In adults, there is some controversy -- most ophtalmologists will tell you there is no chance of retraining, a few suggest that it might be possible, after a long time. I guess it may also depend on the cause of amblyopia. Many cases are due to strabismus, some are caused by other problems. In my case, it seems my left eye was farsighted. There is some ongoing research about retraining in adults, e.g. professor Zhong-Lin Lu, in USC's Laboratory of Brain Processes (
LOBES).
The reason I have not had LASIK is that I don't like even the low risk it presents -- I rely on the one eye that would get the surgery.
Yeah, amblyopia is something that needs to be caught early--the age that seems to stick in my mind is 7. I had/have it as well, due to strabismus. At least in the case of strabismus it is very obvious so it was caught very early (I was totally cross-eyed as a baby) and I had eye muscle surgery at the age of 10 months, as well as having to do the patch thing off and on for a number of years to make my left eye do its share of the work; I also wore glasses all the time from the age of 10 months until I was in high school. I still do not have normal binocular vision (brain doesn't fuse the images from both eyes properly, so the right eye is definitely the dominant one) but the vision in the left eye is about 20/50 and the right is 20/25 or 20/30 so I only wear my glasses now for driving (and legally I don't have to). However, I seem to compensate well for my rotten depth perception other than the fact that I have always been horrendous at sports that involve catching, hitting something out of the air or throwing!!!
