Chronic open-angle glaucoma is a painless condition which causes damage to the optic nerve at the back of your eye and can affect your vision. The person affected is not aware they have it: open-angle glaucoma is detected by an optician or eye doctor. It is usually caused by an increase in pressure within your eye. If open-angle glaucoma is not treated, glaucoma can lead to visual loss at the edge of your vision and even to total loss of vision, although this is rare in high-income countries. Treatment can slow down glaucoma and help to prevent this. All adults aged over 35-40 should have a regular eye check which includes measurement of their eye pressure, although chronic open-angle glaucoma is more likely to affect people over the age of 60.
