Abstract:·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.·
