Isolated Nocardia exalbida endogenous endophthalmitis.

PURPOSE

To report an immunocompetent patient with Nocardia exalbida endogenous endophthalmitis.

DESIGN

Case report.

METHODS

Clinical-pathologic correlation and microbiologic evaluation were performed on an enucleated eye.

RESULTS

A 56-year-old man presented with rapidly progressive vision loss associated with a posterior choroidal mass and serous retinal detachment. Pathologic evaluation of the enucleated eye demonstrated endogenous endophthalmitis. Nocardia exalbida was identified microbiologically. Systemic workup failed to demonstrate definite foci of systemic infection or evidence of immunocompromise. Review of literature failed to identify previously reported cases of Nocardia exalbida endophthalmitis.

CONCLUSIONS

Nocardia can rarely cause isolated endogenous endophthalmitis in immunocompetent patients, which can contribute to a delay in diagnosis and vision loss. Endogenous Nocardia endophthalmitis typically occurs in immunocompromised patients with disseminated nocardiosis. Isolated endogenous Nocardia endophthalmitis in immunocompetent patients is rare. We describe isolated endogenous intraocular infection caused by Nocardia exalbida, a novel species, not previously associated with endophthalmitis.
