Around 25,200 Greater Manchester residents are in danger of going blind from glaucoma – one of the largest causes of blindness in the world – due to its gradual onset. That is why this Glaucoma Awareness Week (June 17-23), Specsavers stores throughout Greater Manchester are highlighting the importance of looking after our eyes.
Glaucoma usually occurs when naturally-occurring fluid inside the eye does not drain properly, leading to a build-up of pressure. This can then cause damage to the optic nerve and nerve fibres from the retina, in most cases without any symptoms. While the condition cannot be reversed, it can be managed – but early detection is key.
More than 64 million people around the world live with glaucoma – but as long as you are sensible you don’t need to let it take over your life.
Symptoms can vary depending on what type of glaucoma you have – either chronic or acute. Many don’t realise there is anything wrong with their sight which is why regular visits to the optician are essential.
Steven Dare, store director at Specsavers Sale, Altrincham & Urmston, says: ‘With the most common form of glaucoma, visual loss is initially very subtle, affecting mainly the peripheral vision rather than central, which can make it harder to notice. Most people are not even aware there is any visual loss because of the way the eyes’ visual fields overlap to compensate for one another.
‘Some forms of glaucoma are more rapid with a sudden painful build-up of pressure in the eye which produces blurred vision and haloes around lights, but they are less common.’
It is vitally important people attend regular check-ups at their optician to check for any signs. At your appointment they will they will test your eye pressure as high pressure is a common sign of glaucoma, and they’ll do a visual field test which can detect any subtle blind spots you may not be aware of, which can also be an indicator of the condition.
Karen Osborn Chief Executive of the International Glaucoma Association (IGA) says: ‘We regularly hear from people who have permanently lost sight to glaucoma because of late diagnosis. People are often angry and upset to learn that simple regular visits to their local high street optometrist could have detected the condition. The earlier treatment starts, the more likely that someone will retain useful sight for life, so it’s great that so many Specsavers stores are on board with Awareness Week.’
For those who already have glaucoma, digital retinal photography (DRP) is used to asses and keep check of damage to the optic nerve and nerve fibres from the retina from pressure build up.
Specsavers stores in Greater Manchester include Manchester Arndale, Manchester Fort, Eccles, Harpurhey, Openshaw, Rochdale, Bury, Royton, Oldham, Ashton-under-Lyne, Stretford, Sale, Altrincham, Urmston, Fallowfield, Wythenshawe, Swinton and Salford.
"The good news is glaucoma can generally be treated effectively if detected early, and in most cases, daily eye drops are used."
