Pursuits

Choose how to set up this exercise.

Mal de Débarquement Syndrome

An optokinetic head-roll exercise. You will watch full-field stripes that move opposite to your sway while gently moving your head in time with a slow beat.

Notice the main way your rocking or swaying pulls you and pick it below. The stripes then move in the opposite direction. If you can't tell, pick one to start — if there's no improvement after about five days, try the opposite.

Hold the screen close so the stripes fill your vision. These keep the stripes at 20°/second for your setup.

Saccades

Choose how to set up this exercise.

FN protocol

Saccades with a return pursuit. Adjust the settings, then start.

Saccade Latency Training

Targets appear randomly across the screen after a 200ms gap. Adjust how many land on the left versus the right.

All leftAll right

Eye Muscle Training

Check the Left and/or Right side for each muscle to train; each adds directional saccades then ramping pursuits. Reorder the selected list with the arrows.

Oculomotor Screen

A webcam-based screening measurement of saccades, smooth pursuit, optokinetic response and gaze stabilisation. Takes about 8–10 minutes.

Screening measurement — not a diagnostic test. Values are obtained with a consumer webcam sampling at roughly 30–60 frames per second. They are not equivalent to, and must not be compared against, videonystagmography (VNG), video head impulse testing (vHIT) or infrared eye tracking, which sample at 220–1000 Hz. Interpretation requires a qualified clinician. No published normal/abnormal threshold has been validated against this measurement method.
Privacy. All video is processed on this device only. No image or video ever leaves this computer and none is recorded or saved. Only the derived numeric measurements are stored.
Before you begin
  • Sit so your whole face is lit from the front — avoid a bright window behind you.
  • Remove glasses if the lenses reflect; contact lenses are fine.
  • Keep your head still for the first three tests. The last test asks you to turn your head.
  • Stop at any time with the Stop button if you feel unwell.
