NBEO Ocular Motility Practice Test

The term that covers abnormalities across fixation, saccades, and smooth pursuit is oculomotor dysfunction. This label reflects problems in the neural systems that control eye movements—the stability of gaze during fixation, the rapid, goal-directed jumps of the eyes (saccades), and the ability to smoothly track moving targets (pursuits). When these systems are not functioning properly, you can see a range of issues from unstable fixation to inaccurate saccades or impaired tracking, all under the umbrella of oculomotor dysfunction.

Other terms describe related but narrower or different concepts: a visual attention deficit centers on processing and attention rather than motor control of the eyes; ocular motor restriction implies a mechanical limitation in how far the eyes can move, not the broader spectrum of movement abnormalities; oculopathy is a general eye disease label that doesn’t specify motor control issues. The broad, precise umbrella for these eye movement problems is oculomotor dysfunction.
