Multifocal electroretinogram in branch retinal vein occlusion.

Abstract

To describe the response from multifocal electroretinography in branch retinal vein occlusion. Prospective observational case control series. Multifocal electroretinography was recorded in 15 patients with temporal branch retinal vein occlusion and 21 control subjects using a visual evoked response imaging system. There were significant differences in mean amplitude (P =.01) and latency (P =.001) between thrombotic and nonthrombotic retina in the same eyes, as well as in patients compared with control subjects. Responses from multifocal electroretinography demonstrate retinal dysfunction in branch retinal vein occlusion; additional studies will demonstrate whether multifocal electroretinography has a prognostic value.
