Visual Field

A visual field test is a way to measure your visual field. Your visual field is an indicator of how much you can see to each side while focusing your eyes on a central point (peripheral vision). The test maps central vision as well as peripheral (side) vision. 

The test is performed by an ophthalmologist and is used to detect areas of vision loss (blind spots) caused by a brain tumor, stroke, glaucoma, diabetes, hypertension, or head trauma. It can also be used to monitor the progression of previously known visual field loss.
