Summary
A rare case of choroidal tuberculoma caused sudden vision loss in a young woman. Prompt antitubercular treatment led to complete resolution of the lesion and vision recovery.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Immunology
Background:
- Tuberculosis (TB) can manifest in the eye, though choroidal involvement is uncommon.
- Ocular TB may present insidiously, potentially leading to delayed diagnosis and treatment.
- Solitary choroidal granulomas are rare presentations of TB.
Purpose of the Study:
- To report a unique case of a solitary choroidal tuberculoma causing sudden vision loss.
- To highlight the diagnostic utility of fundus fluorescein angiography in such cases.
- To emphasize the successful management and visual outcome with antitubercular therapy.
Main Methods:
- Case presentation of a 22-year-old woman with unilateral vision loss.
- Systemic evaluation including tuberculin skin test and lymph node biopsy.
- Ophthalmic examination with fundus fluorescein angiography.
Main Results:
- A solitary choroidal granuloma with exudative retinal detachment was diagnosed.
- Tuberculosis was confirmed via lymph node biopsy.
- Fundus fluorescein angiography revealed characteristic findings of the choroidal lesion.
- Complete resolution of the tuberculoma and full vision recovery occurred after treatment.
Conclusions:
- Choroidal tuberculoma can be the initial manifestation of disseminated tuberculosis.
- This case represents the first report linking choroidal tuberculoma to the diagnosis of tuberculous lymphadenitis.
- Early diagnosis and treatment of ocular TB are crucial for visual prognosis.

01:29Pulmonary 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.

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:

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...

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...

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
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 progression...

01:22Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
