If only schools also taught the way you did
This video has solved my years of confusion in 5 min.Thank you
Thats pearls indeed dr . Many thnx
Thank you so much for simplifying this objective
You rock. This helped me a lot.
Thanks a lot. A best explaination
Really helpful, thank you so much!
Great Video!
superb video! thank you so much!!!
Amazing video
Thanks ❤️
wowwww .....Thank u man
Mam
1)Why the pupil in ARGYLL ROBERTSON PUPIL is usually constricted?
2) Does pretectal nucles have inhibitory influence of Edinger westphal nucleus?
Please help!

You have a very valid & interesting doubt, Naveen. I am pasting the relevant portion from the link above to answer your question
“Damage to the rostral midbrain can result in AR pupils. Specifically, a lesion of the dorsal aspect of the Edinger-Westphal nucleus can interrupt the pretectal oculomotor light reflex fibers. However, the more ventrally located fibers of the Edinger-Westphal nuclei that control the near reaction are spared.
Supranuclear adrenergic fibers that inhibit the Edinger-Westphal nucleus are necessary for iris sphincter relaxation and pupil dilation. When this inhibitory pathway is disrupted, parasympathetic neurons of the Edinger-Westphal nucleus that naturally fire at a high rate can lead to sustained pupil contraction by the iris sphincter and cause miosis in AR pupils.”
@@ophthalmologypearls thanks a lot mam!🙏
Super ❤
God bless ur father when u invert it for easy refernce
???
@@ophthalmologypearls you invert the picture that was not inverted on previous video and made eyes from down to up like looking infront of patient
@@DrhilmiWhat is the role of her father in inverting the picture
Thank u so much ma'am
Pls make a video on visual field anatomy and field defects for Post graduates

@@ophthalmologypearls Thank u ma'am
It will be very helpful if u could cover visual field defects in neuroophthal as well with relevant anatomy
Thank u ma'am
Is this dangerous
All the situations mentioned here are serious conditions, some of which are temporary and others are permanent. What I described are just manifestations of a wide range of diseases.
