以半视野图形翻转视觉诱发电位(H-PRVEP)评价33例鞍区肿瘤的视觉功能,所用参数包括P100潜伏期、波幅、时程三大类,发现有关潜伏期参数是较理想的指标。对造成参数分析差异的原因进行了探讨。
The visual function of 33 cases of sellar tumors was evaluated by reversing visual evoked potentials (H-PRVEP) in semi-field patterns. Parameters used included P100 latency, amplitude and duration. The relevant latency parameters were found to be ideal indicators. The reasons for the differences in parameter analysis were discussed.
