Are you, or anyone you know, impacted by poor vision? It’s more common than you think.

It’s National Glaucoma Awareness Week. Running from June 4 to 10, 2018, it aims to raise awareness of the disease, which can lead to irreparable loss of vision.

We’ve put together 10 facts about the condition:

Glaucoma affects about 600,000 people in the UK – but half of them have not been diagnosed. Up to 67 million people worldwide live with the disease.

The condition results in the loss of peripheral vision but can progress to central vision as the damage to the optic nerve worsens.

The damage to the nerve is caused by a build-up of pressure within the eye.

Glaucoma has no discernible symptoms to begin with. But it can be detected by routine eye checks every two years.

That warm puff of air into your eye during your eye test is one of the checks for the disease.

Some people are at more risk than others. It’s more common in the over-60s and people with a family history of the disease.

It’s also more common in people of African, Caribbean or Asian origin.

There is no cure but treatment can slow its progress.

Any lost vision cannot be restored, but further deterioration can be prevented.

Treatment can range from eye drops to laser treatment or surgery, depending on the symptoms and type of glaucoma sufferers have. Surgery is only used if eye drops and laser treatment prove ineffective.
