Glaucoma damage may be caused by raised eye pressure or a weakness in your optic nerve. Or you may have an eye pressure within normal limits but the damage occurs because there is a weakness in your optic nerve. In most cases, high pressure and weakness in the optic nerve are both involved to a varying extent. (Eye pressure is not connected to your blood pressure.)
