In this video, you will learn how to perform the saccade test, which assesses the patient's ability to move their eyes rapidly between focal points. Watch...
The saccade test (a test of the central vestibular system) assesses the patient's ability to move their eyes rapidly, from one focal point to another. As this is a random saccade test, the eye movements are reflexive rather than voluntary.
You can test in both horizontal and vertical directions. Abnormalities can include:1) velocity of eye movements, either too slow or too fast2) accuracy of eye movements, either overshooting or undershooting3) latency of eye movements (reaction time), usually this is only a long latency as abnormally short latencies are most likely due to the patient anticipating the movement
The results can provide very specific site of lesion information. This video shows a horizontal saccade test being performed on a patient.
