What is glaucoma?

Glaucoma is a condition in which the nerve of sight, (the optic nerve) has become damaged. This is usually because of increased pressure within the eye. The damage is permanent and initially destroys the off centre part of your vision – your peripheral vision. Sight will continue to deteriorate and eventually, if the condition is not treated, blindness will result. Chronic glaucoma is the most common form of the condition and has no symptoms and causes no pain. This means that by the time you are able to notice a difference to your vision, some sight may already have been permanently lost.

How can glaucoma be detected?

Regular visits to an optometrist (optician) are essential to ensure there are no hidden problems such as glaucoma creeping up behind you. Ask your optician for all three glaucoma tests when you next have an eye health check. The three tests are Opthalmoscopy (viewing the optic disc with a special torch), Perimetry (assessing the field of vision) and Tonometry (measuring the eye pressure) – OPT. If your optometrist is not willing or is unable to perform all three tests, find an optometrist who will.
