A Case of Postoperative Sphingomonas paucimobilis Endophthalmitis After Cataract Extraction

PURPOSE To report a case of an acute onset of delayed postoperative endophthalmitis that was caused by Sphingomonas paucimobilis. METHODS This case demonstrates an acute onset of delayed postoperative endophthalmitis at 3 months after uneventful cataract extraction and posterior chamber intraocular lens implantation. We performed vitrectomy, intraocular lens and capsular bag removal, and intravitreal antibiotics injection. On the smear stains from the aspirated vitreous humor, gram-negative bacilli were detected and S. paucimobilis was found in culture. RESULTS At three months after vitrectomy, the best corrected visual acuity was 20/300. Fundus examination showed mild pale color of optic disc and macular degeneration. CONCLUSIONS Vitrectomy with intravitreal ceftazidime injection had contributed to the favorable result in case of an acute onset of delayed postoperatire endophthalmitis caused by S. paucimobilis.
