Abstract

The present work proposes a portable electronic waveform generator for transcorneal electrical stimulation (TES). The waveform model is generated into a digital processor, and is based on a healthy eye´s multi-focal electroretinogram (MF-ERG) response. The stimulation protocol proposed in this paper is qualitatively different from the one reported by others like Inomata et. al. Results show an improvement in patient´s visual acuity and increased electrical B wave response in standard electroretinogram (ERG) tests, when TES is applied in patients suffering low vision (LV) produced by central retinal artery occlusion (CRAO).
