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.

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.
@ashwinikini2435 жыл бұрын
There is loss of supranuclear normal inhibitory response.
@demomann91264 жыл бұрын
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?

what about firing of the inferior oblique muscle? does it show any clinical sign in the Parinaud syndrome?
@wr444 жыл бұрын
Can a unilateral lesion (eg in MS) also nip the trochlear fibres leading to contralateral superior oblique palsy - i.e contralateral hypertropia?
@drakk27064 жыл бұрын
So no 3rd nerve palsy as such?

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.
@karthikvinaymahesh5406 Жыл бұрын
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
