Case 6 — Oscillopsia and falls in the dark
Vignette
A 68-year-old retired engineer describes two years of progressively worse unsteadiness, three falls in the past year (all on uneven ground or in dim light), and 'bouncing' of his visual field when he walks briskly or drives over rough roads. There is no rotational vertigo, no hearing change, and no history of aminoglycoside exposure. Bedside head impulses are abnormal in both directions for lateral canals.
