In the UK, about 1 in 50 people aged over 40 has glaucoma. Centre for Sight surgeons also treat Glaucoma.
Glaucoma is the name given to a group of eye conditions which causes optic nerve damage and in turn can affect vision. Glaucoma damages the optic nerve at the point where it leaves the eye.
Glaucoma damage may be caused by raised eye pressure or a weakness in the structure surrounding in the optic nerve. Our eye pressures may be within normal limits but damage occurs because there is a weakness in the optic nerve which in turn affects blood flow to the nerve. NOTE: Eye pressure is not connected to your blood pressure.
