Challenges And Recent Progress In Controlling Ocular Herpes
Ocular herpes is currently an infection for life. For a very long time, finding a cure for HSV has been a significant unmet need for physicians and scientists alike. Currently, with the exception of VZV, there is no vaccine for herpesvirus infections . Also, the currently approved therapies to control ocular herpes provide limited efficacy and often have to be combined with steroids to reduce symptoms especially during the recurrent cases of HSK. In general, current treatment modalities reduce the symptoms only by a few days . Likewise, long-term use of steroids has its own serious side effects, which includes increase in intraocular pressure and possible onset of secondary glaucoma . While the clinically approved drugs, mainly nucleoside analogs, are clearly beneficial , they also suffer from their share of pitfalls. Development of resistance against the most commonly used drug, acyclovir, is common and long-term use of it is known to cause renal toxicity . Thus, there is a great need to develop new antiviral therapies for herpesvirus infections. Both currently approved as well as some emerging therapies are discussed below.
When You Must Not Take Them
- Do not take Valtrex tablets if you have ever had an allergic reaction to valaciclovir, aciclovir or any of the ingredients listed at the end of this leaflet.
- Symptoms of an allergic reaction may be mild or severe. They usually include some or all of the following: wheezing, swelling of the lips/mouth, difficulty in breathing, hay fever, lumpy rash or fainting.
- Do not take Valtrex tablets if you are pregnant, trying to become pregnant or breast-feeding, unless your doctor says you should.
- Your doctor will discuss the risks and benefits of using Valtrex tablets when pregnant and during breast-feeding.
- Do not take Valtrex tablets after the expiry date printed on the pack.
- If you take it after the expiry date has passed, it may not work as well.
- Do not take Valtrex tablets if the packaging is torn or shows signs of tampering.
- If you are not sure whether you should be taking Valtrex, talk to your doctor.
What Are Medical Treatments For Eye Herpes
The doctor may prescribe an antiviral eyedrop or gel such as trifluridine or ganciclovir . Acyclovir , another antiviral drug, can be taken by mouth. Treatment should be started as soon as possible. Infections that cause deep inflammation may require use of corticosteroid drops and drops that dilate the eye, such as atropine or scopolamine . Occasionally, to help speed healing, an ophthalmologist may gently rub the surface of the cornea to remove infectious virus and viral antigens that contribute to the keratitis. Since most cases of HSV epithelial keratitis resolve spontaneously within three weeks, the rationale for treatment is to minimize damage and scarring. Antiviral therapy, topical or oral, is an effective treatment of ophthalmic herpes infections. Patients with frequent recurrences of ocular HSV may be placed on a long-term regimen of oral antiviral medication at a maintenance dose to reduce this frequency.

Emerging Therapy: Crispr/cas9 System
Currently, the only approved antiviral treatments for HSV-1 infections involve nucleoside analogs which inhibit the replication of viral DNA . Corticosteroids can be used to reduce inflammation, but they do not directly inhibit the viral infection . During a latent HSV-1 infection, such treatments are ineffective as the virus is not actively replicating its genome with its DNA polymerase. The efficacy of the even the newer treatments mentioned above to treat a latent HSV-1 infection has also not been demonstrated. This niche of treating a latent HSV-1 infection may be fulfilled by clustered regularly interspaced short palindromic repeats /Cas9 technology.
In another study published in 2016, van Diemen et al. significantly inhibited HSV-1 replication after transfecting Vero cells with one of twelve gRNAs with greater effects observed for the inhibition of essential genes . Transfecting cells with 2 gRNAs further impeded viral replication, and if two gRNAs targeting essential genes were used, viral replication was abolished: A six-log reduction in viral progeny was observed . With regards to latent HSV-1 infections, the CRISPR/Cas9 system could not efficiently edit quiescent HSV-1 genomes . However, it was effective in causing mutations in newly made viral DNA from reactivated HSV-1, further supporting the ability of CRISPR/Cas9 to confer prophylactic benefits to cells .

So What Is Eye Herpes
Eye herpes, or HSV keratitis, is a common eye infection typically caused by type 1 herpes simplex virus , the same virus that causes cold sores around the mouth and lips. However, eye herpes can also be caused by the HSV-2 and herpes zoster viruses. Eye herpes affects approximately 1.5 million people around the world each year, and is one of the most common causes of infectious blindness in the USA and Canada.
People typically contract eye herpes by touching a cold sore and then touching the eyes with their contaminated fingers. Once contracted, the virus stays in the body for life.
Ocular herpes tends to infect the cornea, causing inflammation, eye redness, tearing, and in rare cases vision loss. Many people with eye herpes may not even know they have it, as it can remain dormant within the nervous system without causing any flare-ups. It’s not uncommon for HSV to reactivate months or even years after initially contracting the virus. Flare-ups usually resolve on their own within 12 weeks, and many of them will recur within 10 years.
Herpetic eye infections can be confused with other types of pink eye, such as bacterial or other viral infections. Instead of self-treating an eye infection with antibiotics you have at home, get it examined by an eye doctor or physician, who can prescribe the right medication. Eye herpes won’t improve with antibiotics unless an antiviral is also used.
