Pressure checked?

MOT your eyes today and save sight loss from glaucoma


The International Glaucoma Association is focusing on the importance of eye pressure in detecting glaucoma as part of National Glaucoma Awareness Week (12 – 18 June 2017).

People regularly check the pressure in car tyres, the boiler and even check their blood pressure regularly but who thinks about eye pressure?

It is the pressure in the eye which keeps it inflated. If it is too high it can lead to irreversible damage to the optic nerve leading to loss of vision. It is estimated that there are 64 million people with glaucoma worldwide and 600,000 in the UK, with half undetected.

“People have such a limited knowledge about the health of their eyes. All too often we hear that people do not have an eye health check until they realise that something is wrong with their vision. This is too late for glaucoma as a significant amount of vision will be lost and it can never be recovered,” comments Karen Osborn, Chief Executive of the International Glaucoma Association.


The tests are quick, simple and convenient. A visit to the local high-street optician is all that is needed to see if you are at risk of glaucoma. There are three simple tests which include:

1. Looking at the appearance of the main nerve in the eye, called the optic nerve (ophthalmoscopy)
2. Measuring the pressure in the eye, often referred to as the air puff test, (tonometry)
3. Checking the field of vision (perimetry). In Scotland there is a fourth test called pachymetry which measures the corneal thickness.

“Our helpline takes calls from people who are shocked to realise that had they had an eye health check earlier, then they may not have lost a significant portion of their sight. Glaucoma is known as the silent thief of sight for a good reason, as the brain fills in the missing parts of vision and it isn’t until there is significant sight loss that a person thinks to visit an optometrist who can help to detect what is happening”.
The IGA believes that everyone should have an eye health check every two years and more frequently if advised by a health professional.
