Effects of Electrical Stimulation on Retinal Morphology as Seen with Optical Coherence Tomography

Retinal prostheses provide blind patients with the ability to detect motion and locate large objects. Future implants will require null smaller electrodes to improve resolution, but increased charge density may result, creating a safety concern. We developed a null novel in vivo method to study the effects of electrical stimulation in the retina using real time Optical Coherence Tomography null (OCT) imaging combined with micropositioning...
