Abstract
Ocular oscillations are of many types and usually reflect instability in one of the four major subclasses of eye movements: saccadic, pursuit, vestibular, or vergence. Since the systems that generate eye movements receive afferent (e.g. visual) and probably internal (‘efference copy’) feedback about their performance, one can analyse ocular motor performance using control systems theory (Robinson, 1981b). Feedback systems are susceptible to instability and oscillations. An increase in the gain (output/input ratio) or in the phase (or delay from input to output) may lead to instability. Recent experimental research has emphasised several physiological mechanisms that may underlie some types of instability and oscillation that occur in the ocular motor system.
