Description
๐ข๐ฟ๐ถ๐ด๐ถ๐ป๐ฎ๐น ๐๐ฒ๐๐ฐ๐ฟ๐ถ๐ฝ๐๐ถ๐ผ๐ป: This is an example of pendular nystagmus, where like jerk nystagmus, the slow phase initiates the movement. However, unlike jerk nystagmus, there is no fast phase, but rather back to back slow phases resembling a pendulum. Pendular nystagmus is named after the vector, making this mainly a horizontal (with a slight elliptical trajectory) pendular nystagmus. This patient presented with ‘sitting' oscillopsia (from her nystagmus) due to a progressive neuro- degenerative disorder (of unknown etiology) that led to severe atrophy of the brainstem and cerebellum over years. ๐ก๐ฒ๐๐ฟ๐ผ-๐ผ๐ฝ๐ต๐๐ต๐ฎ๐น๐บ๐ผ๐น๐ผ๐ด๐ ๐ฎ๐ป๐ฑ ๐ก๐ฒ๐๐ฟ๐ผ-๐ผ๐๐ผ๐น๐ผ๐ด๐ ๐ง๐ฒ๐ ๐๐ฏ๐ผ๐ผ๐ธ ๐๐ฒ๐ด๐ฒ๐ป๐ฑ: This is an example of pendular nystagmus, where like jerk nystagmus, the slow phase initiates the movement.
