良性阵发性位置性眩晕(BPPV)是最常见的位置性眩晕。它是由耳锥移位引起的，耳锥自由漂浮在半规管内(管结石)或附着在顶端(上鼓管结石)。累及外侧半规管(LSCC)的杯状结石型(或重型杯状)BPPV在翻头试验中表现出持续性各向异性方向改变位置性眼震(DCPN)。然而，在某些情况下，不同于任何类型的BPPV，持久性地致性DCPN不能用BPPV的任何机制来解释，也不符合当前的分类。最近，轻杯的概念被引入来指代持久的地致性DCPN。在这项研究中，我们观察了轻度丘疹的临床特征，并讨论了可能的机制和治疗策略。光杯的概念是对周围性位置性眩晕和眼球震颤理论的有益补充。
Benign paroxysmal positional vertigo (BPPV) represents the most common form of positional vertigo. It is caused by dislodged otoconia that freely float in the semicircular canals (canalolithiasis) or attach to the cupula (cupulolithiasis). A cupulolithiasis-type (or a heavy cupula-type) of BPPV implicating the lateral semicircular canal (LSCC) exhibits persistent ageotropic direction-changing positional nystagmus (DCPN) in a head-roll test. However, in some cases, unlike any type of BPPV, persistent geotropic DCPN cannot be explained by any mechanisms of BPPV, and don’t fit the current classifications. Recently, the notion of light cupula has been introduced to refer to the persistent geotropic DCPN. In this study, we looked at the clinical features of light cuplula and discussed the possible mechanisms and therapeutic strategies of the condition. The notion of light cupula is a helpful addition to the theory of peripheral positional vertigo and nystagmus.
