Background:
Orbital tuberculosis (OTb) is rare and may be regarded as a manifestation of extrapulmonary tuberculosis. We report an interesting case series of six patients with varied presentations of orbital and adnexal tuberculosis in a South Indian patient population.
Results:
A retrospective, interventional case series of six patients diagnosed with orbital and adnexal tuberculosis on the basis of clinical, radiological and histopathological evaluations between 2010 and 2013 was performed. Among the six patients with histopathologically proven OTb, five were women. The varied presentations included tubercular dacryoadenitis (two cases), classical periostitis (two cases), OTb with bone involvement (one case) and ocular adnexal tuberculosis (one case). Systemic involvement was seen in one case. All cases were treated with a regimen of antitubercular therapy (ATT).
Conclusions:
OTb, though rare, should form a part of the differential diagnosis of orbital lesions in a high tuberculosis (TB) endemic country like ours. Biopsy still remains the mainstay of diagnosis.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
