World Glaucoma Week
11 Mar 2018
What is World Glaucoma Week?
World Glaucoma week will be taking place from the 11th-17th March 2018 with the primary focus of raising awareness of Glaucoma a very common eye disease. The purpose is to bring communities from around the world together to help make a difference and spread the word of the importance of eye health and preventing Glaucoma.
A wide range of publicity-attracting activities around the world involve ophthalmologists, optometrists and other eye care workers in hospitals, universities, clinics, private practices include many private individuals, especially those with glaucoma or with family members with glaucoma. Glaucoma societies and glaucoma patient associations all participate.
As a major collaboration between the World Glaucoma Association and the World Glaucoma Patient Association, this series of activities globally alerts people to have regular eye (and optic nerve) checks to detect glaucoma earlier, thus contributing to sight preservation.

What is Glaucoma?
Glaucoma is a common eye condition where the optic nerve, which connects the eye to the brain, becomes damaged. Glaucoma is a disease of the eye in which fluid pressure within the eye rises; if left untreated, the patient may lose vision and even become blind.
Glaucoma is the name for a group of eye conditions where your optic nerve (the nerve that connects your eye to your brain) is damaged and your vision becomes worse. Glaucoma can affect both of your eyes, but one eye may be affected more than the other. Vision that has been lost can’t be restored but if you have treatment early, it can prevent further sight loss.
If you have glaucoma, your optic nerve (the nerve that connects your eye to your brain) is damaged at the point where it leaves your eye. Often, this damage is the result of an increase in pressure in your eye. This may happen when fluid (the aqueous humour) in the front part of your eye (the anterior chamber) doesn’t drain away properly.
Usually, the amount of fluid produced in your eye is balanced by the amount draining away, so the pressure in your eye stays the same. If you have a problem with draining away the fluid in the front of your eye, the pressure within your eye can become so high that your optic nerve is damaged. Because of this, you may begin to lose your sight.
Although raised pressure in your eye is the most common cause of glaucoma, the condition can also be caused by other things. For example, a weakness in your optic nerve. This can lead to damage even when the pressure in your eye appears to be normal.
What are the Risk Factors of Glaucoma?
• Increased eye pressure
• Family history of glaucoma
• Eye Injury
• Eye Conditions
• Eye Surgery
• Age- the older you are the increased risk i.e. over 50 years of age
• Ethnic background
• Conditions that affect or are related to blood flow i.e. migraines, low blood pressure, diabetes, hypertension
• Optic nerve damage
• Being short sighted
What are the Symptoms of Glaucoma?
• Intense eye pain
• A red eye
• A headache
• Tenderness around the eyes
• Seeing rings (halos) around lights
• Blurred vision
• Sudden onset of visual disturbance, often in low light
• Gradual loss of peripheral vision, usually in both eyes
How is Glaucoma Diagnosed?
• Glaucoma can usually be detected during a routine eye test at an optician, often before it causes any noticeable symptoms.
• The tests are carried out normally in the opticians by an optometrist.
• You should have a routine eye test at least every 2 years.
• Several quick and painless tests can be carried out to check for glaucoma, including vision tests, measurements of the pressure inside your eye.
• If test results suggest you have glaucoma, you should be referred to a specialist eye doctor (ophthalmologist) to discuss treatment.
• Eye Pressure Test- An eye pressure test uses an instrument called a tonometer to measure the pressure inside your eye.
• Gonioscopy- Gonioscopy is an examination to look at the front part of your eye the fluid filled space between the coloured part (iris) and the clear window on the front of the eye (cornea). This is where the fluid should drain out of your eye. A gonioscopy can help determine whether this area is open or closed, which can affect how fluid is drained out of your eye. This will tell your optometrist what type of glaucoma you have.
• Visual Field Test- A visual field test checks for missing areas of vision.
• Optic Nerve Assessment- The optic nerve connecting your eyes to the brain can become damaged in glaucoma, so an assessment may also be carried out to determine whether it is healthy.
• Referral to a specialist- Ophthalmologist will confirm your diagnosis of Glaucoma and determine how far the condition has developed, how much damage the Glaucoma has done to your eyes and what may have caused the Glaucoma.
