Ocular tuberculosis

C J Helm1, G N Holland

Survey of Ophthalmology

Summary

Tuberculosis (TB) is reemerging, increasing the risk of tuberculous eye disease, primarily affecting the choroid. Diagnosis involves clinical presentation, PPD skin testing, and careful consideration before initiating treatment due to potential drug toxicities.

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Public Health

Background:

  • Tuberculosis (TB) is a growing global health concern.
  • Ocular TB may increase in prevalence alongside pulmonary TB.
  • Tubercle bacilli typically reach the eye via bloodstream from pulmonary infection.

Purpose of the Study:

  • To review the epidemiology and clinical manifestations of ocular tuberculosis.
  • To discuss diagnostic approaches for tuberculous eye disease.
  • To provide guidance on the management of ocular TB.

Main Methods:

  • Literature review of ocular tuberculosis.
  • Analysis of clinical presentations and diagnostic methods.
  • Discussion of treatment strategies and pathogenesis.

Main Results:

  • Choroiditis is the most common ocular manifestation of TB.
  • Retinal tuberculosis is often secondary to choroiditis.
  • Tuberculoprotein hypersensitivity may contribute to phlyctenulosis and Eales' disease.
  • Ocular and orbital TB are typically unilateral.
  • PPD skin test specificity increases with reaction size and exposure history.

Conclusions:

  • Ocular tuberculosis requires careful diagnosis, considering clinical signs and PPD testing.
  • Empiric treatment for ocular TB should be reserved for high-risk patients due to drug toxicity concerns.
  • Early recognition and appropriate management are crucial for preventing vision loss in ocular TB.
