This is an example of normal vision. This is also an example of how someone sees during the beginning stages of open-angle glaucoma. Because there are no symptoms initially, regular eye examinations are very important.
Early symptoms may include a gradual and often imperceptible failing of side (peripheral) vision.
As glaucoma progresses, the center of vision may still be clear, however peripheral vision begins to fail.
During the advanced stages of glaucoma, only a small central area of vision remains. Eventually, damage to the optic nerve will result in total blindness.
