Tuberculosis (TB) - an ophthalmic perspective.
Pak J Ophthalmol Jan ;29(1):46-9.

Tuberculosis (TB) is a chronic infection caused by mycobacteria, Mycobacterium tuberculosis. After entry of the organisms in the body, most persons remain asymptomatic, but the infection persists permanently in a latent or dormant state. Active disease occurs when microorganisms begin replicating and it is usually when the immune system fails. The epidemic of human immunodeficiency virus (HIV) infection may have contributed to the increase in TB in the western countries.
