Purpose:
To present paradoxical reaction (PR) in three cases with ocular tuberculosis (OTB) treated with antitubercular therapy (ATT), highlighting diagnostic challenges and treatment strategies.
Methods:
We retrospectively reviewed clinical records of three OTB patients presenting with paradoxical worsening after ATT initiation at two Brazilian university hospitals.
Results:
The patients (2 males, 1 female) experienced worsening clinical presentation (increased inflammation, vision loss) within two to three weeks after initiating ATT. One patient who was HIV-positive with unilateral multifocal choroiditis developed PR soon after starting antiretroviral therapy. The second patient presented with a choroidal tuberculoma in both eyes. The third patient also had multifocal choroiditis and developed a localized choroidal elevation with a double-layer sign as a manifestation of PR. All patients were maintained on ATT therapy in association with corticosteroids and experienced improvement of inflammatory signs.
Conclusion:
This case series highlights the potential for PR in OTB patients. Close monitoring and prompt therapeutic adjustments are crucial for management success.

Here is a detailed explanation of its pathophysiology:

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.
