Visual Field Analyzer

The visual field test is a subjective measure of central and peripheral vision, or “side vision”.   Visual field tests are used to detect blind spots (scotomas), which could be a sign of eye diseases.  The size and shape of a scotoma offer important clues about the presence and severity of diseases of the eye, optic nerve and visual structures in the brain.  Many eye and brain disorders can cause peripheral vision loss and other visual field abnormalities.
