Rationale:
Compared with intraocular tuberculosis, ocular tuberculosis with ocular surface involvement is rare. Corneal involvement in ocular tuberculosis may include interstitial keratitis or peripheral ulcerative keratitis. We report a case of peripheral ulcerative keratitis directly caused by tuberculosis.
Patient Concerns:
A 20-year-old man complained of vision loss and pain in the left eye that had lasted for 1 week. A slit lamp examination of the left eye showed a corneal epithelial defect, interstitial corneal edema, and a white irregular infiltrative lesion and ulcer (with the dimension of 2 × 2.5 mm) in the inferior temporal region.
Diagnoses:
The corneal ulcer was scraped, and the Mycobacterium tuberculosis deoxyribonucleic acid polymerase chain reaction was positive.
Interventions And Outcomes:
After a month of oral antituberculosis treatment, the corneal ulcer resolved, and the intraocular inflammation improved.
Lessons:
Peripheral ulcerative keratitis secondary to tuberculosis can be directly caused by M tuberculosis.

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