4. REPEAT SUPINE ROLL TEST AFTER ABORTED APPIANI MANEUVER SHOWS CONVERSION TO THE GEOTROPIC VARIANT

The supine roll test after the aborted Appiani maneuver, showed bilateral geotropic horizontal positional nystagmus, which was predictably stronger on right side compared to the left, confirming conversion to the geotropic variant. The geotropic horizontal positional nystagmus was not seen at the first instance but on repeating a supine roll test on the right side during the ongoing maneuver it was clearly seen.
