Question

NIH - What are you testing for asked month and his/her age, asked to open and close eyes and then to grip and release non-paretic hand?

Answer 1

Testing eye movement involves having the patient track the tip of a pen passed through their visual field. Failure of one eye to abduct while the other adducts is called internuclear ophthalmoplegia.

Step-by-step explanation:

Testing eye movement is simply a matter of having the patient track the tip of a pen as it is passed through the visual field. The patient is asked not to move the eyes while the examiner moves the stimulus into the peripheral visual field. The examiner is checking for conjugate movements, representing proper function of the related nuclei and the MLF. Failure of one eye to abduct while the other adducts in a horizontal movement is referred to as internuclear ophthalmoplegia.
