2002, Sunita Agarwal, Athiya Agarwal, David J. Apple, Textbook of Ophthalmology, Jaypee Brothers Medical Publishers, India, psge 338, If we tilt the head to the right, the right eye will intort and the left eye will extort. […] So, if the right eye intorts, it means the superiors in that eye (RSR and RSO) work and if the left eye extorts it means the inferiors of that eye (LIO and LIR) work.

Figure 18.12. The needles are withdrawn from the sclera, and the sutures are pulled to advance the anterior tendon laterally, while the eye is intorted by rotating it with the large hook.

These conditions are reversed after every hemicycle, i.e. the previously higher intorted eye is then lowered and extorted, and the previously lowered extorted eye becomes higher and intorted (Fig. 3.7).
