Ocular manifestations of tuberculosis.

OBJECTIVE

To present the clinical and histopathologic findings in five cases of tuberculosis (TB) with various ocular manifestations.

DESIGN

Observational case series.

METHODS

Retrospective review of clinical findings, course, and treatment of five patients. Diagnostic techniques, including biomicroscopic, histopathologic, and molecular biologic test results, are presented.

MAIN OUTCOME MEASURES: Visual acuity, slit-lamp biomicroscopy, indirect ophthalmoscopy, and fluorescein angiography results.

RESULTS

The ocular manifestations of TB in our patients included panophthalmitis, endophthalmitis, posterior uveitis with choroidal tubercles, keratitis, and a lid mass. Mycobacterium tuberculosis was identified in four cases in ocular specimens using acid-fast bacilli microscopy and in three cases by culture. Rapid diagnosis using polymerase chain reaction was obtained in one case. Extraocular foci of TB were identified in three cases with an intraocular infection at presentation. No patients had the human immunodeficiency virus (HIV) and none were immunocompromised. Two eyes could not be saved using antituberculous treatment because of delayed diagnosis and treatment.

CONCLUSIONS

In this age of the HIV pandemic, TB is becoming more common. Because it is curable, heightened awareness and better understanding of the disease's ocular manifestations should be of concern to all ophthalmologists.
