Endophthalmitis Caused by Abiotrophia Defectiva after Anterior Vitrectomy in a Child.

Endophthalmitis caused by Abiotrophia defectiva has never before been reported in a child. We report a case of a 12-year-old female with a history of penetrating keratoplasty, followed years later by open globe injury and repair, and subsequent anterior vitrectomy, which resulted in endophthalmitis caused by Abiotrophia defectiva. We review previous cases of endophthalmitis by this organism and argue that its detection will become more common with the use of 16S rDNA PCR and MALDI-TOF mass spectrometry.
