Glaucoma - FAQs
What is it?
Glaucoma is a disease in which the pressure within the eye gets too high. This pressure damages the Optic nerve at the back of the eye and causes tunnel vision if left untreated.
I am taking medication for blood pressure, will this help keep the eye pressure ok?
No. The pressure within the eye is not the same as blood pressure and cannot be treated in the same way.
How will I know if the pressure is too high?
During routine eye examinations, the pressure of the eye is measured. We usually use a machine that takes a reading by blowing a “puff of air” into the eye. From this we can tell if the pressures are within normal limits. It is not common for the patient to notice the pressures have increased.

Does the “Puff of air” hurt?
No! It makes most people jump which is not particularly pleasant, but it certainly isn't painful.
What happens if the pressure reading is high?
The Optometrist will look at whether there are any other factors contributing to the raised pressure, check the Optic nerve to see if any damage has occurred and do a visual field test to check to see if any blind spots are forming. If necessary a referral is made to the local hospital eye department for further investigations.
How do they treat Glaucoma?
The aim of the treatment is to reduce the pressure. This is commonly done by using a drop which is put into the eye on a daily basis. In some cases a small operation is required to reduce the pressure.
Does it run in families?
Yes! Your risk of Glaucoma increases if a direct member of the family has the disease. The NHS will pay for your eye examination if you are over forty and you are the child, sibling, or parent of a Glaucoma patient.
Can I do anything to prevent me from getting it?
Regular eye examinations are the key. An adult with no other eye problems should be having a full eye examination every 2 years.
