Purpose:
To describe an infrequent presentation of ocular tuberculosis.
Design:
Retrospective observational case report.
Methods:
A 61-year-old woman presented with decreased vision in her right eye and cystoid macular edema resistant to periocular corticosteroid treatment. There were no other findings.
Results:
Diagnosis of probable underlying tuberculosis uveitis with macular edema as the only ocular manifestation was established based on a clinical history of possible tuberculosis during her infancy. Additionally, there were residual findings in the patient's chest x-ray, a positive Mantoux reaction, and Mycobacterium tuberculosis in sputum. Specific treatment was implemented for nine months. Cystoid macular edema resolved completely, visual acuity improved (20/20), and no remission occurred during two years of follow-up.
Conclusions:
In cases of idiopathic cystoid macular edema, tuberculosis should be considered as a potential cause. When treated, both are curable.

The first classification is based on the development of the disease, and it includes the following categories:
Tuberculosis
Pulmonary Tuberculosis IV
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...
Pulmonary Tuberculosis II
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...
Pulmonary Tuberculosis I
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.

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 progression...
