Description
𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: Range: Assesses for motility deficit due to an ocular motor palsy, particularly if a posterior fossa localization is being considered; Nystagmus: Spontaneous nystagmus may or may not be noted and gaze-evoked nystagmus is common with posterior fossa lesions; nystagmus that is unidirectional in all directions of gaze can be peripheral or central; bidirectional nystagmus (changing direction on right versus left gaze) is central Instructional ocular motor examination procedures. 𝗡𝗲𝘂𝗿𝗼-𝗼𝗽𝗵𝘁𝗵𝗮𝗹𝗺𝗼𝗹𝗼𝗴𝘆 𝗮𝗻𝗱 𝗡𝗲𝘂𝗿𝗼-𝗼𝘁𝗼𝗹𝗼𝗴𝘆 𝗧𝗲𝘅𝘁𝗯𝗼𝗼𝗸 𝗟𝗲𝗴𝗲𝗻𝗱: Assess versions (both eyes viewing) and ductions (each eye individually viewing), especially in patients with diplopia or when a motility defcit is suspected. Look for spontaneous nystagmus or saccadic intrusions/oscillations in primary gaze and gaze-evoked nystagmus in eccentric gaze. https://collections.lib.utah.edu/ark:/87278/s6vt51rq
