Detailed Anatomy of the Lateral Rectus Muscle-Superior Rectus Muscle Band

Figure 2

The anatomy of the lateral rectus muscle-superior rectus muscle (LR-SR) band and its relationship with adjacent structures. (a) The orbital part of the lacrimal gland (LG) covers the LR-SR band, and the intermuscular septum is shown anterior to the LR-SR band. (b) After excising the orbital part of the LG, the anterior border of LR-SR band is revealed. (c, d) After excising the intermuscular septum, the whole LR-SR band is revealed and connected lateral rectus and superior rectus pulleys. Arrows indicate the intermuscular septum between the LR and SR. Arrowheads indicate the LR-SR band. ON = optic nerve; srP = superior rectus pulley; irP = inferior rectus pulley.
