Abstract:
PURPOSE: The purpose of this study was to present a case of indolent endogenous endophthalmitis in a young, seemingly healthy woman. METHODS: This study is a retrospective case report. RESULTS: A 25-year-old woman with no significant medical history presented with vision loss in the left eye over the course of 1 month. Examination showed vitritis and a white-yellow lesion overlying the macula and optic nerve in the left eye. Initial laboratory testing for infectious and inflammatory causes was unrevealing. A diagnostic vitrectomy was performed, and the patient was found to have presumed endogenous endophthalmitis due to Streptococcus anginosus, an extremely uncommon bacterium. Subsequent workup did not reveal evidence of bacteremia, endocarditis, or orbital infection. This case is unique because, unlike the three previously reported cases of S. anginosus endophthalmitis, this patient was seemingly healthy, never had an elevated white blood cell count, never had documented bacteremia, had a normal echocardiogram, and had normal orbital findings on magnetic resonance imaging and computed tomography scans. Further questioning revealed a remote history of facial cellulitis and possible sinusitis treated with oral antibiotics, which are the presumed etiology. CONCLUSION: Streptococcus anginosus endophthalmitis can occur in young, seemingly healthy patients. Endogenous endophthalmitis should be considered in the differential diagnosis even without systemic comorbidities or other risk factors. Detailed questioning about medical history and thorough review of systems, including nonocular symptoms, are essential.
