A method of measuring retinal or visual pathway function comprises stimulating optokinetic nystagmus by presenting a visual stimulus to a patient; modifying a first parameter of the visual stimulus; modifying a second parameter of the visual stimulus; and using the modified visual stimulus to determine a threshold stimulus for optokinetic nystagmus; wherein the first and second parameters are selected from a group of parameters comprising a pattern for the visual stimulus, a width of the visual stimulus, a distance between the visual stimulus and the patient, a spatial frequency of the visual stimulus, a rate of change or temporal frequency of the test face of the visual stimulus, and a contrast between elements of the visual stimulus.
