Detailed explanation-1: -To test for this disorder, ask the patient to sit upright and cover one of their eyes. The patient should then look directly at the light from the penlight. Observe the eye and note if it moves (medially, laterally, superiorly, or inferiorly) to focus. If it does, then the patient has strabismus in that eye.
Detailed explanation-2: -The trochlear nerve is one of 12 sets of cranial nerves. It enables movement in the eye’s superior oblique muscle. This makes it possible to look down. The nerve also enables you to move your eyes toward your nose or away from it.
Detailed explanation-3: -The diagnosis of unilateral trochlear nerve palsy is based on acute onset vertical deviation which increases in contralateral side gaze, down gaze and ipsilateral head-tilt together with excyclodeviation which also increases in both down gaze and ipsilateral head-tilt.
