| Research Abstract |
We have tried to develop an artificial vision by direct optic nerve electrode and in the clinical trial, some of the patients recognized the improvement of visual function after the electrical stimulation through optic nerve. We could not find the effect of the improvement of visual function with the electrical stimulation in this acute study using rats. We then tried to develop the materials and methods to examine the effect with larger animals in chronic study.
