Objective      To investigate the value of visual evoked potential (VEP) Combined with multifocal electroretinogram (mfERG) in the diagnosis of ocular contusion.       Methods      VEP

electroretinogram (ERG) and mfERG were detected in 44 patients with unilateral optic nerve contusion

and the results were compared with those of contralateral healthy eyes. In addition

VEP and mfERG consistency in diagnosis of eye contusion was analyzed

and the correlation of the VEP

mfERG

injury duration and visual acuity was further analyzed.       Results      There were significant differences in the amplitude and the latency of pattern VEP (P-VEP) P

100

(P0.05)

and in the amplitude of mfERG (P0.05) and the amplitude of flash VEP (F-VEP) P1 (P0.05) between the damaged eyes and the contralateral healthy eyes

but there was no significant difference in ERGs. The injured duration had no correlation with the amplitude and the latency of P-VEP P

100

and mfERG

but the visual acuity was significantly relevant with the amplitude and the latency of P-VEP P

100

and the amplitude of mfERG.       Conclusion      Ocular trauma can lead to optic nerve damage and also may be associated with decreased macular function. The combination analysis of VEP and mfERG is beneficial to early diagnosis of ocular trauma

and can improve the positive rate in clinic practice.
