| Resumo: | The present work presents the effect of wavelets waveforms electrical stimulation applied on lowvision (LV) patients suffering central retinal artery occlusion CRAO.Stimulations is done via transcorneal electrical stimulation (TES) by means of an adaptive wavelets system generator. The applied waveform signal is generated into a digital processor, and is based on a healthy eye’s multi‐focal wavelet signal obtained from electroretinography (MF‐ERG) response of healthy people. The stimulation protocol proposed in this paper is qualitatively different from others, like Inomata et. al. [1,2] that uses square bipolar signals. All stimulated patients improve at least one line in Fainbloom’s visual acuity exams scale. Results are correlated with an important increased in the electrical A and B wave response in standard electroretinography and with subjective patient’svisual acuity confirmed by the fact allstimulated patients improve at least one line in Fainbloom’s scale at least, in visual acuity exams. |
