AI has improved bionic eye technology

Scientists from the United States have presented a new development that will help visually impaired people see better. Especially for this, the new model has improved the implants of patients.

The researchers explained that millions of people around the world experience vision loss due to degenerative eye diseases. Retinitis pigmentosa (or pigmentary abiotrophy) alone affects one in 4,000 people worldwide.

To help them, technology has already appeared that makes their lives better. “Argus II,” the world’s first retinal prosthesis, reproduces some of the functions of the organ – patients with it can perceive the outlines of objects and objects. This allows them to move along the street safely.

Researchers at the University of Southern California (USC) have tried to improve this technology by using an advanced computer model of what happens in the retina. Their experimentally validated model reproduces the shapes and positions of millions of nerve cells, as well as the physical and network properties associated with them.

By focusing on nerve cell models that transmit visual information from the eye to the brain, the researchers identified ways to increase clarity and color vision in future retinal prostheses potentially.

Scientists noted that photoreceptors die-off in degenerative eye diseases, “Argus II” delivers signals directly to these cells.

Thus, the patient receives a tiny eye implant with a set of electrodes. These electrodes are remotely activated when a signal is transmitted from a pair of special glasses on which the camera is mounted. The light detected by the camera determines which retinal ganglion cells are activated by the electrodes, sending a signal to the brain, resulting in a black-and-white image of 60 dots.
