Amblyopia and optic nerve degeneration

Could anisometropic amblyopia that has gone untreated for decades cause optic nerve degeneration, since that eye is essentially ignored by the visual cortex? Could such a condition be treated by correcting the eye's refractive error, prism lenses, orthoptics, or some combination of the three?

And how is retinoscopy performed? Do you use the automated refractor to find the inital settings for the phoropter, then shine the retinoscope through the phoropter into the eye, and fine-tune the refractive settings that causes the light to stay stationary? How do you test for astigmatism using retinoscopy? Which is superior, streak or spot retinoscopy? What's the difference b/w retinoscopes and ophthalmoscopes? Retinoscopy vs. ophthalmoscopy?

Thanks!!!

the answer to your first question is no. the answer to your second question is it depends. the answers to all of your other questions are pretty detailed and would require lengthy explanations. even as a first year ophthalmology resident with an introduction to optics, I'm not sure I could have answered all of them. may I suggest that you look at one of the stickies entitled 'all first year residents should use this refraction tutorial' for a primer on retinoscopy?

Am i the only one who's feeling really sorry for the poor ophthalmologist who has the OP show up in his routine clinic?
