A retinal implant that restores sight to people with disabilities

Every day we find new ways in which science and technology work together to find new ways to treat different disabilities that occur in the human body.
A disease that takes away a vital sense for humans the “retinitis pigmentosa” that is caused by the damage of the photoreceptors of the retina that are slowly causing blindness in a person.

But the University of Tübingen, Germany has developed and implemented a “sub-retinal implants” that consists of 1500 micro-photodiodes and amplifiers installed just below the retina, which transform the image perceived by the eye in a pattern of electronic signals . These micro-photodiodes respond to light, and when its connected to a power supply can stimulate nearby nerves, creating an having effect similar of a normal photoreceptor.

Fortunately the answer of the implants have been truly amazing, providing a slowly returned vision to people with total blindness. Also the solution is not yet complete and still in a stage of development and design.
