Kocuria Endophthalmitis: Clinical Spectrum and Long-term Outcomes

ABSTRACT

Purpose

To expand the knowledge regarding the clinical presentation of Kocuria endophthalmitis.

Methods

We included six cases of Kocuria endophthalmitis between January 2018 and December 2020. From all cases, we collected general demographic data, relevant medical, ophthalmological history, microbiological and antibiotic sensitivity results. All cases had a minimum follow-up of 9 months. All cases were treated with intravitreal moxifloxacin and dexamethasone and pars plana vitrectomy. Undiluted vitreous, corneal, conjunctival, and aqueous samples were cultured and analyzed with the Vitek 2 system.

Results

The prevalence of Kocuria endophthalmitis was 6%. (95%CI: 2.26%-12.73%). The mean age at diagnosis was 60.5 ± 15.5 years. All patients had poor visual acuity, severe pain, and severe conjunctival hyperemia at diagnosis. Only one case had a significant improvement in visual acuity at the end of the follow-up.

Conclusion

Kocuria spp are an emerging cause of endophthalmitis and should be considered as part of the differential diagnosis.
