binocularity - 2023 ARCADIA

Question

The eyes are the windows to the soul, and to the pathologies of the nervous system. For 10 points each:

[10e] Description acceptable. Visualize deficits of this nature localize lesions to the central rather than peripheral nervous system since they occur at or above the optic chiasm. Depth perception is facilitated by this trait, which combines separate fields of view to perceive 3D images.

ANSWER: binocularity [accept answers that indicate the involvement of both eyes; accept stereoscopic vision or stereopsis]

[10m] A dilated pupil in a “down and out” directed eye can indicate the oculomotor nerve’s compression by this type of abnormality. Berry examples of these abnormalities, which occur within the brain’s circle of Willis, can cause sudden death due to excessive hemorrhaging.

ANSWER: aneurysm [accept Berry aneurysm]

[10h] Lesions to the MLF, a white matter tract, in multiple sclerosis cause this visual motor impairment characterized by an inability to adduct (“uh-duct”) the ipsilateral eye and the nystagmus of the contralateral eye.

ANSWER: internuclear ophthalmoplegia [or INO] (The MLF is the medial longitudinal fasciculus.)
