Figure 1: The orbit illustrating definitions of anatomical distances. (1): the distance from the anterior border of the lateral rectus muscle-superior rectus muscle (LR-SR) band to the SR insertion; (2): the length of the attachment site between the LR-SR band and the SR: (3), the distance from the anterior border of the LR-SR band to the LR insertion; (4): the length of the attachment site between the LR-SR band and the LR; (5): the width of the LR-SR band. ON = optic nerve; LR = lateral rectus muscle; SR = superior rectus muscle.
