterrence And Patient Education

Educating patients and care providers about the visually devastating nature of the HSV keratitis and the need for adherence to treatment are very important. As herpes simplex virus is ubiquitous in nature and nearly impossible to avoid infection, the following measures will help in the prevention of both acquiring and recurrence of the disease.

• Oral antiviral prophylaxis of pregnant women at 36 weeks and opting for elective cesarean delivery prevents neonatal spread during birth
• Avoid oro-labial contacts of adults to newborns.
• Long term oral antiviral prophylaxis prevents recurrences in corneal graft and stromal keratitis and keratouveitis.
• Long term oral antiviral prophylaxis prevents recurrences in corneal graft following penetrating keratoplasty for uncontrolled epithelial keratitis or for dense stromal scar secondary to HSV keratitis

If The Top Layer Of The Cornea Is Affected

Treatment is with antiviral eye ointment or drops . 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 .

What Is Herpes Keratitis

Herpes keratitis is an infection of the cornea, the transparent part of the eye, caused by herpes simplex virus.

It is very contagious with no cure, meaning that you may experience flare-ups periodically throughout your life.

After the initial outbreak, the virus lies dormant in your nerve cells and can be reactivated during times of stress, hormonal changes, illnesses, pregnancy, and high sun exposure.

Typically, recurring outbreaks will not be as severe as the initial infection, but you should monitor your symptoms and seek treatment when needed to avoid health complications.

Treatment For Eye Herpes Suppresses The Virus

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.

An optometrist or ophthalmologist will look at your eyes while your symptoms are active to make a diagnosis. Typically, lab testing is not necessary, but it can be performed in cases when the virus is less active, or symptoms are less clear.

If a lab test is needed, this will be a fluorescein eye stain. Your doctor will use an orange dye that fluoresces under certain light, and apply this stain to the surface of your eye, where the epithelial layer of your cornea is. This helps your doctor see any layers of scarring that may be from past herpes outbreaks.

Treatment for eye herpes is simple. Your doctor will prescribe eye drops or oral antiviral medications, which may be taken during outbreaks to suppress the virus and promote faster healing, or consistently for several years, depending on how severe and frequent outbreaks are when you are diagnosed. It is rare that eye herpes requires further treatment like surgery, but if outbreaks lead to scarring on your cornea or inside your eye, your eye doctor may recommend a laser procedure to remove scar tissue.

Treatment Of Herpes Simplex Keratitis

• Antiviral eye drops

• Antiviral drugs taken by mouth or vein

• Corticosteroid eye drops and drops that dilate the pupil

• Sometimes removal of infected and damaged eye cells

Treatment of herpes simplex keratitis should be started as soon as possible.

The doctor may prescribe an antiviral drug, such as trifluridine eye drop or ganciclovir eye gel.

Acyclovir, another antiviral drug, can be taken by mouth or by vein . The antiviral drug valacyclovir can also be taken by mouth. Sometimes, acyclovir or valacyclovir is prescribed to prevent frequent occurrences as well as in people whose episodes have been severe enough to threaten their vision.

Deep infections that cause a lot of inflammation may require use of corticosteroid drops.

Drops that dilate the pupil, such as cyclopentolate, atropine or scopolamine, can help relieve symptoms.

Occasionally, to help speed healing, an ophthalmologist gently swabs the cornea with a soft cotton-tipped applicator to remove infected and damaged cells.

How Is It Diagnosed

The viruses have different symptoms. But each can be painful since they irritate your nerves.

Symptoms of herpes zoster ophthalmicus include:

• Severe pain on one side of the face, in your scalp, or around your eyes
• Redness, rash, or sores on your eyelids and around the eyes, especially on the forehead
• A rash on the tip of your nose
• A swollen or cloudy cornea

If symptoms involve only your eye, itâs probably herpes simplex keratitis. You might notice:

• Pain in and around one eye
• A feeling of dirt or grit in your eye
• Overflowing tears
• Pain when you look at bright light
• Cloudy or swollen cornea

Your doctor may check your eye pressure and use special dye to study the surface of your cornea.

The herpes simplex virus Herpes Simplex Virus Infections Herpes simplex virus infection causes recurring episodes of small, painful, fluid-filled blisters on the skin, mouth, lips , eyes, or genitals. This very contagious viral infection… read more never leaves the body after an initial infection. Instead, the virus remains in a dormant stage in the nerves. Sometimes, the virus reactivates and causes a recurrence and further symptoms.

Primary herpes simplex eye infections usually occur in children and cause a mild keratoconjunctivitis, which is inflammation of the cornea and of the conjunctiva .

