目的 评价改进后的眼震图对先天性眼球震颤波形的分析,为其手术治疗提供较为精确的量化标准。方法 改进电生理仪的视网膜电图(EOG)程序,分别记录68例患者33cm原在位、右5°、10°、15°、20°,左5°、10°、15°、20°,3m原在位及闭眼的波形,并对其中28例手术患者术前和术后的眼震图进行比较。结果 68例患者中,跳动型48例,其中水平跳动46例,垂直跳动2例;水平钟摆型20例。跳动型中,有代偿头位的40例,钟摆型无明显代偿头位。28例手术患者中,水平跳动型26例,水平钟摆型2例。26例跳动型患者均有中间位和代偿头位。术后20例代偿头位消失,6例代偿头位在左5°～10°。按震频、振幅、震强的分组中,处于中等震频、振幅、震强范围内的多见。结论 改进的眼震图可以对眼震的振幅、震频、震强、中间位进行量化的检测,从而指导其治疗。
Objective To evaluate the improved nystagmography on the analysis of congenital nystagmus waveform and to provide a more accurate quantitative standard for its surgical treatment. Methods Electroencephalography (EOG) program was modified and 68 cases of patients with 33 cm original position, right 5 °, 10 °, 15 °, 20 °, left 5 °, 10 °, 15 °, 20 °, 3m original and closed eyes of the waveform, and 28 cases of surgical patients preoperative and postoperative nystagmus for comparison. Results Among the 68 patients, 48 were beating, including 46 cases of horizontal beating and 2 cases of vertical beating, and 20 cases of horizontal pendulum. Beating type, there are 40 cases of compensatory head, pendulum type no obvious head of compensation. Of the 28 surgical patients, there were 26 cases of horizontal beating and 2 cases of horizontal pendulum. 26 cases of beating patients have medial and compensatory head position. 20 cases of compensatory head disappeared, 6 cases of compensatory head in the left 5 ° ~ 10 °. According to the vibration frequency, amplitude, strong earthquake group, in the moderate vibration frequency, amplitude, seismic intensity within the more common. Conclusion The improved nystagmus can detect the nystagmus amplitude, vibration frequency, earthquake intensity and meditope to guide its treatment.
