Sir your lessons are just amazing. Pub med/internet/books reaserch was driving me mad but when I found your videos everything got simple.Halleluja! Thanks!!!!
Awesome explanation ! I did not find the reason in usual med ophthalmology books, for sunsetting sign in hydrocephalus, and correct explanation of vertical gaze center, which most book so far I have seen writes it to be within the superior colliculus, rather than thalamo-mesencephalic junction. Awesome sir, thank you
Thank you, for sparing your time to explain this pathology, it is really an interesting "syndrome". It can be seen in pineal gland masses in the pediatric age group. But any problem affecting the midbrain can present with Parinaud Syndrome.
If I need the best explanation of neuro-opthomology signs and pathways, I go to this channel. Honestly no need to supplement (except for examples in real patients)
Question: since the rostral midbrain is being compressed, why is there overexcitation of CN-3 and causing convergence-retraction nystagmoid symptoms? I guess what I am asking is can someone please reexplain this. Thanks.
TBH, it's not a very good explanation of why convergence and retraction occurs with upgaze attempts. Why would the medial rectus pull, unopposed, when you try to look up?
Had a pineal cyst removed earlier this year, was curious what role the mid brain plays in chronic photophobia, if any. In my context, photophobia to me is irritation by light which causes eye pain, headaches moving front to back, sometimes ear and head pressure, and nausea.
In pineal gland tumors or cyst, there are abnormalities in upgaze and pupillary responses, especially inability of the pupils to constrict to bright light . this can explain the photophobia if your pupils are constricting enough to avoid bright light
thank you sir .. i ve just seen 1 case of parinaud syndrome today and thinking where shud i learn it so that i can get clear picture of what parinaud syndrome is. and i ve found it here. thanks again..
Fantastic! Clearly one of the best teachers I have ever seen! Hope to see more videos. Thank you Sir.
He has extraordinary approach, he is different level,the GOAT of neuro, op
What a legend! Thank you so much.
Thank you Dr. Lee for these videos. You make the pathways very enjoyable to learn about. Can't wait for the next video(s). Thanks again.
Such a terrific teacher. Not even in my neuro block anymore but I still watch his videos because he's awesome
Saw a patient who was textbook classic for Parinaud's syndrome. Amazing! Thank you for so clearly explaining.
The best explanation that i v ever heard. Thank u!
I can hear you 24×7. Such a brilliant teacher
You are the best teacher of neuro-ophthalmology known to me. God bless you! Thank you for inspiring!!!

Amazing, THANK YOU!
Wow, I have the feeling you're gonna make my neuro rotation a lot easier
Excellent video ! Thank you.

Love your Videos! Quick & Dirty!
Why some of the videos are private? How can i watch them? They are really awesome. Please help
Can a unilateral lesion (eg in MS) also nip the trochlear fibres leading to contralateral superior oblique palsy - i.e contralateral hypertropia?
what about firing of the inferior oblique muscle? does it show any clinical sign in the Parinaud syndrome?
Dear dr.Lee, what the best treatment for this ? Is there any exercise? Im suffered from this parinaud syndrome , please your advice🙏
So no 3rd nerve palsy as such?
Question: since the rostral midbrain is being compressed, why is there overexcitation of CN-3 and causing convergence-retraction nystagmoid symptoms? I guess what I am asking is can someone please reexplain this. Thanks.
There is loss of supranuclear normal inhibitory response.
TBH, it's not a very good explanation of why convergence and retraction occurs with upgaze attempts. Why would the medial rectus pull, unopposed, when you try to look up?
Hello Sir. Thank you for all your amazing lectures . I am having a little difficulty understanding the vertical gaze pathway . Can you explain that.
Harkarandeep Singh Even I din’t understand that! I googled it and I’m even more confused now!
Had a pineal cyst removed earlier this year, was curious what role the mid brain plays in chronic photophobia, if any. In my context, photophobia to me is irritation by light which causes eye pain, headaches moving front to back, sometimes ear and head pressure, and nausea.
Not migraine?
@@TheDoc4kids You could classify it as that, but its 24/7 unless I wear digital block glasses non stop.
In pineal gland tumors or cyst, there are abnormalities in upgaze and pupillary responses, especially inability of the pupils to constrict to bright light . this can explain the photophobia if your pupils are constricting enough to avoid bright light
Lesion is there hpe can 3 rd nerve fire
Is horizontal gaze affected ?
Horizontal gaze center does not reside in the dorsal midbrain.
thank you sir .. i ve just seen 1 case of parinaud syndrome today and thinking where shud i learn it so that i can get clear picture of what parinaud syndrome is. and i ve found it here. thanks again..
Something is wrong with playing this video..
Hay no nevert nevert
wow, finally some Chinese face, 希望您了解中国文化
Sooooooooooooooooooooooooooo.
