Recognising symptoms of chronic glaucoma

Glaucoma is problematic as it is not painful and there are no symptoms until it is really advanced.
 
Glaucoma usually starts by affecting your side vision (peripheral vision). You often don’t notice this as your brain can compensate for a large amount of this part of your vision being affected. 

Considerable damage can be done to your side vision before you realise it, so it is important to have regular eye checks that include checks for glaucoma.

If glaucoma isn't caught and treated early - then it can go on to cause fairly serious 'tunnel vision'. Eventually, without treatment, it will also affect your central vision.
