Ocular herpes, herpes that affects the eye, is usually caused by the same virus responsible for cold sores on the lip, herpes simplex virus type 1. This type of herpes simplex virus can cause inflammation and scarring of the cornea that sometimes is referred to as a cold sore on the eye. Ocular herpes, which usually affects one eye, is not a sexually transmitted disease. It’s spread by contact with people who have the virus. Herpes of the eye or ocular herpes can be transmitted through close contact with an infected person whose herpes virus is active.
Previous studies show that once people develop ocular herpes, they have up to a 50 percent chance of having a recurrence. This second flare-up could come weeks or even years after the initial occurrence of ocular herpes. The Although ocular Herpes is listed as a “rare disease” by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH), meaning that Ocular Herpes, or a subtype of Ocular Herpes, affects less than 200,000 people in the US population the National Eye Institute (NEI) an estimated 400,000 Americans have experienced some form of ocular herpes or eye herpes, with close to 50,000 new and recurring cases occurring each year.

Forms of Eye Herpes or Ocular Herpes

Ranging from a simple infection to a condition that can possibly cause blindness, there are several forms of ocular herpes or eye herpes:
1st type of Ocular Herpes or Eye Herpes: Herpes keratitis is the most common form of eye herpes and is a viral corneal infection. Ocular herpes in this form generally affects only the top layer, or the epithelium, of the cornea, and usually heals without scarring.
2nd type of Ocular Herpes or Eye Herpes: Stromal keratitis occurs when the herpes infection goes deeper into the layers of the cornea. This can lead to scarring, loss of vision and, occasionally, blindness. Stromal keratitis is a type of ocular herpes that is thought to be caused by a late immune response to the original herpes infection. Although the condition is rare, the NEI reports that stromal keratitis is the leading cause of corneal scarring that subsequently causes blindness in the United States.

Stromal keratitis occurs when the herpes virus penetrates deeper into the layers of the cornea. Around 25 percent of people with ocular herpes develop this complication, the Massachusetts Eye and Ear Infirmary of Harvard University states.
An immune reaction occurs to the herpes virus that attacks the cornea causing scarring; this complication is the most common infectious cause of blindness related to the cornea. Steroid drops may help reduce inflammation, but severe scarring may lead to a need for corneal transplantation.
3rd type of Ocular Herpes or Eye Herpes: The third type of ocular herpes is iridocyclitis. Iridocyclitis is a serious form of eye herpes where the iris and surrounding tissues inside the eye become inflamed, causing severe sensitivity to light, blurred vision, pain and redness. Iridocyclitis is a type of uveitis that affects the more frontal portions of the inside of the eye.
When this infection occurs in the retina or the inside lining of the back of the eye, it is known as herpes retinitis.

Eye Herpes Symptoms and Signs

Various signs and symptoms are associated with an eye herpes or ocular herpes outbreak. You may experience inflammation of the cornea, which can cause an irritation or sudden and severe ocular pain. Also, the cornea can become cloudy, leading to blurry vision.
Other characteristics of eye herpes or ocular herpes include:
•    Swelling around the eyes
•    Tearing
•    Recurrent eye infections
•    Irritation
•    Foreign body sensation
•    Eye redness
•    Eye sores
•    Watery discharge
•    Sensitivity to light
Due to these numerous ocular herpes symptoms, your eye doctor may overlook an initial diagnosis of ocular herpes in its very early stages.
Ocular herpes is a common manifestation of the herpes virus responsible for cold sores, but can cause much more serious problems than a cold sore on the lip; corneal infection with the herpes virus is a serious complication that can lead to blindness. Treating the ocular herpes virus helps prevent it from coming back again or from affecting the other eye.

Herpes has various types and various herpes symptoms. For each kind of herpes, there are corresponding herpes signs and herpes symptoms. Herpes Simplex Virus infection causes several distinct medical disorders. Common herpes infection of the skin or mucosa may affect the face and mouth (orofacial herpes), genitalia (genital herpes), or hands (herpes whitlow). More serious disorders occur when the herpes virus infects and damages the eye (herpes keratitis), or invades the central nervous system, damaging the brain (herpes encephalitis). Herpes patients with immature or suppressed immune systems, such as newborns, transplant recipients, or AIDS herpes patients are prone to severe complications from herpes simplex virus infections. Herpes Simplex Virus infection has also been associated with cognitive deficits of bipolar disorder, and Alzheimer’s disease, although this is often dependent on the genetics of the infected person.

With these various herpes types and herpes symptoms, how does one diagnose herpes? Primary orofacial herpes is readily identified by clinical examination of persons with no previous history of lesions and contact with an individual with known Herpes Simplex Virus 1 infection. The appearance and distribution of sores in these individuals typically presents as multiple, round, superficial oral ulcers, accompanied by acute gingivitis. Adults with non-typical presentation are more difficult to diagnose. Prodromal herpes symptoms that occur before the appearance of herpetic lesions help differentiate herpes simplex virus symptoms from the similar herpes symptoms of other disorders, such as allergic stomatitis. When lesions do not appear inside the mouth, primary orofacial herpes is sometimes mistaken for impetigo, a bacterial herpes infection. Common mouth ulcers (aphthous ulcer) also resemble intraoral herpes, but do not present a vesicular stage.

