Objectives

To understand the role of ophthalmoscopic examination (dilated retina examination and widefield fundus photography) in the diagnosis and management of nosocomial acquisition of Mycobacterium chimaera following open heart surgery with cardiopulmonary bypass utilizing a heater-cooler unit, an entity that is associated with >50% mortality during the worldwide outbreak that has occurred since 2013.

Methods

Case report with review of previous cases.

Results

Signature Mycobacterium chimaera chorioretinal lesions can be used as a diagnostic sign and a biomarker for assessment of treatment efficacy.

Conclusions
