Final answer:
To distinguish between Ocular and Congenital Torticollis, coordinated eye movement tests and reflex examinations are used to evaluate the function of extraocular muscles, the nerves controlling them, and the associated reflexes.
Step-by-step explanation:
To differentiate between Ocular Torticollis and Congenital Torticollis, specific eye movement tests can be performed. These tests observe the coordinated actions of extraocular muscles and the nerves that control them. By having a patient track a visual stimulus like the tip of a pen through their visual field, medical professionals look for conjugate movements that indicate healthy function of the oculomotor, trochlear, and abducens nerves, as well as the medial longitudinal fasciculus (MLF). An absence of coordinated movement, or diplopia, suggests issues within these systems and can help discern between ocular and congenital forms of torticollis. Various reflexes such as the accommodation-convergence reflex and pupillary light reflex are also examined to assess eye functional integrity.
