Bacillus licheniformis as a cause of delayed-onset recurrent pseudophakic endophthalmitis-a rare case report.

PURPOSE: To report a case of delayed-onset recurrent pseudophakic endophthalmitis caused by Bacillus licheniformis.

METHOD: Retrospective review of a case.

RESULTS

A 30-year-old lady (s/p pseudophakia 10 years) presented with features of acute endophthalmitis and a vision of light perception in the left eye. She had received 15 intravitreal injections and systemic corticosteroids earlier for similar complaints. A core vitrectomy and intravitreal antibiotics injection improved her vision to 20/70, although the symptoms recurred a week later. Intraocular lens explantation with a repeat vitrectomy and intravitreal antibiotics was performed. The vitreous/aqueous fluid on both occasions grew B. licheniformis sensitive to fluoroquinolones, vancomycin, and gentamicin. One year after the second surgery, her vision was 20/30 with a quiet eye.

CONCLUSION

This case shows that delayed-onset recurrent endophthalmitis after cataract extraction may be caused by Bacillus spp. and, despite sensitivity to most antibiotics, may require intraocular lens explantation for eradication of the infection.
