Background:
Tuberculosis is a serious, and unfortunately common, infectious disease caused by the organism Mycobacterium tuberculosis. The incidence, mortality, and physical/ophthalmologic effects are well documented. Although most common ophthalmologic findings include optic neuropathy and uveitis, cranial nerve palsies may also present secondary to intracranial inflammation.
Case Report:
A 17-year-old Somalian girl was referred to the eye clinic with the chief concern of intermittent diplopia and headaches. Although monocular visual acuity was excellent, ocular positioning tests confirmed a subtle abduction deficit of the right eye. Medical history was remarkable for active tuberculosis.
Conclusion:
Tuberculosis is a mediating factor for abducens nerve palsy in children. Understanding the relationship between the disease process and ocular ramifications is imperative for competent management.

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.
