Humphrey Visual Field Analyzer

A visual field test measures how much peripheral or side vision you have. This test will detect any loss of peripheral vision and provide a detailed map of the extent and depth of that loss, which is helpful in diagnosing diseases such as glaucoma, macular degeneration, and in monitoring for drug toxicity caused by some common medications. It is also performed when a patient has unexplained visual disturbances or vision loss. In these cases, it may uncover a pituitary tumor or other disease process requiring prompt attention.
