You are the best teacher of neuro-ophthalmology known to me. God bless you! Thank you for inspiring!!!

[@rachedzeghlache5555]

Such a terrific teacher. Not even in my neuro block anymore but I still watch his videos because he's awesome

[@margheritabarzilai703]

[@cecilia1999]

The best explanation that i v ever heard. Thank u!

[@marahal9657]

what a legend ! thank you 1000 times from syria 🌹

[@humzaifat1]

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

[@skdutta6634]

Thanks sir for clearing the concepts🙏🏻

[@heisenbergdalton332]

Amazing 💯

[@berkaygazikara]

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.

فديته احسن شرح يشرح 🤩

[@neuroxplorein]

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)

[@fannyirinapimentelmarmol8613]

Thanks! That’s really help me a lot!

[@shashanksingh8327]

Why some of the videos are private? How can i watch them? They are really awesome. Please help

[@SuperScandar]

what about firing of the inferior oblique muscle? does it show any clinical sign in the Parinaud syndrome?

[@antoniusarifin7193]

Dear dr.Lee, what the best treatment for this ? Is there any exercise? Im suffered from this parinaud syndrome , please your advice🙏

[@demomann9126]

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?

[@MrRyanThaFitz]

Nice Video :)

[@wr44]

Can a unilateral lesion (eg in MS) also nip the trochlear fibres leading to contralateral superior oblique palsy - i.e contralateral hypertropia?

[@patelmruganks]

salute you , sir!!!!!!!!!!!!!!!!!!

[@charlesforsythe5303]

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.

[@ashwinikini243]

There is loss of supranuclear normal inhibitory response.

[@drakk2706]

So no 3rd nerve palsy as such?

[@ikjotsingh4353]

Thank you

[@tomcruise9317]

Lesion is there hpe can 3 rd nerve fire

[@danielrblend]

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.

[@TheDoc4kids]

Not migraine?

[@danielrblend]

@@TheDoc4kids You could classify it as that, but its 24/7 unless I wear digital block glasses non stop.

[@karthikvinaymahesh5406]

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

[@harkarandeepsingh9071]

Hello Sir. Thank you for all your amazing lectures . I am having a little difficulty understanding the vertical gaze pathway . Can you explain that.

[@vineshmanohar2060]

Harkarandeep Singh Even I din’t understand that! I googled it and I’m even more confused now!

[@syahirashariffudin7142]

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..

[@mahamad3091]

Is horizontal gaze affected ?

[@ashwinikini243]

Horizontal gaze center does not reside in the dorsal midbrain.

[@classrealkimify]

Something is wrong with playing this video..

[@zamiranajera5479]

Hay no nevert nevert
