Retinal Impants

Retinal implants are a new technological advance that is used to help patients see that lost their sight due to degenerative eye conditions. People with degenerative eye conditions loose there site due to the retinal cells losing their ability to sense light. The retinal implants help take over for the job of sensing the light. The next generation of retinal implants that has just received approval from the FDA, is a tiny chip with tiny hair-like electrodes. When the chip is implanted in the retina, it sends messages to the neural cells in the brain that send the information to the brain.

The result of the new generation of retinal implants seems very promising. The new generation of retinal implants almost quadrupled the number of electrodes from 16 to 60. Having a device with 60 electrodes is does not give the patient very clear vision better than having nothing. I believe the retinal implants have a very promising future. It may take many years to have an advancement that would let people see very clearly, but I think with the retinal implants it can be possible.

Which do you prefer, subretinal or epiretinal?
