Clinical Characteristics in Patients with Light Cupula
摘要
Abstract
Objectives To report clinical characteristics of patients diagnosed with light cupula.Methods Eigh-teen patients who demonstrated persistent horizontal geotropic direction-changing positional nystagmus (DCPN) by Roll test at our vertigo clinic were enrolled from July 2016 to August 2017.In addition to medical history,videonystag-moscopy (VNG) and Supine Roll test were used to further determine characteristics of positional nystagmus and the plane in which nystagmus disappeared.All patients were treated with the Barbecue roll maneuver,and efficacy was eval-uated immediately and 1 months after treatment.Results Fourteen of the cases were determined to have primary light cupula,while the rest 4 cases had either secondary or concomitant light cupula.Concurrent sudden deafness was present in 4 cases,history of migraine in 4 cases(22.2%)and pregnancy in 2 cases.In all patients,persistent horizontally fixed directional nystagmus and geotropic direction-changing nystagmus were induced in the supine and lateral positions,re-spectively,with the nystagmus disappearance plane being on the affected side.Spontaneous nystagmus was seen in the upright position in only 2 cases (1.1%).Despite Barbecue maneuvers for a week in 16 cases,none showed complete symptom resolution with an improvement rate of merely 18.8% and non-response rate of 81.2%.Treatment was suspend-ed and patients were re-evaluated after a month and showed a complete symptom resolution rate of 75%,an improve-ment rate of 12.5% and a no change rate of 12.5%.Conclusions The clinical characteristics in this group of patients with persistent geotropic direction-changing positional nystagmus are basically consistent to presence of light cupula by theory.The exact pathogenic mechanism is unknown.The affected side can be determined according to the neutral point test in patients with light cupula.Repositioning maneuvers appear to be ineffective,but the condition seems to show a tendency of self-healing.关键词
