Summary
Early steroid use in presumed ocular tuberculosis patients without anti-tuberculous therapy can worsen vision. Corticosteroids before treatment may lead to poor visual outcomes and severe chorioretinal lesions in ocular tuberculosis.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Immunology
Background:
- Ocular tuberculosis is a significant cause of uveitis.
- Accurate diagnosis and timely treatment are crucial for visual preservation.
Purpose of the Study:
- To evaluate the impact of corticosteroid administration timing on visual outcomes and ocular complications in patients with presumed ocular tuberculosis.
Main Methods:
- Retrospective review of 49 patients diagnosed with presumed ocular tuberculosis.
- Patients were categorized based on whether they received corticosteroids before or after anti-tuberculous therapy (ATT).
- Visual acuity and development of chorioretinal lesions were assessed at 1-year follow-up.
Main Results:
- Patients receiving corticosteroids before ATT had significantly poorer visual acuity at 1-year follow-up compared to those who did not (69% vs 30%, p = 0.007).
- Early corticosteroid use was associated with a higher incidence of severe chorioretinal lesions (70% vs 26%, p = 0.019).
Conclusions:
- Pre-treatment corticosteroid administration in presumed ocular tuberculosis may negatively impact visual prognosis.
- The increased severity of chorioretinitis lesions in patients receiving early steroids could explain the poorer visual outcomes.

Pulmonary Tuberculosis I
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
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.

Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
Pulmonary Tuberculosis III
Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Pulmonary Tuberculosis II
Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
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 IV
Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
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...

Tuberculosis
Tuberculosis (TB) remains a significant global health concern, primarily targeting the lungs and spreading through airborne transmission. Infection begins when aerosolized droplet nuclei, expelled by an individual with active TB, are inhaled by another person. These microscopic particles carry Mycobacterium tuberculosis, the causative agent of TB. Upon reaching the alveoli, the bacilli are engulfed by alveolar macrophages. However, due to their specialized lipid-rich cell wall, these pathogens...
