摘　　要：本文报道了检测图形视网膜电图所用的引导电极的研制。通过对20例正常人的图形视网膜电图检测.对比了银钩状电极(仿 Arden 电极)、DTL 丝状电极,角膜缘接触电极的检测应用。结果表明:角膜缘接触电极为较好的 P-ERG 引导电极。该电极有以下优点:1.导电性能好;2.电极与角巩膜接触良好.接触面大.固定良好:3.不影响视力;4.不损伤角膜;5.易清洗,易消毒,可反复使用。缺点是部分受检者诉异物感。This essay reported the manufacturing process of a special electrode for P-ERG.Through 90 normal persons'P-ERG measured and three special electrode types for P-ERG,including imitation of ARDEN electrode and DTL electrode and LC electrode,wre compared in measurment for P-ERG. The result showed that LC electrode was the best electrode for P-ERG.has several advantages:1.lower resistance;2.excellent contact to limbus corneae;3.rio influenee on vision;4.easy clean and sterilization.
