Artificial Retina Update 2011

Yes there is treatment. I have a recent video on Retinal Detachment that will explain what is happening and how it is treated. Good luck with you son.

Sir , Iam suffering from retinitispigmentosa , can l recover fronm this disease by artificial retina transplantation , sir plz help me

[@waratenko]

fantastic!

@DragonfallCIA Thanks for the comment. This video shows only one of a number of strategies in development, because it is farthest along. There is another group working on attaching to the optic nerve, and another attaching to the brain, but they are not as far along. If you want to read more details about work worldwide check Humayun's book, "Artificial Sight," published by Springer in 2007. (It's pricey so you might want to find it in a library.)

Great illustration ! So these electrodes send impulses directly to ganglion cells Or bipolar cells bypassing photoreceptors ? would it make a difference if these electrodes are under the retina or on the retina ? Thanks a lot

Thank you for your hard work! Let us all hope for the brighter future of technological innovations! Per aspera ad astra!

So there is a "compression" or conversion of 1:125 done before the signals (125 million receptors) go to the optic nerve (1 million paths). This conversion or code seems to be what Dr. Sheila Nirenberg of Weill Cornell Medical College is revealing to the world now (Aug 2012). Would using that code with the new 200 "pixel" implant effectively change it into a 25000 resolution implant? That would be a great software upgrade! Any thoughts on this "code"? You are really doing wonderful work.

My ten years son is having retinal detachment is there treatment for that.

Right, 125 rods or cones to every ganglion cell. (Plus there are excitatory and inhibitory actions within the retina by horizontal and amacrine cells.) So there is a lot going on. Dr Nirenberg's recent work on "cracking the code," the info contained in the train of nerve impulses, is exciting. Looking forward to reading more details. Retina 2.0?
