A procedure performed under local or general anesthesia to assess mechanical restrictions of eye movements. It involves grasping the conjunctiva with forceps and attempting to rotate the eye in the direction of the restricted movement. A positive forced duction test, where rotation is limited, indicates a tight muscle or other mechanical restriction causing the strabismus. In contrast, a negative test suggests paralysis of the extraocular muscle.
