PDT4CNV pretty much nailed it. I have nothing useful to add, other than to say that I despise neuro-ophthalmology. If you are into neurology and the thinking side of opthhalmology, great. However, in my experience most people who entered ophthalmology do not tend to enjoy neuro-ophth. It does not offer the same "mix of surgery and medicine" as other specialties, skewing much more heavily towards clinic and much less towards surgery. Note that most of the surgeries PDT mentioned are not really exclusive to neuro, except maybe temporal artery biopsies (because no one else wants to do them) and optic nerve sheath fenestrations (ack.). It just seems to me that neuro-ophth is either skewed too much towards neurology or it is something you might do in addition to your mainly general practice.
Anyway, just one person's opinion. Please don't anyone rip on me too much - I definitely appreciate having neuro-ophthalmologists around, I just have absolutely no desire to be one. I would welcome a pro-neuro-ophth viewpoint, maybe I've just been missing something.
Finally, as for your questions. . .I doubt it matters exactly how you set up your rotation.
