What You Can Do To Help Prevent Herpes Simplex Eye Infections

Because type 1 herpes simplex virus is so common, you probably cannot prevent your first infection. Many cases are so mild that you may not know you have been exposed to HSV. Later in life, you may be able to prevent attacks by maintaining general good health and keeping stress in your life at a moderate level.

Sometimes attacks occur for no known reason and probably cannot be prevented.

• opaque cells arranged in a stellate pattern progressing to a linear branching ulcer terminal bulbs may be visible
• associated with reduced corneal sensitivity

Basics Of Hsv Keratitis

What is HSV keratitis?

HSV keratitis is an infection of the corneathe clear dome that covers the colored part of the eyethat is caused by HSV. The infection usually heals without damaging the eye, but more severe infections can lead to scarring of the cornea or blindness. HSV keratitis is a major cause of blindness worldwide 1. HSV-1, which is the type of HSV that also causes cold sores on the mouth, is the most common cause of corneal infections.

What are the symptoms of HSV keratitis?

Symptoms of HSV keratitis include 2:

• Sensitivity to light
• Watery discharge

If you experience any of these symptoms, remove your contact lenses and call your eye doctor right away. If left untreated, HSV keratitis can result in vision loss or blindness.

Where is HSV found?

HSV is only found in humans and is spread through direct contact with someone who is infected with the virus 3. Most HSV keratitis infections happen after another part of the bodymost commonly the mouth 4has already been infected by HSV 5. HSV keratitis is often the result of a flare up of the earlier infection.

What puts people at risk for HSV keratitis?

People who have had HSV keratitis are at risk for recurrences of the same infection 2. For these people, wearing contact lenses may further increase the risk 6.

People most at risk for HSV-1 are 7:

• Non-Hispanic black or Mexican American
• Born outside the United States
• Sexually active, or have had 3 or more lifetime sex partners

What Is The Outlook

The main concern with corneal infection is that it can cause scarring of the transparent front part of the eye . With scarring, the normally clear cornea can become like frosted glass. This may sometimes seriously affect vision.

• Epithelial keratitis tends to settle and go away within a few weeks. It has a good outlook and often causes little or no scarring.
• Stromal keratitis is more likely to result in corneal scarring and loss of vision.
• Recurring episodes of active infection can make any existing scarring worse.
• Prompt treatment with antiviral eye ointment or drops helps to minimise damage during each episode of active infection.

Overall, good vision remains in about 9 in 10 eyes affected by herpes simplex infection – that is, vision good enough to drive. However, severe and recurrent herpes simplex eye infections may lead to serious scarring, impaired vision and even severe sight impairment in some cases. If severe sight impairment does develop, a corneal transplant may be the only option to restore vision.

Symptoms Of A Herpes Eye Infection

Herpes eye infections, also called herpes keratitis, are similar to other types of eye infections. However, they are often more painful, and, because they risk scarring of the cornea, we recommend seeking treatment ASAP rather than waiting for an infection to clear on its own.

Symptoms of an eye infection caused by herpes include:

• Eye pain or discomfort
• Sores or lesions on lips or gums

Most herpes infections are superficial, affecting only the eyelid or the exterior lining of the eye. However, corneal infections may become more serious, resulting in scarring that permanently affects vision.

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.

Trifluridine ophthalmic option 1% .

A structural analogue of thymidine, this agent prevents viral DNA polymerase. Viroptic has much better penetration through the cornea and greater effectiveness than other topical representatives. If no response occurs in 7-14 days, consider other treatments.

Valacyclovir .

Valacyclovir is a prodrug that is rapidly converted to the active drug acyclovir. It produces a higher serum concentration of acyclovir with smaller sized oral dosing. Valacyclovir is more pricey than acyclovir however can be as reliable with an easier dosing routine. The optimum dose for ocular disease has actually not been identified.

Famciclovir .

This agent is a prodrug that, when biotransformed into its active metabolite, penciclovir, might hinder viral DNA synthesis/replication. It has actually been used successfully in the suppression of genital herpes. Its effectiveness in HSV keratitis presently is under research study.

How To Prevent Eye Infections

If you’re close to a person with one or two red eyes, avoid touching the area around your eyes until you can wash your hands first.

Prevent eye infections by washing your hands before touching your eyes or eyelids and before handling contact lenses.

You can minimize the risk of catching common bacterial or viral eye infections by using anti-infective sprays and cleansers in public areas, including day care centers and classrooms.

In general, it’s good to teach children to avoid touching their eyes without washing their hands first.

At home, if any family members have a red eye or a confirmed eye infection:

• Keep their bedding and towels clean

• Don’t let them share these items with anyone else

• Have them wash their hands often

If you wear contact lenses, follow the safety tips for good hygiene, including washing your hands before you touch your contacts.

Stay aware that sleeping while wearing contacts, even “breathable” silicone hydrogel contact lenses approved for overnight wear, can significantly increase your risk of eye infection.

Hsvk Or A Masquerader

The initial presentation of ocular HSV may or may not represent primary infection by the virus. In one study of 108 adult patients with primary ocular HSV, 84% of patients had moderate to severe conjunctivitis, 38% had moderate to severe blepharitis, 35% had a concomitant upper respiratory infection and 31% had generalized symptoms. Only 15% of patients had dendritic ulcers, while 2% had HSV endothelial keratitis and 19% had bilateral disease.14

Because of its variable presentation and ability to affect all corneal layers, HSVK has several masqueraders and differential diagnoses. For example, any keratitis that creates a dendriform lesion could be mistaken for HSV epithelial keratitis. Infectious masqueraders include Acanthamoeba keratitis, VZVK, adenovirus epithelial keratitis, Epstein-Barr epithelial keratitis, chlamydial keratitis and other varying microbial keratitis.4,12 Non-infectious differentials include Thygesons superficial punctate keratopathy, exposure keratopathy, epithelial defects from topical medications , epithelial defects due to contact lens wear, epithelial regeneration lines, epithelial basement membrane disease and recurrent corneal erosions.4,12 Appropriate patient history, demographics and a comprehensive workup will help you sift through masqueraders.