Genital herpes can be more difficult to diagnose than oral herpes since most herpes simplex virus 2infected persons have no classical herpes symptoms. Further confusing diagnosis, several other conditions resemble genital herpes, including lichen planus, atopic dermatitis, and urethritis. Laboratory testing is often used to confirm a diagnosis of genital herpes. Laboratory tests include: culture of the herpes virus, direct fluorescent antibody (DFA) studies to detect herpes virus, skin biopsy, and polymerase chain reaction (PCR) to test for presence of viral DNA. Serological tests for antibodies to herpes simplex virus are rarely useful to diagnosis and not routinely used in clinical practice, but are important in epidemiological studies. Serologic assays cannot differentiate between antibodies generated in response to a genital virus or an oral Herpes simplex virus infection, and as such cannot confirm the site of herpes infection. Absence of antibody to HERPES SV-2 does not exclude genital herpes infection because of the increasing incidence of genital herpes infections caused by HERPES SV-1.

Prevention of Herpes Transmission

Although herpes is a very dangerous and complicated disease, herpes can still be prevented and treated. Below are various ways on how to prevent herpes.

Barrier protection, such as a condom, can reduce the risk of herpes transmission.

For genital herpes, condoms are highly effective in limiting transmission of herpes simplex infection. The herpes virus cannot pass through latex, but a condom’s effectiveness is somewhat limited on a public health scale by their limited use in the community, or the base of the penis or testicles not covered by the condom may come into contact with free herpes virus in vaginal fluid of an infected female. The use of condoms or dental dams also limits the transmission of herpes from the genitals of one partner to the mouth of the other (or vice versa) during oral sex.

As with almost all sexually transmitted herpes infections, women are more susceptible to acquiring genital HERPES SV-2 than men. On an annual basis, without the use of antivirals or condoms, the transmission risk of HERPES SV-2 from infected male to female is approximately 8-10%.

To prevent newborn herpes infections, seronegative women are recommended to avoid unprotected oral-genital contact with an HERPES SV-1 seropositive partner and conventional sex with a partner having a genital herpes infection during the last trimester of pregnancy.

Additional information on genital herpes prevention can be found at the cdc website.

Herpes is an infection that is caused by a herpes simplex virus (HSV). There are two types of herpes disease. The first herpes type is oral herpes which is commonly caused by herpes simplex type 1 and the second type of herpes is genital herpes which is commonly caused by herpes simplex type 2. Oral herpes causes herpes cold sores around the mouth or face. Genital herpes on the other hand affects the genitals, buttocks or anal area. Genital herpes is a sexually transmitted disease (STD). You can get it from having sex, even oral sex. The herpes virus can spread even when herpes sores are not present. Mothers can also infect their babies with herpes virus during childbirth.

Some people have no herpes symptoms. Others get herpes sores near the area where the herpes virus has entered the body. They turn into herpes blisters, become itchy and painful, and then heal. The herpes virus can be dangerous in newborn babies or in people with weak immune systems.

Most people have herpes outbreaks several times a year. Over time, you get herpes outbreaks less often. Medicines to help your body fight the herpes virus can help lessen herpes symptoms and decrease herpes outbreaks. Correct usage of latex condoms can reduce, but not eliminate, the risk of catching or spreading herpes.

However herpes is not an easily identifiable sexually transmitted disease. Herpes can actually be confused with some other medical conditions. Listed below are some conditions that are sometimes mistaken for herpes:
Condition Confused with Herpes #1: Canker sores – (aphthous ulcers), this usually occurs inside the mouth and are gray with a distinct edge, and usually heals within 10 to 14 days without treatment. Canker sores are not a form of oral herpes but it is often confused and mistaken for herpes. This medical condition is not considered to be contagious unlike herpes cold sores and mouth herpes which are caused by the herpes simplex virus and can be very contagious.
Condition Confused with Herpes #2: Bacterial or yeast infections is another type of medical condition that is sometimes confused with genital herpes,  but do not usually produce blistering like herpes.
Condition Confused with Herpes #3: Impetigo is a highly infectious bacterial disease that can also be confused with herpes sometimes. This disease is more common among children often producing crusty blisters, which is one of the symptoms of herpes.
Condition Confused with Herpes #4: Syphilis, a bacterial infection, causes chancres sometimes mistaken for blisters caused by genital herpes. Unlike genital herpes though, Syphilis does not usually produce a cluster of blisters, and it usually responds well to antibiotics.
Condition Confused with Herpes #5: Molluscum contagiosum (molluscum) – like herpes, molluscum is a viral infection of the skin. Unlike herpes however, molluscum produces lesions that are raised, with a central dimple.
Condition Confused with Herpes #6: Genital Warts
Genital warts are another medical condition that can be confused with herpes. Unlike herpes though, this disease causes growth of skin-colored, cauliflower-like masses of various sizes and shapes. Symptoms may occur several weeks and even months after being exposed to the human papilloma virus (HPV) and include itching or burning around the genitals and painless growths in either sex, usually on damp or moist surfaces of the body.

