Glaucoma

What is Glaucoma?

Glaucoma is not a single disease. It is caused by a group of eye conditions that damage the optic nerve. The optic nerve contains over one million nerve fibres and carries visual information from the eye to the brain. As Glaucoma damages these fibres, vision is lost.

Do you think Glaucoma is having high eye pressure?

Latest research reveals that Glaucoma is much more than just having high IOP. (Intraocular Pressure). You can have high pressure and NOT have Glaucoma. Additionally, you can have normal pressure and suffer from Glaucoma (Low Tension Glaucoma)

Ninety percent of people with elevated pressure do not have Glaucoma, and up to one third of those with Glaucoma have a “normal” eye pressure.

Why corneal thickness?

The largest Ocular Hypertension Study (High eye pressure) showed that a person at risk of Glaucoma is 20 TIMES MORE LIKELY to develop Glaucoma if they have a thin cornea than if they have a thick cornea. We now use a Glaucoma risk assessment calculator from this research which calculates the % risk of Ocular hypertension turning into Glaucoma.
