PURPOSE: To describe the response from multifocal electroretinography in branch retinal vein occlusion. DESIGN: Prospective observational case control series. METHODS: Multifocal electroretinography was recorded in 15 patients with temporal branch retinal vein occlusion and 21 control subjects using a visual evoked response imaging system. RESULTS: There were significant differences in mean amplitude (p = 0.01) and latency (p = 0.001) between thrombotic and nonthrombotic retina in the same eyes, as well as in patients compared with control subjects. CONCLUSIONS: Responses from multifocal electroretinography demonstrate retinal dysfunction in branch retinal vein occlusion; additional studies will demonstrate whether multifocal electroretinography has a prognostic value.
