Can a lazy eye be fixed?
I have a lazy eye. It can't be rectified because it's something to do with the brain not connecting with the eye properly. why can't that be fixed, in general terms?
Well it's very difficult to change the connections within the brain. In a lazy eye, we're looking at a relatively normal retina and optic nerve. It's actually the connections in the brain. And there are some 10^10, to 10^11 neurons in the brain, each of these may have 50 or even 100 different connections. You can imagine how many potential connections there are, to rewire and remodel. And I think really at the moment that's beyond what we can do.
