MarkH1982 - Your Question:I suffered massive trauma to the left eye nearly 2 years ago now. You should seek independent professional advice before acting upon any information on the EyeHelp website. They affect around 1 to 2 people in every 1,000 in the UK.When to see your GPIt's important to see your GP as soon as possible if you have symptoms of a herpes simplex eye infection. Herpes simplex infection in the outermost layer of cells is usually referred to as epithelial keratitis. This is really a question you should be asking the consultant who would perform the surgery! Keratitis is responsible for causing corneal ulcer, an open sore or erosion in the outer layer of cornea.
Herpes simplex keratitis infects the superficial layer of the cornea with diffuse branching or punctuates lesions on the epithelium which excludes the stroma. They may also test your vision using a chart.Eye specialistIf your GP thinks you may have a herpes simplex eye infection, they will send you to an eye specialist (ophthalmologist), who should see you as quickly as possible.
The two types of Herpes simplex virus have different pathogenic effects; Herpes simplex type 1 causes cold sores.
The application of topical glucocoticoid to the infected eye can worsen the infection and lead to the inclusion of the stromal structure.
This is because herpes simplex infection is difficult to diagnose without specialist knowledge and equipment.
The virus stays in the body, which means once you have had a cold sore, you are liable to get one again in the future.Triggers that release the virus from the nerve back into the skin include stress, being run down and being out in the cold. The lower temperatures causes trauma to the skin, which is enough to set the virus off again.
The first time you're infected is known as the "primary infection", which doesn't cause any symptoms. This virus can also do a similar thing in the eye and is the main cause of herpetic eye infections. The human body becomes resistant to them quite quickly in most cases of herpes eye infections.


Type 1 virus is the usual cause of cold sores around the mouth, and herpes simplex infection in the eye.
The virus stays inactive in the root of a facial nerve.Triggers of a herpes simplex eye infectionThe virus can be reactivated spontaneously or by certain trigger factors. Herpes type 2 is the virus that causes genital herpes a€“ it rarely infects the eye or causes cold sores.Herpes Simplex Infections in the EyeWhen this virus infects the eye, it only multiplies in the surface layer of cells, in the cornea. To try to reduce the symptoms and discomfort, epithelial keratitis can be treated with eye drops containing acyclovir or ganciclovir.
This is the see-through window that allows light to pass easily through the pupil and to the retina, to allow images to be processed by the brain. These antiviral agents prevent the virus from multiplying quite so efficiently within the eye tissue, and give the immune system a chance to beat the virus more quickly.If the infection has spread to the deeper layers of the eye, it may be necessary to add in some steroid eye drops to the treatment. When the cornea is infected, it leads to a condition known as keratitis, which can be painful. Treating the eye with steroids is a delicate business and it is up to the judgement of an eye specialist to decide whether this treatment will be beneficial or not.Preventing Corneal ScarringAlthough eye infections due to Herpes simplex clear up fairly quickly, repeated infections can cause the cornea to become scarred, which can affect vision.
It's important to follow the advice you are given and take any prescribed treatment carefully and for the complete course.TabletsIn some cases, antiviral tablets may be prescribed after treatment to stop the infection returning.
It is important that each new eye infection is treated very promptly to minimise the impact on the cornea.
In people whose infections happen often and are very severe, a corneal transplant may be necessary to allow them to keep their eyesight.
It is also common to feel uncomfortable in bright light a€“ a condition known medically as photophobia. Having a Herpes eye infection usually makes your vision very blurred a€“ and it can cause the eye to feel painful, causing a generalised headache. It is commonly passed on by close contact such as kisses from a family member who has a cold sore.) In many people the primary infection does not cause any symptoms, although in some cases symptoms do occur. A minor and temporary inflammation of the conjunctiva (conjunctivitis) or eyelids (blepharitis) may occur with active infection, often at the same time as the cornea is infected. Often people who get active eye infection will have had previous cold sores during their lifetime.
They may also put some stain on the front of your eye to show up any irregular areas on the cornea.


If your doctor suspects a herpes eye infection you will usually be referred urgently to an eye specialist.
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).
These do not kill the virus but stop it from multiplying further until the infection clears. You are likely to be kept under review, until the infection clears, to check that the cornea does not become infected.
Note: if you have herpes simplex eye infection, you should stop wearing any contact lens until 24 hours after your symptoms and the infection have completely gone away. 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.
If recurrences are frequent or severe, then 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. It is also possible that active infection may be triggered if you are run down or unwell for another reason. Some women find that they get recurrences around the time of their period but again there is limited evidence to support this. However, severe and recurrent herpes simplex eye infections may lead to serious scarring, impaired vision and even blindness in some cases.
