The utility of checkerboard pattern reversal visual evoked potentials in the evaluation of Parkinson disease (Pd) was studied in 25 patients and controls without eye pathology. The results did not reveal differences in potential latency but the amplitude appeared slightly larger in PD than controls. Major intraocular differences were observed only in Pd patients with glaucoma, cataracts or retinal degeneration. The commonly employed high contrast and luminance, checkerboard pattern reversal technique did not appear useful in the evaluation of Pd. Selection of proper stimulus parameters may be critical in detecting VEP abnormality in Pd.
在25例帕金森病（Pd）患者及无眼部病变的对照组中，研究了棋盘格模式翻转视觉诱发电位在帕金森病评估中的作用。结果未发现潜伏期有差异，但帕金森病患者的波幅似乎略高于对照组。仅在患有青光眼、白内障或视网膜变性的帕金森病患者中观察到明显的眼内差异。常用的高对比度和亮度的棋盘格模式翻转技术在帕金森病评估中似乎并无用处。选择合适的刺激参数可能对检测帕金森病患者的视觉诱发电位异常至关重要。
