Chronic Postoperative Endophthalmitis Caused by Actinomyces meyeri

We report a female patient who developed chronic endophthalmitis after an uneventful cataract surgery. Cultures of aqueous humor and a vitreous sample showed positivity for Actinomyces meyeri. Intense anterior segment inflammation and a less evident impairment of the patient's posterior segment led us to treat her vigorously with pars plana vitrectomy combined with intraocular and topical antibiotics. The patient achieved a good recovery of vision without the need to remove the intraocular lens and to add systemic drugs. To the best of our knowledge, this is the first reported case of an intraocular infection caused by A. meyeri after small-incision clear corneal phacoemulsification.
