【摘要】 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。更多还原

【Abstract】 Objective To evaluate a improved electronystagmus and provide more accurate quantificational indexs for congenital nystagmus (CN) surgery by evaluating the CN graph. Methods Using the improved EOG program, 68 patients were recorded for the frequency, amplitude and intensity at 33cm primary eye position, right 5°, 10° , 15°, 20°, left 5°, 10°, 15° , 20°, 3m of primary eye position and closing. 28 cases’ electronystagmus were compared between prior and post operation. Results Of 68 patients, 46 patients were horizontal jerk nystagmus. 2 patients were vertical jerk nystagmus. 20 patients were horizontal pendular nystagmus. 40 patients in 48 jerk nystagmus had null zero and head posturing, while 20 pendular nystagmus patients had not. In the 28 operated patients, 26 patients had null zero and head posturing. After having been operated, 20 cases’ head posturing had disappeared, 8 patients’ head posturing between left 5°-10°. According to the group of frequency, amplitude and intensity at 33cm primary eye position, most patients belonged to middle group in electronystagmus. Conclusion The improved electronystagmus could accurately quantify the frequency, amplitude and intensity of CN, and could be used as a standard for CN surgery.更多还原
