方法：选取2013-01/2014-01期间在我院治疗的老年性白内障患者102例126眼，对术前图形视觉诱发电位(PVEP)、图形视网膜电流图(PERG)和PVEP联合PERG的检测结果与术后最佳矫正视力(BCVA)进行比较。

结果：PVEP联合PERG检测一致率达到91.3%，PVEP检测为63.5%，差异有统计学意义(χ²=27.773，P=0.000)； Spearman秩相关分析发现，PVEP检查结果与术后BCVA无显著相关性(r=0.241，P>0.05)，而PERG联合 PVEP的检测结果与术后BCVA呈正相关(r=0.773，P<0.05)。术前PVEP检测正常者占51.6%，而术后占65.1%，差异有统计学意义(P<0.05)，而术前PVEP和PERG联合检测正常者占80.9%，术后占84.1%，差异无统计学意义(P>0.05)，说明PVEP和PERG联合检测评估术后视功能的稳定性好。

结论：老年性白内障患者术前PVEP联合PERG检查能有效、客观的评估患者术后患眼视功能恢复情况。

METHODS: During the period of January 2013 to January 2014, 102 cases of senile cataract patients(126 eyes)were treated in our hospital. The detection result of the preoperative PVEP, electroretinogram(PERG), PVEP combined with PERG and postoperative best corrected visual acuity(BCVA)were compared.

RESULTS: Consistent rate of PVEP combined with PERG detection was 91.3%, that of PVEP was 63.5%, the difference was statistically significant(χ²=27.773, P=0.000< 0.05); Spearman rank correlation analysis showed that there was no significant correlation between PVEP findings and postoperative BCVA(r=0.241, P>0.05), and the detection results of PERG combined with PVEP and BCVA after operation were positively correlated(r=0.773, P<0.05); Preoperative PVEP examination was normal accounted for 51.6%, and after operative accounted for 65.1%, the difference was statistically significant(P<0.05), preoperative combined detection of PVEP and PERG was normal accounted for 80.9%, after operation was accounted for 84.1%, with no significant difference(P>0.05). The combined method of PVEP and PERG to evaluate the postoperative visual function had good stability.

CONCLUSION: Preoperative PVEP joint PERG examination can effectively and objectively assess postoperative visual function recovery in senile cataract patients.
