Glaucoma is a disease that causes progressive vision loss due to damage to the optic nerve (the cable that carries information from the eye to the brain). In an eye with glaucoma, the optic nerve is sensitive to the pressure in the eye, which leads to the fibres in the nerve being damaged.
What does it do?
This nerve damage causes peripheral vision to be lost, eventually leading to tunnel vision then complete blindness if left untreated.
What is the treatment?
Treatment aims to lower the pressure in the eye, usually using eye drops or surgery. If glaucoma is caught and treated early, blindness is preventable. Unfortunately, in the early stages people usually have no symptoms because our brains are so good at “filling in” any missing vision, and it is usually painless.
How can I prevent it?
Having regular eye exams is the best way to find glaucoma and treat it early, before vision loss starts. An eye exam every 2 years is recommended from age 40, or sooner if you have a family or personal history of eye problems. At Visique Rose Optometrists we have all the equipment needed to diagnose and monitor glaucoma, such as OCT, pachymetry and visual field machines.
