Definition
What nerve constricts the pupil, a movement known as Miosis; opposite, Mydriasis, is the dilation of the pupil; the ciliaris muscle contracts = accommodation.
The accommodation reflex is a reflex action of the eye, in response to focusing on a near object, then looking at distant object (and vice versa), comprising coordinated changes in vergence, lens shape and pupil size (accommodation). It is dependent on cranial nerve II (afferent limb of reflex), superior centres and cranial nerve III.The change in the shape of the lens is controlled by the cilliary muscles inside the eye. Changes in contraction of the ciliary muscles alter the focal distance of the eye, causing nearer or farther images to come into focus on the retina; this process is known as accommodation.[1] The reflex, controlled by the parasympathetic nervous system, involves three responses; pupil accommodation, lens accommodation, and convergence. |

|
Term
| Ask the patient to close their eyes. This leaves only two of the three systems remaining and if there is a vestibular disorder (labyrinthine) or a sensory disorder (proprioceptive dysfunction-dorsal column) the patient will become much more imbalanced. |
