Watch Out For These Early Warning Signs Of Glaucoma

Tunnel Vision

Tunnel vision can quite literally look like the individual is seeing through a tunnel. It typically occurs during late-stage primary open-angle glaucoma and develops as a gradual narrowing of the person’s peripheral vision. Tunnel vision interrupts the individual’s ability to see the edges or corners of whatever they are looking at directly. Unfortunately, many individuals do not realize their sight is becoming limited or narrowing until later stages of the disease. If individuals notice any changes in their peripheral vision, even small ones, they should see an eye doctor immediately.
