Now doctors are conducting experiments with laboratory rats. Some of the attempts to preserve alive the optic nerve already lead to success. However, the specialists face a number of challenges that need to be addressed.

The eye is an extension of the brain. Body has a few shells of complex structure. Visual information enters the brain through the nerve. While scientists do not know how to splice alien nerve with the nervous system of the recipient. Work in this direction are just beginning.

Scientists currently have a drug inhibitory of the gene of the visual neurons. At the same time, none of the operations on animals by transplanting the optic body has yet to be successful.
