How Glaucoma May Affect Vision

Normal Vision

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 Glaucoma

Early symptoms may include a gradual and often imperceptible failing of side (peripheral) vision.

Advanced Glaucoma

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.
