Humphrey Visual Field Analyzer

A visual field test is performed to detect diminished or missing areas of vision in the central and peripheral (side) vision.

A visual field test detects those areas of your vision which may be affected by various medical conditions such as glaucoma, strokes and brain tumors or medications and injuries to the eye or brain.  The test may also be required by the DMV in order to keep or obtain a drivers license. Visual field testing is an important tool in the diagnosis and management of many conditions and diseases, such as glaucoma and stroke. It is used to determine if an area of vision has been affected, to evaluate the severity and to monitor progression of the disease or condition. 

The test is painless and generally does not require dilation drops. The length of testing is dependent on the test ordered.  Your doctor will discuss the reason for the test and what to expect.
