Diagnostic study reveals that combining PCR with conventional culture boosts pathogen detection to 71% in postoperative endophthalmitis, highlighting PCR as a vital diagnostic adjunct.

Key Points

To evaluate the efficacy of broad-range eubacterial polymerase chain reaction (PCR) and direct sequencing compared with conventional culture in identifying bacterial pathogens from ocular samples of patients with postoperative endophthalmitis.
Analyzed aqueous humor collected prior to intravitreal antibiotics and vitreous samples collected during pars plana vitrectomy from 30 patients with acute or delayed-onset endophthalmitis.
Performed broad-range eubacterial PCR amplification followed by direct sequencing alongside standard microbial culture techniques at a university hospital in Lyon, France.
In aqueous humor, conventional culture was positive in 32% of cases, whereas PCR was positive in 61% of cases; combining both methods achieved a 71% diagnostic yield.
In vitreous samples pretreated with intravitreal antibiotics, PCR increased the pathogen identification rate from 18% via culture to 62%.
