Summary
Orbital myositis, an inflammation of eye muscles, typically presents acutely and responds to steroids. However, atypical forms linked to systemic conditions are increasingly identified, requiring further study.
Area of Science:
- Ophthalmology
- Rheumatology
- Immunology
Background:
- Orbital myositis involves inflammation of extraocular muscles.
- It presents in typical and atypical forms, distinct from thyroid-associated orbitopathy.
Purpose of the Study:
- To review and update current knowledge on all forms of extraocular muscle inflammation.
- To differentiate typical and atypical presentations of orbital myositis.
Main Methods:
- A comprehensive literature review was conducted.
- Focused on extraocular muscle inflammation, excluding thyroid-related conditions.
Main Results:
- Typical orbital myositis is acute, idiopathic, affects young women, causes painful diplopia, and responds to corticosteroids.
- Atypical forms include chronic/recurrent cases and those associated with systemic autoimmune (e.g., inflammatory bowel disease), infective conditions, IgG4-related disease, drug reactions, and paraneoplastic syndromes.
Conclusions:
- Orbital myositis has a typical acute steroid-responsive form and increasingly recognized atypical forms linked to specific systemic conditions.
- Similarities with uveitis suggest a need for standardized nomenclature, diagnosis, and treatment approaches.

An atomic orbital represents the three-dimensional regions in an atom where an electron has the highest probability to reside. The radial distribution function indicates the total probability of finding an electron within the thin shell at a distance r from the nucleus. The atomic orbitals have distinct shapes which are determined by l, the angular momentum quantum number. The orbitals are often drawn with a boundary surface, enclosing densest regions of the cloud.

Orbitals are the areas outside of the atomic nucleus where electrons are most likely to reside. They are characterized by different energy levels, shapes, and three-dimensional orientations. The location of electrons is described most generally by a shell or principal energy level, then by a subshell within each shell, and finally, by individual orbitals found within the subshells.
The first shell is closest to the nucleus, and it has only one subshell with a single spherical orbital called the...

The mathematical expression known as the wave function, ψ, contains information about each orbital and the wavelike properties of electrons in an isolated atom. When atoms are bound together in a molecule, the wave functions combine to produce new mathematical descriptions that have different shapes. This process of combining the wave functions for atomic orbitals is called hybridization and is mathematically accomplished by the linear combination of atomic orbitals. The new orbitals that...
