Patients with bilateral weakness (BW) have many difficulties in gaze stability that interfere with their normal function. The aim of this study was to evaluate ocular motor functions in patients with BW to better understand the problem of gaze instability in these patients.
Patients were referred from the Otolaryngology Department for Vestibular Assessment to our clinic between November 2014 and March 2015. We assessed ocular motor function (gaze, saccade, and smooth pursuit) in patients over the age of 18 years with BW, as verified by a caloric test.
Seventy-eight patients completed all the tests. The mean age of patients was 51.9 (±15.9) years, and 47 (60%) were female. Abnormal results were found in five (6.4%), 32 (41%), and seven (9%) patients with respect to gaze, smooth pursuit, and saccade, respectively. There were positive but relatively weak relationships between age and ocular motor results.
Patients with BW suffer from dizziness and unsteadiness. These patients have abnormal function in ocular motor (especially smooth pursuit) tests. The ocular motor dysfunction is responsible for gaze instability in static positions such as standing.
双侧无力(BW)患者在注视稳定性方面存在诸多困难,这会干扰他们的正常功能。本研究的目的是评估BW患者的眼动功能,以便更好地了解这些患者的注视不稳定问题。
2014年11月至2015年3月期间,患者从耳鼻喉科转诊至我们的诊所进行前庭评估。我们评估了18岁以上经冷热试验证实患有BW的患者的眼动功能(注视、扫视和平稳跟踪)。
78名患者完成了所有测试。患者的平均年龄为51.9(±15.9)岁,47名(60%)为女性。分别在5名(6.4%)、32名(41%)和7名(9%)患者中发现注视、平稳跟踪和扫视结果异常。年龄与眼动结果之间存在正向但相对较弱的关系。
BW患者存在头晕和不稳。这些患者在眼动(尤其是平稳跟踪)测试中功能异常。眼动功能障碍是导致站立等静态姿势下注视不稳定的原因。
