Clinical characteristics and caloric testing in patients with light or heavy cupula of the horizontal semicircular canal

Clinical characteristics and caloric testing in patients with light or heavy cupula of the horizontal semicircular canal

ObjectivesPersistent direction-changing positional nystagmus (DCPN) and null point (NP) are characteristic of cupulopathy of the horizontal semicircular canal (HSC). The cupulopathy can manifest as HSC-light cupula (HSC-Lcu) (geotropic DCPN) and HSC-heavy cupula (HSC-Hcu) (apogeotropic DCPN) in the...
