This blank area, if the glaucoma is untreated, spreads both outwards and inwards. In time even this sight would be lost. As glaucoma becomes much more common over the age of forty you should have eye tests at least every two years and ask for all three glaucoma tests. This has been shown to be much more effective in detecting glaucoma than just having one or two. The main treatment for chronic glaucoma aims to reduce the pressure in your eye.
Some treatments also aim to improve the blood supply of the optic nerve.
You will need to go to hospital for treatment and have regular check-ups afterwards. Treatment to lower the pressure is usually started with eyedrops. These act by reducing the amount of fluid produced in the eye or by opening up the drainage channels so that excess liquid can drain away. If this does not help, your specialist may suggest either laser treatment or an operation called a trabeculectomy to improve the drainage of fluids from your eye. Your specialist will discuss with you which is the best method in your particular case.
