peripheral vision

does the Humphrey exam test your full peripheral vision 90 degrees or somewhere around 30 degrees?   My employer has kept me off work because my humphrey test didnt show I met the 90 degree requirement bua a confrontational exam I took showed 90 degrees

Almost no modern visual field equipment goes much past 60 degrees with accuracy.  The old Goldmann perimeter is the closest you can get to 90 degrees but these machines are becoming extinct.  If your employer is insisting that you have a visual field test with a "machine" out to 90 degrees, probably your best bet is to call your eye doc's office back and ask them to check their Humphrey software for the largest visual field setting possible.  Since we so rarely use these larger field settings, sometimes they are in the software but no one knows about it.  If this still isn't good enough, start calling offices and asking specifically if they own the Goldmann (two n's) machine.  Good luck.
