Comparison of mfERG with VEP in NAION Patients and Healthy People

Abstract

Purpose: Comparison of mfERG (multifocal electroretinography)with VEP(vizual evoked potential )in NAION(Nonarteritic ischemic optic neuropathy) patients and healthy people

 

Materials and methods: 44 NAION patients were included in the study.The patients  were 23 woman, 21  male. The average age was  60-83  in NAION group.The patients underwent mfERG and VEP. 35 healthy people formed the control group. In the control group was 19 woman, 17  male. The average age was 57-89 in control group.

 

Results: Mean VEP amplitude 1.89  * 0, 95mV and latency 123,6 * 18,70 msec in NAION  group . In healthy group VEP amplitude was 4.92  * 1, 02mV and latency  was 103,01 * 7.02 msec. There was no obvious pathology in mfERG in patients with NAION and in the control group.

 

Conclusion: In NAION patients, significant changes can be seen in VEP amplitude and VEP latency. This was also found in our work.Ganglion cell and optic disc damage does not change in the mfERG , so abnormal mfERG is probably a reporter of an external retinal lesion.
