20S. F. is medical student and she prepares herself regularly for the ophthalmology practicles. A friend of hers has called her and told her that he has suffered head trauma a day ago. Few hours later he has started having complaints of ”double vision" when looking downwards. Looking in the other directions - he hasn’t had complaints. She has made the right diagnosis immediately
because she is aware of anatomy and physiology of the eye. If you are aware of them, make the right diagnosis and explain why have you chosen this diagnosis and why the other 5 diagnosis are not possible.
(For the answers which contain name of extraocular muscles - circle the number of the cranial nerve which is responsible for the innervation of the certain muscle)
1) dysfunction of m. rectus lat. due to paresis/palsy of [blank_start]VI[blank_end] CN -> [blank_start]No[blank_end] because it innervates the Lateral Rectus
2) partial atrophy of superior 1/2 of the optic nerve -> [blank_start]No[blank_end] because you'd expect blindness
3) partial atrophy of inferior 1/2 of the optic nerve -> [blank_start]No[blank_end], because you'd expect some blindness
4) dysfunction of m. rectus inf. due to paresis/palsy of [blank_start]III[blank_end] CN -> [blank_start]No[blank_end] because it innervates the inferior rectus
5) dysfunction of m. obliquus sup. due to paresis/palsy of [blank_start]IV[blank_end] CN -> [blank_start]Yes[blank_end] because it only innervates this muscle
6) dysfunction of‘rm. obliquus inf due to paresis/palsy [blank_start]III[blank_end] CN -> [blank_start]No[blank_end] because you'd expect other muscles the III CN to be affected as well- AVI
