Superior oblique myokymia is a neurological disorder affecting vision and was named by Hoyt and Keane in 1970. [1]It is a condition that presents as repeated, brief episodes of movement, shimmering or shaking of the vision of one eye, a feeling of the eye trembling, or vertical/tilted vision.
These movements can lead the patient to wake up, and if so, sleep interruption can be the origin of excessive daytime sleepiness. [2] PLMD is characterized by increased periodic limb movements during sleep, which must coexist with a sleep disturbance or other functional impairment, in an explicit cause-effect relationship.
Some cases have been reported on rhythmic movements during wakeful activities like driving. When occurring in sleep, RMD episodes are more likely to onset during non-REM, stage 2 sleep. Roughly 46% of sleep-RMD episodes occur only in non-REM sleep; 30% in non-REM and REM; and only 24% strictly in REM sleep. [12]
