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