The primary infection resolves without treatment and the inactivated virus hides in the nerve roots. Several types of stress can reactivate the virus:

• Exposure to intense light

• Significant physical stress

• Immunosuppression

• Use of corticosteroids

If the infection reactivates, it can affect the cornea more seriously and may result in temporary or permanent visual loss.

Herpes simplex keratitis is a major cause of blindness worldwide.

Recovering From Eye Herpes

If youre treating your eye herpes with eye drops, you may need to put them in as often as every 2 hours, depending on the medication your doctor prescribes. Youll need to keep applying the drops for up to 2 weeks.

With oral acyclovir, youll take the pills five times per day.

You should see improvement in 2 to 5 days. The symptoms should be gone within 2 to 3 weeks.

After a first bout of eye herpes, about 20 percent of people will have an additional outbreak in the following year. After multiple recurrences, your doctor may recommend taking antiviral medication daily.

This is because multiple outbreaks damage your cornea. Complications include:

• numbing of the corneal surface
• perforation of the cornea

If the cornea is damaged enough to cause significant vision loss, you may need a corneal transplant .

How Contagious Is Herpes In The Eye

Herpes simplex keratitis doesnt usually spread to the other eye and its unlikely that youd pass it on to another person. So you dont need to worry about being contagious while youre experiencing symptoms. However, the herpes simplex virus can be contagious, so if you have a cold sore you should try to avoid touching your eyes.

Herpes zoster ophthalmicus doesnt usually spread to the other side of the face or eye and its rare to pass on to another person. But if the blisters from the rash weep, the fluid is contagious so could be passed on to someone else by touch. This could cause the other person to experience chicken pox or shingles .

A Review Of How To Decide Which Oral And Topical Agents To Use Based On The Presentation

Herpes simplex and herpes zoster viruses can have many ocular manifestations, some of which are serious and vision-threatening. Both conditions have the potential to be chronic and recurrent, as well. Here, experts share the protocols they use when dealing with these sometimes challenging cases.

Herpes Simplex

Cornea specialist Francis Mah, in practice in La Jolla, California, notes that the live virus can cause epithelial keratitis and other ocular manifestations. The classic herpes simplex presentation is a dendrite that can form on the surface of the cornea. The treatment for this is epithelial scraping with an instrument such as a Kimura spatula, along with trifluridine dropswhich was a huge advance at the time they were introducedand oral antivirals, such as acyclovir, valacyclovir and famciclovir, the most commonly used treatments among cornea specialists. A newer agent, ganciclovir gel, is also an option. Typically, people will develop a dendrite when theyre run down, when theyve traveled, and when they are stressed or sick, he says. Sunlight can also stimulate it. Dendrites dont cause much pain. The main symptom will be a change in the patients vision.

Patients with ocular herpes can also develop endotheliitis. This causes corneal swelling because endothelial cells become stunned and dont work anymore, Dr. Jeng notes. Its generally treated with both oral acyclovir as well as topical steroids for the inflammation.

Can Herpes Simplex Eye Infection Come Back

Some people develop repeated episodes of active infection. As mentioned above, these occur if the virus reactivates from time to time – similar to cold sores. A recurrent infection may occur any time between a few weeks and many years after the first active infection.

At least half of people who have one episode of active infection will have a recurrence within 10 years of the first. Recurrences occur more often in some people than others.

If recurrences are frequent or severe, your eye specialist may advise that you take antiviral tablets each day to prevent episodes of active infection. Studies have shown that, on average, the number of recurrences is roughly halved in people who take regular antiviral tablets.

Some people say that episodes of active herpes infection may be triggered by strong sunlight. So, wearing sunglasses may also help to prevent recurrences. It is also possible that active infection may be triggered if you are run down or unwell for another reason. However, the evidence for this is limited. Some women find that they get recurrences around the time of their period but again there is limited evidence to support this.

If a recurrence does occur, each episode is treated as described above.

Causes & Symptoms Of Eye Herpes

Keratitis, or inflammation or infection of the eyes, has several potential causes, including bacteria, parasites, overexposure to ultraviolet light, or a virus .

There are roughly 20,000 new reported cases of eye herpes in the United States every year, with 48,000 total reported infectious episodes.

Herpes keratitis symptoms often are misdiagnosed or even dismissed as something else. Its important to remain vigilant and consult your medical service provider if you experience symptoms that mirror those of eye herpes, such as:

• Redness in the eyes
• Oversensitivity to light

Contact lenses increase your chance of infection and re-infection. If youre diagnosed with eye herpes and wear contact lenses, you should discard them and get new ones. 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:

• Emotional or mental stress.
• Physical trauma to the body, like an injury or surgery.
• Exposure to UV light, including being outdoors or in a tanning bed.
• Some medications.

