Movement of a limb towards the central line of the body, or of a digit towards the axis of a limb. Muscles that carry out this movement are often called adductors. (See also abduction.)
a condition, usually congenital, in which the tendon sheath of the superior oblique muscle of the *eye does not relax, thus limiting the elevation of the eye, especially in adduction. [H. W. Brown (20th century), US ophthalmologist]... brown’s syndrome
an abnormality of the eye muscles leading most commonly to restricted abduction (outward movement of the eye away from the midline) of one eye. On attempted adduction (inward movement of the eye towards the midline) of that same eye there is retraction of the eye into the orbit and narrowing of the opening between the eyelids. [A. Duane (1858–1926), US ophthalmologist]... duane’s syndrome
pl. n. movements of one eye, i.e. adduction (rotation towards the nose), abduction (rotation towards the temple), elevation, depression, intorsion, and extorsion.... ductions
