    Introduction and Classification

    Sorting orbital vascular lesions by how blood moves through them

    • What counts as a vascular disorder of the orbit?
    • The key idea: hemodynamics (how the blood flows)
    • Rootman's three hemodynamic types
    • Reading the three types in plain English
    • The clinical classification used in this chapter
    • Neoplasm versus malformation - a vital distinction

    Carotid-Cavernous Fistula

    A secondary lesion: high-pressure arterial blood short-circuits into a vein

    • What is a carotid-cavernous fistula (CCF)?
    • Direct versus indirect fistulae
    • Barrow angiographic classification of CCF
    • Two very different natural histories
    • Where the blood goes decides the picture
    • Clinical presentation - the classic picture
    • The quiet dural fistula and its complications
    • Imaging the fistula
    • Treatment - protect vision, preserve the artery
    • Treating the indirect fistula, and mopping up
    • How does hemodynamics (flow) unify the whole classification of orbital vascular lesions?
