Q:What are the causes of and treatments for glaucoma and does high blood pressure have an effect on high pressure in the eyes?
A:Glaucoma occurs when the pressure of the fluid in your eye becomes too high. Left untreated, this can cause blindness because of damage to the optic nerve. High pressure in your eye is different from high blood pressure. You can have high blood pressure and not get glaucoma. Left untreated, high blood pressure can damage blood vessels in the eye resulting in loss of vision.
