Visual evoked potentials (VEP) were determined in two groups of released prisoners of war (POWs) from Serbian detention camps during the war in Croatia 1991/92. The first group comprised 22 POWs (group I), examined 10 to 60 days after release, and the second group comprised 24 POWs (group II), examined 6 to 9 months after release. The third group comprised 36 control subjects. Statistically significant increases in the amplitude of waves P50, N75, P100, N145, and significant prolongation of the latencies of wave N145 were found in group I. In group II, significant increases were found in the latencies of waves P50, N75, P100 and N145, and increased amplitude of wave P50. The greater significance of wave latencies compared to amplitudes, and greater significance of changes in early VEP waves than later VEP waves, can be considered evidence of future progression of these changes in the released POWs. This was confirmed by the significant increases in VEP parameters in groups I and II, which exceed +/- 2SD of the relevant control group, and significantly greater number of the same parameters in group II in relation to group I. There was no significance (i.e. asymmetry) among the three groups when the parameters of the determined visual evoked potentials were compared for the left and right eye.
1991/92年克罗地亚战争期间,对两组从塞尔维亚拘留营获释的战俘进行了视觉诱发电位(VEP)检测。第一组包括22名战俘(第一组),在获释后10至60天接受检查;第二组包括24名战俘(第二组),在获释后6至9个月接受检查。第三组包括36名对照受试者。在第一组中发现P50、N75、P100、N145波的波幅有统计学意义的增加,以及N145波的潜伏期有显著延长。在第二组中,发现P50、N75、P100和N145波的潜伏期有显著增加,以及P50波的波幅增加。与波幅相比,波潜伏期具有更大的显著性,并且早期VEP波的变化比晚期VEP波的变化具有更大的显著性,这可以被视为这些获释战俘中这些变化未来进展的证据。第一组和第二组VEP参数的显著增加超过了相关对照组的±2SD,并且第二组中相同参数的数量相对于第一组显著更多,这证实了上述观点。当比较所测视觉诱发电位左右眼的参数时,三组之间没有显著性差异(即不对称性)。
