Fig. 9. 3D reconstruction from serial histologic sections of a human right medial rectus pulley based on immunohistochemistry. The globe is rendered in green, striated muscle in red, collagen in blue, elastin in orange, and smooth muscle in purple. The dense collagen normally present in the inferior part of the pulley has been rendered transparent to demonstrate the embedded elastin and the peribulbar smooth muscle. (Rendering by Joel M. Miller, PhD, and the author.)
