As a medical student, my prof could spend a hour explaining this and yet I still don't understand it. Dr. Lee can do it in 4. No BS straight to the point. Love it.
I love how Dr Lee smirks, turns and walks away from the board at the end of most videos - like an action hero walking away from an explosion behind him! No doubt, Neuro-op is kickass enough to warrant that.
It is ridiculous how easy you made this concept. TWO LONG WEEKS trying to get my head around this, and it only took me 3 minutes to completely understand this. I cannot be more THANKFUL Dr. Lee you're an amazing human being. ❤ May God continue to bless you always!!!!!!!
Dr.Lee your residents and students are so lucky to have such an amazing professor like you, sir. I wish I could have a professor like you, I wouldn't have to quit ophthalmology residency in my home country. It's a pleasure to listening valuable concepts from you.
Just perfect! I saw my first case of INO in a patient and I couldn't really grasp the concept. Everything was so clearly explained in only a four minute video. Thank you!
My sister and I met you at the Ophthalmology Conference in South Africa and you encouraged us to watch your videos and drop you a comment... So here I am.. saying that Dr Lee, you are amazing!
Thanks Dr Lee, this video was very helpful! Also don't forget that anterior and posterior INOs can also have bilateral lesions, giving slightly extra symptoms :)
I was convinced that convergence was always spared with INO, so I was confused when I had a patient who could not converge. Now I know the problem was located in the thalamo-mesencephalic junction! Thank you !
In case someone has the same difficulty; there's this point that confused me and still does because of the inconsistency of anatomical labeling (if want to call it that) which seems random and arbitrary in medical teaching, where they just say right and left (in some cases to be fair) when it does not make any sense.. Left and right, in neuro-anatomy at least, is always concerned with the side that the structure starts in (as far as I remember! please correct me if I'm wrong), but here in this example, the "RIGHT" MLF is meant to be : The MLF that "GOES" to the right side, although it's the one that was sent by the "LEFT" PPRF or "LEFT" VI Abducent nerve. The anatomical labeling of it is "RIGHT" and does not respect the fact that it started in the "LEFT" side and is meant to help the "LEFT" eye bring the opposite eye to do the same movement (conjugate), it is not in respect to that but rather to where it's going. Is this due to the fact that most lesions occur in the portion after it "decussates" to the contra lateral side (the eye which it is supposed to innervate) or in other words is it because the MLF was reduced to just the "longitudinal" part which happens to be on the contra lateral side? This means that when a lesion in the so-called "RIGHT" MLF (the one coming from LEFT CN-VI) is gonna fall short of accomplishing its mission of (conjugating the RIGHT eye's movement with LEFT eye which is intending to ABDUCT [ look laterally or left in this case ] ) i.e. failure of "ADDUCTING" the "RIGHT" eye. PHEWww... Now I get it! lol!
Thank you, I've been rewatching this video for the last 30 mins, trying to understand why Dr. Lee is seemingly contradicting himself in his clinical conclusion, despite initially giving the correct explanation.
1:18 If by the right MLF lesion, you mean left MLF lesion, then yes. Damage to the right MLF (i.e., the MLF originating in the right CN VI) would result in failure to adduct the contralateral (left) eye. If I'm wrong, please someone explain how.
Now INO how INO works. Thank you!
Something like the thinman am I right!?
😂u sure do
Dr. Lee is legitimately so talented to make me feel I understand something in 4 minutes.
