The RETeval Visual Electrodiagnostic Device measures the 30-Hz flicker electroretinogram, which reportedly has a strong correlation to retinal ischemic diseases such as diabetic retinopathy, is used in the monitoring of vigabatrin toxicity, and can be used to distinguish between ischemic and nonischemic central retinal vein occlusion.
RETeval is a handheld screening device that uses skin electrodes, enabling virtually any health care provider to screen a patient in just a few minutes. No dilation is required regardless of pupillary size or the presence of a cataract.
