Design outcomes

Primary

Measure	Time frame
Our study will make measurements of motion perception thresholds for over a range of different oscillation frequencies and luminances. The motion perception threshold is the minimum oscillation amplitude at which motion is perceivable. This will be determined for each oscillation frequency and luminance. Motion perception thresholds can then be compared between the healthy control group and glaucoma patients.	—
