主观视觉垂直线和水平线检查软件的研发与应用

目的 自主研发主观视觉垂直线(SVV)、主观视觉水平线(SVH)检查软件。主要用于判断双侧耳石器功能的对称性和优势偏向侧,评估耳石器功能的静态代偿状态,指导前庭康复。 方法 研发SVV/SVH检查软件,结合消除视觉参考的桶状设备及暗环境检查室,收集80例健康志愿者检查数据,确定正常参考值范围。研究方法为横断面研究。 结果 80例健康志愿者,SVV检查平均值偏离度范围为:-3.00°~3.00°,其平均值的均值(±标准差)为:-0.29(±1.42)°;SVH检查平均值偏离度范围为:-4.00°~3.50°,其平均值的均值(±标准差)为:-0.38(±1.84)°。 结论 自主研发的SVV/SVH软件95%正常值参考范围分别为:-3.13°~2.55°,-4.06°~3.30°;此检查软件和设备可以用于前庭耳石器机能状态的评估,与其他前庭检查设备如前庭诱发肌源性检查、双温试验、甩头试验等相结合,全面评估患者的前庭功能和前庭代偿状态,指导前庭康复。

Invention and application of subjective visual vertical and horizontal examination software

Objective To develop software to examine the subjective visual vertical(SVV)and subjective visual horizontal(SVH). These parameters are mainly used to determine the symmetry and dominant side of bilateral otolith function, evaluate the static compensation state of otolith function, and guide vestibular rehabilitation. Methods The SVV/SVH software was developed and combined with a visual reference barrel device, and used in a dark examination room to collect data from 80 healthy volunteers to determine the normal reference range. This study was a cross-sectional study. Results In the 80 healthy volunteers, the average deviation of the SVV examination ranged from -3.00° to 3.00°. The mean(± standard deviation)was -0.29(±1.42)°. The mean deviation of SVH ranged from -4.00° to 3.50°. The mean value(± standard deviation)was -0.38(±1.84)°. Conclusion The 95% normal reference ranges of the SVV and SVH measured using the software were -3.13 to 2.55° and -4.06 to 3.30°, respectively. The software and equipment can be used to evaluate the functional status of the otolith. Combined with other vestibular examinations, such as vestibular-evoked myogenic potentials, caloric test, and video head impulse test, the software can be used to comprehensively evaluate the patients vestibular function and vestibular compensation status and guide vestibular rehabilitation.
