title: Periodic nonalternating ocular skew deviation accompanied by head tilt and pathologic lid retraction.
abstract: A 60-year-old black male with a 13-year history of adult onset diabetes mellitus and hypertension with a previous lacunar stroke suddenly developed a periodic head and eye movement disorder characterized by nonalternating skew deviation, rotatory nystagmus, head tilt, and lid retraction.
