During World Glaucoma Week, we get a chance to highlight that everyone should have regular eye tests and health checks in order to detect/ prevent glaucoma as early as possible to help treat glaucoma, prevent the loss of vision and eliminate glaucoma blindness. In 2020 it marked a milestone year as it had been a decade of raising awareness on the symptoms of glaucoma through the World Glaucoma Week campaign so to support this initiative Opticall have put together some insights into this eye condition.
To find out more about this eye condition we asked our Lead Optometrist (and one of our home visit opticians) Satish Pancholi about the second leading cause of blindness in the world that affects an estimated 78 million individuals in the world – glaucoma.
Glaucoma is the name for a group of eye conditions that cause sight loss because of damage to the optic nerve – the nerve that connects the eyes to the brain. There are different types of glaucoma and increased pressure in your eyes and age are important risk factors. Unfortunately, damage to the optic nerve can’t be reversed. Around 60 million people are currently living with glaucoma.
Glaucoma damage can be prevented if detected and treated early. However, sight loss is irreversible. This is why it is so important to have regular eye examinations as our Opticians test for glaucoma as part of the routine eye test, so a glaucoma treatment plan can be set up.
Glaucoma is often (but not always) linked to high eye pressure. Our eyes contain fluid called aqueous humour, which helps them hold their shape. When this fluid no longer drains away fast enough, eye pressure can rise – but glaucoma can occur in people with normal eye pressure too.
Why some people develop glaucoma and others don’t isn’t fully understood yet, but a number of causes have been recognised. Age is the biggest risk factor with almost 10% of people aged 75 and over having the most common type of glaucoma. People with a close relative, such as a parent, with the condition may also be at higher risk, and ethnicity (African, Caribbean or Asian origin) is a factor for certain types of glaucoma too.
Glaucoma tends to develop slowly and often doesn’t cause noticeable symptoms until damage has already occurred. Sometimes people experience acute glaucoma which causes a sudden onset of severe eye pain and blurred vision.
When glaucoma does cause symptoms, these might include:
Glaucoma is usually diagnosed following routine eye tests. Tests for glaucoma often start with an eye pressure test. An optometrist will also examine the front part of the eye, to see whether they can spot any issues with fluid drainage, such as a blockage. If glaucoma is suspected, patients will be referred to a specialist to confirm the diagnosis and assess any damage that’s already occurred. This is why you should book an eye test regularly.
Once diagnosed the treatment to slow the advancement of this condition can commence (dependent on the specific type and progression) and that can involve a number of treatment options such as prescription eye drops, laser therapy, surgery or special therapies. There are new treatments being researched all the time too so these options will change/develop with time.
