Inflammation of one or more of the tissues within the orbit. Inflammation may be due to a specific known cause eg thyroid eye disease or infection as in bacterial orbital cellulitis. Inflammations without infection may be generalised or specific to certain tissues in the orbit including lacrimal gland (dacroadenitis), muscles (myositis), sclera (scleritis), blood vessels (vasculitis). The underlying cause of these is often not certain. Inflammation may also follow trauma or foreign bodies in the orbit and occasionally occurs with tumours.
