Internuclear Ophthalmoplegia (INO)

[@RegularHarry]

Dr. Lee is legitimately so talented to make me feel I understand something in 4 minutes.

[@shyamamin8117]

Now INO how INO works. Thank you!

[@jamesbeatty-wilson5290]

Something like the thinman am I right!?

[@jeremiahbaker6396]

😂u sure do

[@ovo5326]

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.

[@SiamSentin3l]

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.

[@stingray-j2597]

It is totally a well-earned “mic-drop boss” moment.. thank you Dr Lee, you are transforming Neuro-ophthalmology a fascinating area of study for me

[@docchethanr]

Dr.Lee I see passion in you You are my inspiration

[@B3bita1215]

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!!!!!!!

[@OkanVKILIC]

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.

[@mertinan99]

Hocam sizi ne bıktırdı hastalar mı hastane mi hocalar mı

[@shna2018]

How and where I can see Dr.Lee?

[@sunvavachi]

For the longest time in internal medicine I was trying to figure this out. This was so simply explained and to the point, loved it. Thank you!

[@beriorroch2617]

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!

[@faheema7]

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!

[@drnagarjunaneuro255]

I could understand INO in comprehensive way only after watching this video 5yrs back.. Thank you so much sir🙏 Now I'm sharing this with my juniors

[@jordanjensen6954]

That was truly a mic drop moment at the end of this vid. Well taught

[@neilmansfield8329]

This man is so addictive You can’t stop watching

[@rokusvandendool4563]

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 !

[@MouseHandStrong]

That INO breakdown was legit

[@AlexandraCampbell-y8i]

Studying for my medical school neuro exam and this video was SO helpful -- Thank you!!!

[@smellypatel5272]

Amazing video that simplifies a difficult topic. Thank you doctor!

[@SundusAwan-r7e]

Wonderfull, differentiating between the midbrain and pons is an excellent pointer , never thought about it. Thank you

[@ActuallyCurious1402]

Literally the best!! Thank you doctor Andrew

[@salomiurfriend]

OH MY GOODNESS!!. DR LEE IS LEGIT. how easily are you explaining this. Subscribed!

[@hanadihajdinovichajdinovic3485]

I am at the end of my neurology studies. Dear D.r Lee you help me so much Thank you very much.

[@brainandsynapse]

Dr. Lee, thank you so much.

[@PropheticFate]

What an absolute baller, I like his excitement too! 1 day before step 1 but im getting sucked into his youtube wormhole...

[@MichaelvoxTFIF]

Studying for Step 1 and I just couldn’t figure this out. Thank you!

[@Baraa.K.Mohammad]

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!

[@MayorMcThicc]

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.

[@rainbowbear121]

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 :)

[@DS-tx1uc]

Fantastic teaching video , thank you Dr. Lee

[@dhumaleajit]

Beautiful explaination!

[@王浩源-v3q]

Dr. Lee is so enthusiastic!

[@freecheese4143]

Bless you, sir, for your thoroughness.

[@graciephil]

Simplified explanation. Thank you so much!

[@Auditt09]

Fantastic explanation!! Thank you!

[@JeffCohn]

Are you taking new patients? I would be curious about treatment solutions?

[@federicaiannuzzi6858]

GENIUS THANK YOU DOCTOR

[@DrBrandonBeaber]

Excellent explanation.

[@nwizg523]

Doc is an excellent teacher

[@MayorMcThicc]

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.

[@wongtongsoup22]

These videos are gold, thank you!

[@enas3785]

Thank you Doctor Lee!!

[@Shantanu.Shandilya]

[@raghadraghad7976]

You are AMAZING

[@karamrabi1890]

THIS IS LEGENDARY

[@Inoboy1]

I love watching this shit when I'm stoned and wearing 3d glasses 👓

[@roshanyaday7857]

thank you for the brilliant explanation.. but i was wondering if what will happen if we cover the better side and check uniocular movement in the lesion side????

[@sunvavachi]

Thats an interesting question! Maybe the right eye upon adduction it will have slight horizontal nystagmus compensating for the left eye maybe? I hope they answer your doubt!

[@aadilamin3951]

Uniocular movts will be normal ...as the 3rd nerve nuclues as well as nerve is intact Only binocular movt is affected in INO

[@noufhassan2876]

YOU ARE AMAZING! THANK YOU

[@AGRAJMishra-r6m]

wow. you made it so simple'

[@ajithpandiyan2893]

Please add description to the explanation it will help more sir

[@NeurologyAnalogy]

If it helps, I've made a INO animation on my channel with subtitles. Covers BINO, WEBINO, one and half syndrome, half and half syndrome and the Posterior INO of Lutz

[@malachibeck8086]

Incredible

[@marvin4ever100]

I've been suffering of this type of sickness since 2005.. Pls tell me how can avoid this.

[@Redwine004]

Greetings.. I got it also since three weeks ago doctor had diagnose me. How is your progress? Maybe we couldd share information for this INO..

[@ahmadalosman4110]

Thank you very much

[@bennguyen1313]

If your eyes can converge in the center, then the issue might be "caudal" and the problem is in the Pons.. otherwise it's rostral / midbrain .. however aside from classification purposes, does this have any practical effect on the treatment? According to Kaberi B. Feroze / Jim Wang, when the cause of Internuclear Ophthalmoplegia is MS, infection, or trauma, there is a good chance of complete recovery.. i.e when INO is the only neurological symptom. But less likely to recover if the cause is a stroke or other cerebrovascular problem.

[@picasso1334]

Great explanation

[@NeurologyAnalogy]

Agreed. Mainly for localisation purposes rather than anything else.

[@ega0117]

Is there are cure for it Dr?
