One recognized complication of trabeculectomy with visually devastating potential is blebitis. We present a case of a 74-year-old woman with a culture and polymerase chain reaction-positive Abiotrophia defectiva bleb-associated endophthalmitis. Abiotrophia defectiva is a rare but possible cause of endophthalmitis secondary to blebitis and should be considered in culture-negative cases. Prompt identification, hence directed eradication, of the causative organism in such visually threatening cases may be facilitated by requesting polymerase chain reaction and 16S ribosomal RNA sequencing.
