An objective or subjective assessment of the eye movement system, typically evaluating two functions: Smooth Pursuit (following a slow, moving target) and Saccades (rapid, accurate jumps between two fixed targets).
read more about visual tracking test ...Used to diagnose oculomotor dysfunction, which can cause reading difficulties (losing place, skipping lines) or neurological control problems (e.g., tracking a light with the eyes).
Clinical tools include the DEM test (Developmental Eye Movement test) or objective eye-tracking systems that plot the speed and accuracy of the eye movements.
Poor saccadic accuracy means the eyes overshoot or undershoot the next word, requiring a corrective eye movement (regression), which slows reading.
Smooth pursuit is slow, continuous tracking (e.g., watching a bird fly). Saccades are rapid, jump-like movements (e.g., reading word by word).
Yes. Oculomotor therapy, often using lights or computer targets, is highly effective at improving the speed and accuracy of both pursuit and saccadic movements.
A separate test that assesses the eye's ability to turn inward (converge) to maintain single vision on a near target.
