Nocardia infection following intraocular surgery: Report of seven cases from a tertiary eye hospital.

PURPOSE: To study the outcome of ocular nocardiosis following intraocular surgery.

MATERIALS AND

METHODS

A retrospective review of medical records of all postoperative cases of culture proven Nocardia infection over a period of 3 years, from October 2010 to September 2013, was performed. Microbiological analysis was performed for all cases and included smears and cultures. Fortified 2% amikacin eye drops were the mainstay of treatment. Surgical intervention was performed in case of nonresponse to medical therapy or suspected endophthalmitis.

RESULTS

Seven cases of culture proven Nocardia infection were seen. All cases had been operated in a hospital surgical facility. Six followed phacoemulsification, and one followed a secondary intraocular lens implantation. Four patients were part of a cluster infection. The mean duration between the primary surgical procedure and presentation was 16.14 ± 9.82 days. Five patients had infiltrates at the site of the surgical incision. One each had endophthalmitis and panophthalmitis. Six eyes required surgical intervention. Infection was seen to resolve in four eyes. Two eyes went into phthisis, and one was eviscerated. Only two of the six eyes, where in surgical intervention was performed early, obtained a final visual acuity of 20/60.

CONCLUSION

Early surgical intervention, before the involvement of the anterior chamber, may help preserve the anatomic and functional integrity of the eye.
