Orbit and Visual Pathways

The various compartments of the orbit lend themselves to a geographical analysis of lesions involving the orbit. Thus one often finds classifications of orbital diseases describing ocular abnormalities involving the globe vs. intraconal non-ocular abnormalities involving the soft tissues within the muscular cone, conal abnormalities involving the extraocular muscles, and extraconal abnormalities involving those lesions outside the muscular cone. In addition there are specific diseases that affect the orbital “appendages”, which include the lacrimal glands, lacrimal sac, and conjunctivae.
