Cranial Nerve 4 Palsy

[catnjoey22]

My daughter suffered from a mandibular fracture and head trauma and now she has six nerve palsy I've noticed she has difficulty reading, walking straight,on the stairs too. She's never ever had any eye problems. Shes been seen by seven doctors And an opthomoligist she's never seen before just diagnosed her with Duane's 3 can Duane's be caused by head trauma????

No need to apologize for "beating this to death". That's exactly what your viewing audience here was hoping for. Thanks!!

This is the first time I've actually understood why you ask a patient to look down and in when u test for superior oblique rather than the movement it makes (which is down and out)!! I've asked a million neurologist to explain it, and none of them ever did! Thank you so much for this!

@yazmannn instead....I didn't undertand! why u test down and in?

[yazmannn]

@richiupliftmofo So using the analogy of the elbow and arm pulling at 2:15, he explains why the same muscle (the superior oblique) can move the eye in two different ways depending on where the eye is looking. If the eye is looking towards the nose the elbow pulling pulls it down. If the eye is looking out, then the same elbow movement turns the eye. So you ask the patient to look down and in, because thats when the SO muscle pulls the eye down. Hope that made sense.

@yazmannn aahhhhhhhhhhh ok! I've got it! thank u very much. I understand why is so difficult to diagnose! ;)

[jamiemirams1990]

Fantastic video, I'm a medical student and up till now had trouble understanding a CN IV palsy, thanks for making it so clear and understandable!

[chudalison]

you do great videos. The pictures are very uncomplicated and easy to understand. Can you please do more.

What do you think about

slightly enlarged iris in right eye

slightly unalligned, i.e. looking just a little bit down compared to the other eye.

Noticed in last 2.5 years

When tired, right eye wants to close

muscle underneath the right eye seems a little bigger than left.

Can you please brain storm on what this condition could be. I have been to many dx

thanks

Great video, easy to understand. Even for this 9th grader. Cavernous sinus what!

This is an excellent explanation for a difficult nerve palsy. A favourite question on oral exams.
