[Recurrent acute Enterococcal faecalis endophthalmitis following cataract surgery: a case report with a favorable outcome].

INTRODUCTION: Enterococcal faecalis endophthalmitis is an acute type of endophthalmitis that is exceptional because it is rare, can be recurrent, and has a poor functional prognosis. OBSERVATION: We report a case of recurrent Enterococcus faecalis endophthalmitis after cataract surgery on a 76-year-old woman. After four acute infectious episodes over a few months, this patient recovered without ablation of the IOL. After the classic intravitreous and general antibiotic injections, the treatment required posterior vitrectomy with posterior capsulorrhexis. Only this surgery enabled the cleansing of the vitreous cavity by removing the germs present in the intravitreous abscesses. Despite the responsible germ's virulence, the visual recovery at 7/10 P2 remained stable 2 years after these recurrent infectious episodes. DISCUSSION: As far as we know, this is the only published case of Enterococcus faecalis endophthalmitis that was cured without ablation of the IOL. A review of the literature shows the rarity of acute Enterococcus faecalis endophthalmitis, characterized by recurrences and a poor visual prognosis. The microbiologic and therapeutic particularities of Enterococcus faecalis endophthalmitis are discussed with the objective of elaborating a therapeutic protocol combining antibiotic therapy, corticotherapy, vitrectomy, and posterior capsulorrhexis while leaving the IOL in place.
CONCLUSION: Enterococcus faecalis endophthalmitis is an ophthalmologic emergency, which requires not only a rapid intervention, but also close follow-up to detect recurrences early and perform vitrectomy and posterior capsulorrhexis with as little delay as possible.
