Visual evoked potentials were examined in released prisoners of war (POWs) in order to evaluate the extent of neurological impairment after imprisonment in Serbian detention camps. On two occasions visual evoked potentials were determined in a group of 11 released prisoners of war (POWs): 157 days and 379 days after release from detention camp. During the first examination no significant differences were found in VEP parameters between the right and left eye. However, during the second examination significant differences were found in the latencies of waves P100 and N145, statistically significantly prolonged latencies of the P100 wave and significantly greater amplitudes of waves P50 and N75. The results can be regarded as progression of the VEP changes in the released POWs. It is hypothesized that these changes are a result of a demyelination process, caused by the altered immunological status of the POWs during posttraumatic stress syndrome.
对视神经诱发电位进行了检测，以评估被释放的战俘在被关押于塞尔维亚拘留营后神经损伤的程度。对一组11名被释放的战俘进行了两次视神经诱发电位测定：从拘留营获释后的157天和379天。在第一次检查中，右眼和左眼的VEP参数未发现显著差异。然而，在第二次检查中，发现P100波和N145波的潜伏期存在显著差异，P100波潜伏期在统计学上显著延长，P50波和N75波的振幅显著增大。这些结果可被视为被释放战俘VEP变化的进展。据推测，这些变化是脱髓鞘过程的结果，是由战俘在创伤后应激障碍期间免疫状态改变所致。
