Visual Field Test
Clinically, we usually carry out the monocular visual field test on the two eyes separately so that a comparison between them can be conducted. Sometimes, a binocular visual field test may be performed in situations such as tests for drivers. The fixation status of the tested eye should be emphasized repeatedly, whatever the test type. Light stimuli with certain intensity are presented dynamically or statically on the background with uniform illumination under the fixation status to determine the differential light threshold or the area where it is visible [1–4].