Mild or moderate symptoms from eye herpes can cause issues that are frequently mistaken for conjunctivitis. These health problems include:

How Kirk Eye Center Treats Hsv

Sometimes herpes simplex eye infections go away without any treatment. Other times your doctor will prescribe medicines in the form of eye drops or ointments to kill the virus. To help speed up healing, your eye doctor may scrape the blisters away with a cotton swab. If your eyes do not get better with these treatments, you may need to take medicine in pill form.

One type of herpes simplex destroys cells in the eyes. For this condition your eye doctor may recommend that you take an additional medicine to help prevent serious problems. However, corticosteroids should not be taken for other forms of HSV. Be sure that your eye doctor knows about all your symptoms.

Severe cases may require surgery. Some doctors recommend keratoplasty if the cornea has been severely scarred. They may prescribe pills to reduce the chance of HSV in the transplant.

How Long Do The Effects Last

After the first infection, HSV may not cause any problems for months or years. Then sores may reappear when your immune system is weakened by disease or stress. Sometimes HSV is active but you do not have any blisters.

The effects of HSV vary greatly from person to person. Your symptoms may go away in a few days or weeks. You may have only one attack after your initial infection in childhood. However, you may have a recurrence whenever your immune system is weakened or for unknown reasons.

What Are The Symptoms And Signs Of A Herpes Simplex Eye Infection

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

• Redness of the eye – mainly around the transparent front part of the eye .
• Ache or pain in the eye.
• Discomfort when opening the eyes in bright light.
• Watering of the eye.

Can Eye Herpes Be Prevented

While there is no foolproof way to prevent an eye herpes infection or any other type of eye infection, for that matter there are steps you can take to reduce your risk.

The most important thing to remember is to keep your eyes and hands clean . Furthermore, it’s critical that you avoid touching your eyes if you or someone around you has an outbreak.

If you wear contact lenses, be sure to follow your eye doctor’s instructions on contact lens care. Do not wear them longer than recommended and do not wear them while swimming, as chemicals and germs in the water can damage the lens, irritate your eyes, and cause an infection in contact lens wearers.

Herpes Simplex Eye Infections: How To Tell The Difference

If youre prone to getting fever blisters, especially when you are sick, stressed out, or are overly exposed to the sun, you most likely carry the herpes simplex 1 virus. Those who are susceptible to herpes simplex 1 carry it in their bodies, where the virus remains dormant in tissue cells until activated. Therefore, anything that compromises the immune system, or a weakness in affected tissue, has the potential to activate the virus.

The most common sources of viral activation of the herpes simplex 1 virus are:

• Illness or a fever
• Direct trauma to the affected tissue
• Certain types of medication
• Suppressed immune system

Once a lesion or blister is apparent, you are contagious. As long as you have a blister or lesion on your lips, you can spread it to others via touch, kissing, or sharing drinks. Unfortunately, you can also spread it to other parts of the body, such as your eyes, by rubbing your eyes or touching the surrounding eye tissue after touching or making direct contact with an active blister or lesion.

When the virus makes its way to your eye, it will most likely infect the eyelid, conjunctiva , and the cornea. Infections deeper inside the eye are less common.

Reduce Your Risk Of Exposure To Eye Herpes

There are no clear ways to prevent the spread of herpes keratitis, but there are some steps you can take to keep your eyes safe.

• If you have cold sores, avoid touching your eyes. Wash your hands after you touch your lips during an outbreak to prevent spreading the virus to other areas.
• Do not share eye drops or eye makeup with others. The herpes virus can be transferred this way.
• Keep your contact lenses clean, as recommended by your optometrist. If you experience a herpes outbreak, throw out that pair of contacts.

If you are cautious, you can avoid transferring the virus to other areas of your body. It does take vigilance during outbreaks.

In the first year after contracting eye herpes, 20 percent of people will experience a recurrence of symptoms. If outbreaks become frequent, they can be managed with regular, often daily, medication. Otherwise, your doctor will prescribe medication that you will take only as needed, during your less frequent outbreaks.

For some people, the outbreaks are more frequent and more severe initially. Then, they stabilize over time and become less frequent.

While you may never need medication to treat eye herpes, it is important to get an appropriate diagnosis if you experience the symptoms listed above. Having more than one outbreak puts you at risk for scarring inside your cornea and other parts of your eye, which can lead to serious vision loss over time.
