  Introduction: Fractionated stereotactic radiosurgery (fSRS) is an effective definitive treatment for optic nerve (ON) tumors. It is controversial whether treatment to the ON requires attention to the position of the eye as some consider the movement to be negligible. We investigated in four patients to establish whether there is clinically significant displacement of the ON as the globe moves and the effect this may have on target coverage in fSRS treatments. Method: Four patients receiving radiotherapy treatment to the skull and requiring cone beam computed tomography (CBCT) matching were asked to look in different directions as routine CBCT were obtained. An fSRS plan was created, treating the ON with the patient looking straight ahead. The displacement of the ON from straight was measured, with the patient looking fully left or right, the DVH of the optic nerve in the three locatio.. Read More»
