Summary
Corticosteroids should be avoided in uveitis until the cause is identified. Prompt diagnosis and treatment of ocular tuberculosis led to improved vision and reduced inflammation.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Rheumatology
Background:
- Corticosteroids are commonly used to manage uveitis, a condition causing ocular inflammation.
- Undiagnosed infectious causes can lead to adverse outcomes with immunosuppressive therapy.
- Behçet's disease is a systemic inflammatory disorder that can affect the eyes.
Observation:
- A patient with a history of Behçet's disease presented with blurred vision and chorioretinitis.
- Polymerase chain reaction analysis of vitreous fluid identified Mycobacterium tuberculosis.
- The patient was receiving systemic corticosteroids and immunosuppressants at the time of presentation.
Findings:
- Treatment with anti-tuberculosis drugs resolved the patient's vitritis and improved chorioretinitis.
- This case highlights the risk of masking or exacerbating infections with empirical corticosteroid use.
- Early microbiological evaluation of ocular fluids is crucial for accurate diagnosis.
Implications:
- Empirical corticosteroid use in uveitis should be reconsidered until infectious etiologies are ruled out.
- Ocular fluid analysis can detect specific pathogens missed by routine examinations.
- Timely diagnosis and targeted therapy are essential for managing infectious uveitis and preventing vision loss.

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
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...

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
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...

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
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.

The phylum Chlamydiae or Chlamydiota is composed of a single order, Chlamydiales. This phylum consists entirely of obligate intracellular parasites that infect eukaryotic hosts. While human pathogens within this group have been studied extensively, the phylum encompasses many species capable of interacting with various eukaryotic organisms. Members of Chlamydiae are typically small cocci, approximately 0.5 μm in diameter, and exhibit a distinctive developmental cycle. As is characteristic...
