The ability of each eye to demonstrate a full range of motion in all directions (up, down, left, right) when tested individually under monocular viewing conditions. Evaluating ductions assesses the mechanical integrity and function of the extraocular muscles and cranial nerves controlling eye movements. Limitations in ductions can indicate muscle or nerve dysfunction, restrictive forces, or mechanical restrictions.
