The oblique focusing defect of spherical lenses, known as coma, is described by Seidel as the second of five correction terms (third order) to the Gauss theory. The concept is clear for a refracting surface that is free of spherical aberration; however, the impossibility of eliminating spherical aberration from a single lens with spherical surfaces can

Coma and disorders of consciousness are frequently considered in terms of two linked anatomic-functional systems: the arousal system and the awareness system. The mesopontine tegmentum (namely the cuneiform/subcuneiform nuclei of the caudal midbrain and the pontis oralis nucleus of the rostral pons) and the monoamine nuclei generate signals of arousal.
