Forced duction test Edit
The forced duction test is performed in order to determine whether the absence of movement of the eye is due to a neurological disorder or a mechanical restriction.
The anesthetized conjunctiva is grasped with forceps and an attempt is made to move the eye ball in the direction where the movement is restricted. If a mechanical restriction is present, it will not be possible to induce a passive movement of the eye ball
