Summary
Orbital tuberculosis (TB) is a rare condition that presents diagnostic challenges. Early suspicion and targeted investigations are crucial for managing this rare extra-pulmonary TB manifestation.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Pathology
Background:
- Orbital tuberculosis (TB) is a rare form of extrapulmonary TB.
- Diagnosis is challenging due to non-specific symptoms and potential for destructive complications.
Observation:
- A retrospective review of mandatory notifications and surgeon surveys identified three cases of orbital TB in Victoria between 1994 and 2016.
- All identified patients had emigrated from TB-endemic regions.
Findings:
- Diagnosing orbital TB proved difficult due to scarce or non-viable acid-fast bacilli and low culture yield in orbital specimens.
- Orbital TB requires a high index of clinical suspicion, especially in patients from endemic areas.
Implications:
- Orbital TB is an important differential diagnosis for orbital masses.
- Effective management necessitates multidisciplinary collaboration between ophthalmologists, infectious disease specialists, and pathologists.

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.

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...

In an atom, the negatively charged electrons are attracted to the positively charged nucleus. In a multielectron atom, electron-electron repulsions are also observed. The attractive and repulsive forces are dependent on the distance between the particles, as well as the sign and magnitude of the charges on the individual particles. When the charges on the particles are opposite, they attract each other. If both particles have the same charge, they repel each other.
