Humphrey Visual Fields

What is this test screening for?

A Full Threshold Visual Field Analyzer is most commonly used to monitor or diagnose glaucoma and neurological diseases. Visual field loss due to retinal disease could be caused by anemia, blood vessel occlusion, diabetes, hypertension, retinal detachment, retinitis pigmentosa, macular degeneration, glaucoma and many more.

How this is administered?

The patient sits comfortable in front of the Oculus, resting their chin in the chin rest.  Using one eye at a time, the patient will focus through the lens at four red dots and press a hand-held response button when the dots appear.  The test takes up to 8 minutes per eye, with the total exam lasting approximately 15 minutes.