For a better idea of what herpes is and how to recognize the herpes virus it is always advisable that you research the symptoms of herpes virus, and view and compare herpes pictures to have a clear idea of what a herpes infection is.
If you think that you may have a sexually transmitted disease you can visit the Sexually Transmitted Disease Resource Center for information, pictures and support relating to all the most common STDs.
If you suspect that you may have genital herpes, an infection caused by the herpes virus or another STD please contact your local health care provider for a professional diagnosis.

Mistaken Symptoms of Herpes

There are symptoms of other diseases that can be mistaken for herpes outbreaks such as insect bites, jock itch, abrasions, razor burn, yeast infections, haemorrhoids and ingrown hair follicles.
Should any of these symptoms occur, consult your doctor or other healthcare provider immediately. Genital herpes should be diagnosed and treated professionally.

Choosing the right therapy for Herpes Simplex Virus depends on the site of the herpes infection and whether the attack is primary or recurrent. To be effective against recurrent Herpes Simplex Virus infection, treatment of herpes must be initiated in the first week of a primary herpes infection. Later herpes treatment has limited effect in preventing recurrent herpes infection.

Genital herpes is usually caused by Herpes Simplex Virus 2, but the percentage of genital Herpes Simplex Virus-1 case are rising, and new Herpes Simplex Virus 1 genital cases now equal or exceed those caused by Herpes Simplex Virus 2. Since there is no difference in herpes treatment, however, differentiating between genital herpes infections caused by Herpes Simplex Virus-1 or Herpes Simplex Virus-2 has little practical value.

Even if you don’t ever have herpes outbreaks, there may be some benefit to using daily suppressive therapy. This is because even people who have never had a herpes outbreak can transmit the herpes simplex virus to their partner.

Some people think they can only transmit herpes to their partner if they have a herpes outbreak, or in the prodromal period immediately before and then again right after a herpes outbreak. They’re wrong. Genital herpes can be transmitted at any time which is why some individuals who have many sexual partners or whose partners are not infected with the herpes simplex virus may decide to use suppressive therapy against the Herpes Simplex Virus even though they do not have any herpes symptoms.

Although herpes can be transmitted at any time, people with herpes are not equally infectious at all times. In general, a person is most infectious during a herpes outbreak, in the period immediately before and after a herpes outbreak, and in the first year after he is infected, but he still can transmit the herpes simplex virus at other times. Furthermore, some people don’t recognize when they are having a herpes outbreak. One study of 53 individuals who tested positive for genital herpes, but who had said they did not actually have herpes outbreaks, found that half them actually were having herpes outbreaks but didn’t realize it. However, even with that complication aside, six out of seven of the individuals who had no signs of clinical herpes were still found to be shedding herpes simplex virus.

Unfortunately, many patients and many physicians, are unaware of both the risk of asymptomatic herpes transmission and how effective herpes suppressive treatment can be in preventing it. If you are living with herpes and have one or more uninfected sexual partners, consider discussing the possible advantages of daily herpes suppressive therapy with your doctor. Condoms aren’t 100% effective at preventing the spread of herpes simplex virus, since it is transmitted from skin to skin. So remind him, or her, that 70% of new herpes infections are acquired from people who have no herpes symptoms at the time of herpes transmission and that herpes suppressive therapy has been shown to reduce the likelihood of herpes transmission by half or more.

Daily long-term preventive therapy, called herpes suppressive therapy, may be appropriate in certain patients to prevent severe long-lasting herpes recurrences, to reduce the risk of transmitting the herpes virus, and to improve quality of life. Acyclovir is the standard agent, but famciclovir and valacyclovir are also effective. In some studies, herpes suppressive therapy using acyclovir has reduced the frequency of herpes recurrence in 80% of patients and prevented herpes recurrence altogether in up to 30%. In one study of famciclovir, after a year, up to 80% of patients had no herpes recurrences. In others trials using valacyclovir, patients preferred herpes suppressive therapy and it was more effective than intermittent treatment.

If a herpes infection occurs during herpes suppressive therapy, healing time is quicker and symptoms of herpes are less severe. Herpes suppressive therapy may also reduce the risk for development of drug-resistant viruses compared to intermittent treatments.

Once the herpes disease is under control, some physicians gradually decrease the dose of the drug used in herpes suppressive therapy. In general, people stop taking herpes suppressive therapy after about two years. Some, however, stay on this herpes therapy for many more years.  The suppressive therapy herpes treatment is expensive. And, since the frequency of herpes recurrences diminishes over time without herpes suppressive therapy, lifelong use of drugs is not generally recommended. Some experts warn, however, that unless herpes suppressive therapy becomes widespread and prolonged, transmission of the herpes simplex virus will remain a major health problem and the prevalence of Herpes Simplex Virus-2 infection will not significantly decrease.
