Purpose
To describe a case of endogenous endophthalmitis caused by the bacterium Abiotrophia/Granulicatella adiacens, which clinically appeared consistent with fungal endophthalmitis, in a young patient with a history of intravenous (IV) drug use.
Observations
A 22-year-old male presented with one week of pain and decreased vision in the left eye. He had a history of IV heroin use. Slit lamp and dilated fundus exam revealed significant intraocular inflammation concerning for endogenous endophthalmitis. The initial clinical impression was of fungal endophthalmitis given the appearance of vitreous opacities consistent with fungal balls. However, vitreous sampling revealed Abiotrophia/Granulicatella adiacens, a species of fastidious gram-positive cocci formerly known as nutritionally variant streptococci.
Conclusion
We describe Abiotrophia/Granulicatella species causing endogenous endophthalmitis in a patient with a history of IV drug use. Abiotrophia/Granulicatella have not been described previously to cause endophthalmitis. This atypical case expands the spectrum of microorganism’s clinicians should consider when diagnosing and treating endogenous endophthalmitis.
