Patient's question:
What is the difference between infantile bilateral superior oblique muscle palsy and bilateral superior rectus muscle palsy? Thank you!Doctor's answer:
Unilateral double superior oblique muscle palsy refers to the simultaneous palsy of the superior oblique muscle and the inferior oblique muscle in one eye. Clinically, it presents with esotropia in the affected eye, often accompanied by horizontal strabismus and ptosis of the upper eyelid. This type of ptosis is usually pseudonymous or mixed, making it prone to misdiagnosis.
