Sample question 1
Explanation
The superior oblique is innervated by the trochlear nerve, which is cranial nerve IV. It is the only extraocular muscle supplied by CN IV and is part of the classic LR6, SO4, all others III pattern.
Sample question 2
Explanation
Esotropia is a manifest inward deviation of one eye relative to the other. It is one of the basic horizontal strabismus patterns recognized on primary examination.
Sample question 3
Explanation
The Hirschberg test estimates ocular alignment by assessing the position of the corneal light reflex in each eye. It is a simple screening method that is especially useful in children and uncooperative patients.
