Applied Physiology of Eye Movements

Eye movements are complex, requiring the extraocular musclesExtraocular muscles to work according to the physiological laws of Hering and Sherington. These govern contraction and relaxation of muscles in groups in a coordinated manner to achieve binocular movements or versionsVersions. Uniocular movements are called ductionsDuctions, conjugateConjugate movements are in the same direction and disconjugateDisconjugate movements involve either a convergence or divergence of the eyes.
