Abstract
Retinal disease is responsible for many instances of vision impairment. Often, individuals with vision impaired due to retinal disease continue to have functioning retinal neurons. Thus, systems, methods, and devices to stimulate retinal neurons may restore sight for vision-impaired individuals. Systems, methods, and devices provided herein direct ultrasound energy into retinal neurons and modulate phase and amplitude of ultrasound energy in time and space domains in order to variously stimulate various retinal neurons, generating neural responses consistent with visual reproduction of intended images.
