Multifocal electroretinogram indicates visual field loss in acute zonal occult outer retinopathy

Am J Ophthalmol. 1998 Sep;126(3):466-9. doi: 10.1016/s0002-9394(98)00117-2.


Purpose: To report alterations of electrophysiologic tests, including the multifocal electroretinogram, in a case of acute zonal occult outer retinopathy.

Method: We recorded photopic, scotopic, and single-flash electroretinograms and a multifocal electroretinogram in a 47-year-old woman with acute zonal occult outer retinopathy in the right eye.

Results: Her visual acuity was 20/20 in the right eye throughout the follow-up period. The electroretinograms indicated retinal impairment of the right eye, predominantly in the cones. The multifocal electroretinogram showed reduced responses corresponding to the visual field defect of the static perimetry.

Conclusions: In acute zonal occult outer retinopathy, impairment of the retinal area results in a visual field defect. The multifocal electroretinogram can be useful in determining the location of the defect.
