Presenting video-oculography showing spontaneous downbeat nystagmus with a torsional component beating toward the left side (upper eye poles). Straight head hanging position slightly enhanced spontaneous nystagmus. A therapeutic Demi-Semont maneuver for BPPV involving the non-ampullary arm of the right posterior semicircular canal is shown (AVI 15411 kb)
Post-treatment video-oculography showing a total receding of spontaneous nystagmus. Right Dix-Hallpike maneuver still elicited a subtle positional downbeat nystagmus with a torsional component beating toward the left ear (upper eye poles) probably consistent with few residual debris within the non-ampullary arm of the right posterior semicircular canal (AVI 15044 kb)
