1).If no response from patient, stimulus interval default as 1000ms;
2).If patient response，the system will adjust the stimulus interval according to the weighted
average of last 5 patient respond speed，if patient respond slow then the stimulus interval will be
automatically prolong. If patient respond fast then the stimulus interval will shorten automatically
2.1.6 The distance between patient eye and the fixation：300 mm±10 mm。
2.1.7 The instrument have head location device, and configure movable chinrest and forehead rest,
their travel distance from left-right ≥30 mm，and the chin rest of chinrest from up-down ≥50
mm.
2.1.8 This equipment configure auto calibration function for stimulus intensity, device will calibrate
the background intensity and stimulus intensity automatically while operator power on the equipment.
2.1.9 Input power：300VA。
2.2 Flowchart
2.3 Working principle
The working principle of the perimeter is to examining the sensitivity of the human eye to light
stimulus which enable to check the lesions of optic nerve, retina, visual pathway etc. The ambient
light enter into retina by refraction system, then the retinal generate the photochemical reactions
which produce the bioelectrical which transmitted through the visual pathway to visual cortex, so that
the brain could generate the vision through a comprehensive analysis. Any part of the distribution and
the trend of the nerve fibers from the retina to the visual cortex could indicate the lesions which
happened on the visual pathway. The lesion part, the characteristic and prognosis can be all analyzed
by applying the clinic test results according to its visual transform.
