Apparatus and methods for testing temporal resolution of vision in a human subject are disclosed in which a light source is repetitively energized to produce pairs of visual stimuli, and the time interval between two stimuli in each pair is varied so as to enable the assessment of the minimum interval for which the subject under test can discern the separate stimuli in the pair. Means are provided for fixating the center of the subject's visual field, and the position of the visual stimuli within the visual field is varied so as to enable a map to be drawn showing the variation of the subject's temporal resolution over his visual field. Temporal resolution measured in this way enables certain diseases to be diagnosed and distinguished.
