Patient eye response to a Smooth Pursuit Horizontal test. Smooth Pursuit tests are also referred to as Oscillating Tracking Tests. These ocular motor tests task a patient with tracking a dot moving with a sinusoidal motion profile. The moving dot is projected by the Pursuit TrackerTM laser target generator mounted on top of the I-Portal® NOTC patient chair.
Smooth Pursuit is a fundamental ocular motor test and is commonly included in all NKI test protocols. Tests are often run multiple times at gradually increasing frequencies, both horizontally and vertically. During the test, the saccadic movements of the patient's eyes are measured and the gain and phase of the eye movements are analyzed relative to the corresponding time position of the stimulus.
