We have a situation here where a young man was brutally attacked. His trochlear nerve was damaged. He presents exactly as you describe. We have no medical background and limited access to medical services. Thank you, your video helped us understand. What is the likely prognosis for a full recovery and how long could it take?

Superior oblique rotates the eye medially, doesn't it?. In that wat trochlear nerve palsy would lead to eye being lateraly rotated.

Hey doctor, I have trochlear palsy, but if I close my non affected eye I can fully move my affected eye like there is no palsy. What could be the explanation? Thank you!
