Unreferenced stub auto yes date December 2009 Seealso Degenerate energy level Degenerate orbitals for electron s in an atom ic electron shell subshell are Atomic orbital orbitals at identical energy levels. These are important in physical chemistry because they affect the ways electrons fill atoms see Hund s rule . For example, all the 3p orbitals have same energy level, and so do all the 5d orbitals. Each orbital is defined as if it lies along a set of x, y, z axes. The 2p orbitals are thus 2px, 2py and 2pz. The 3p orbitals would be the same shape but larger and at higher energy. Degenerate orbitals play an important role in Molecular Orbital theory. For example, consider the three 2p orbitals. When forming a molecular orbital, the 2px orbital combines with another 2px orbital, the 2py with a 2py and a 2pz with a 2pz. The 2px orbitals combine head on forming sigma bonding and antibonding orbitals. The 2py orbitals and the 2pz orbitals combine separately forming 2 pairs of pi bonding and antibonding orbitals. These pi orbitals are degenerate since they have the same energy different from the sigma orbitals . The sequence for the orbitals is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 ...

When it affects the rear of the eye, it is known as retro orbital cellulitis. It should not be confused with periorbital cellulitis , which refers to cellulitis anterior to the septum. Presentation Patients present with sudden onset of fever, proptosis , restricted eye movement, and swelling and redness of the eyelids. It is usually caused by a previous sinusitis . Other causes include infection of nearby structures, trauma and previous surgery. Prognosis and treatment Because of concern for spread of infection, patients must be admitted to the hospital to receive intravenous antibiotic s. Complications include cavernous sinus thrombosis and meningitis . Abscess formation is another complication and may require surgical drainage. Orbital cellulitis is considered an ophthalmological emergency. Treatment IV cefoxitin or ampicillin sulbactam Surgical decompression of the affected eye.
