What is inferior oblique Overaction?
In primary inferior oblique muscle overaction, an upshoot of the adducting eye occurs when gaze is directed into the field of action of the inferior oblique muscle, producing a greater upward excursion of the adducted eye than of the abducted eye.
What action does the inferior oblique do?
[2] The inferior oblique is responsible for extorsion, elevation, and abduction. Because of their course, the superior and inferior oblique muscles are the only muscles that can depress or elevate the eye, respectively when the eye moves in adduction.
