In brief: Restricted field

Tunnel vision is when the vision outside the central axis is impaired or lost.
It is typical for some inherited conditions and occurs in advanced diseases like glaucoma and diabetes. It is quite handicapping even if the central vision is fine and if less than about 10 degrees may require a seeing eye dog.
