False negative	Ratio of not responding by presenting a 9 dB bright target to the determined threshold Included observation point unknown Monocular	Ratio of not responding by presenting a 9 dB bright target to the determined threshold All observation points known except for outermost circumference Binocular random conditions
Fixation loss	Percentage in response to stimulus to blind spots	Percentage in response to stimulus to blind spots
