Investigation of injection depth for subretinal delivery of exogenous glutamate to restore vision via biomimetic chemical neuromodulation.

Chemical neuromodulation of the retina using native neurotransmitters to biomimetically activate target retinal neurons through chemical synapses is a promising biomimetic alternative to electrical stimulation for restoring vision in blindness caused by photoreceptor degenerative diseases. Recent research has shown that subretinal chemical stimulation could be advantageous for treating photorecept...
