目的:探讨图形视觉诱发电位(PVEP)在眼外伤性视神经挫伤中的应用价值。方法:对49例临床诊断为外伤性视神经挫伤的单眼患者进行PVEP测定,并与自体健侧眼进行对照。结果:挫伤眼与自体健侧眼比较,P100波幅差异有极显著意义(P<0.01)、P100峰潜时与正常值比较有明显差异(P<0.01)。结论:PVEP对视神经挫伤的诊断有一定的临床价值。

·AIM:To explore application value of pattern visual evoked potential in patients(PVEP)with optic nerve contusion following ocular damage.·METHODS:PVEP detection was performed in 49 patients with optic nerve contusion diagnosed clinically,and the results were compared with the contralateral healthy eyes.·RESULTS:There was extremely significant differece in amplitudes of P100 among the damaged eyes and the contralteral healthy eyes(P<0.01).There was a significant differece in amplitudes of P100among the damaged eyes and the contralteral healthy eyes(P<0.01).·CONCLUSION:PVEP has certain clinical value in the diagnosis of optic nerve contusion.·
