术前PVEP联合PERG检查对评价老年性白内障患者术后视功能的意义

摘要

AIM:To discuss clinical significance of comprehensive preoperative pattern visual electrophysiological ( PVEP ) testing for assessing postoperative visual function in senile cataract patients. 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 =0.0000. 05), and the detection results of PERG combined with PVEP and BCVA after operation were positively correlated (r=0. 773, P0. 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.%目的：探讨术前综合视觉电生理检测在评估老年性白内障患者术后视觉功能中的临床意义。　　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,P0.05),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。
