The present work proposes an electronic waveform generator for transcorneal electrical stimulation (TES). The applied waveform model is generated into a digital processor by means of an adaptive finite impulse response (FIR) filter, which output waveform is synthesized from the original one registered using a multi-focal electroretinograph (MF-ERG). The stimulation waveform applied in patients with central retinal artery occlusion (CRAO) in this procedure, is qualitatively different from the one reported by others like Tano et. al. [1, 2]. Results show that CRAO patients stimulated with the proposed waveform, reported phosphenes associated with variations of the filter coefficients.
