An immunocompetent patient manifested endophthalmitis signs 48 hours after an uncomplicated cataract surgery by phacoemulsification. A bacteria of the family Micrococcaceae was cultured in the vitreous biopsy, namely R. mucilaginosa. The patient did not show a favorable clinical response after vitrectomy and systemic, intravitreal, and topical fortified antibiotics. The patient's eye was very painful, and consequently, it deemed necessary to perform an evisceration. R. mucilaginosa may be an aggressive etiologic agent for postoperative endophthalmitis. Although the isolated R. mucilaginosa was susceptible to empirical treatment, it was impossible to control the infection with standard treatment, probably due to its ability to create a biofilm around the intraocular lens.
