Question
What are the differences between pediatric superior oblique muscle paresis and superior oblique muscle paralysis?
Answer
Unilateral superior oblique muscle paresis refers to the paralysis of both the superior rectus and inferior oblique muscles in one eye. Clinical symptoms include downward deviation of the affected eye, often accompanied by horizontal strabismus and ptosis of the upper eyelid. This ptosis is usually pseudo- or mixed-type, which can make diagnosis difficult.
