[The multifocal electroretinogram in idiopathic epiretinal membrane].
OBJECTIVE
To measure and compare the difference between normal control and patients with idiopathic epiretinal membrane with multifocal Electroretinography (mfERG).


METHODS
Seventeen normal control (20 eyes) and 15 cases (19 eyes) of idiopathic epiretinal membrane were measured with VERIS Science 4.0.


RESULTS
The abnormal mfERG was found in all of the patients with idiopathic epiretinal membrane. There existed statistically significant difference of P1 average response density and N1 latencies in all 6 ring retinal regions between the normal control and patients with idiopathic epiretinal membrane. The visual acuity of the patients were not related to average response densities of the first ring retinal region but correspondent to the latencies of the first ring retinal region.


CONCLUSIONS
The mfERG can be used to evaluate the visual function of patients with idiopathic epiretinal membrane.
