Case Report: Ocular Tissue Diagnosis of Previously Undiagnosed, Extensively Drug-Resistant Pulmonary Tuberculosis

Abstract

ABSTRACT. We describe a patient with concurrent ocular and pulmonary tuberculosis (TB) in whom the diagnosis of extensively drug-resistant TB was made through phenotypic drug-sensitivity testing of an ocular fluid sample after sputum testing yielded incomplete results. Our results are remarkable, because culture-based diagnosis of TB in ocular fluid is unusual. We not only overcame this limitation, but also were able to create a complete drug-sensitivity testing profile from ocular samples, which led to effecting appropriate therapy for the patient.
