Purpose:
To report a case of polymicrobial keratitis caused by Panotea agglomerans, Escherichia vulneris and coagulase-negative Staphylococcus in a patient who cleaned their extended wear contact lenses with only tap water for 2 weeks.
Methods:
Case report.
Results:
An adult presented with a painful red eye after wearing the same contact lenses for two weeks. The patient admitted to taking the contacts out in the evening and cleaning them with tap water before reapplying them in the morning. Exam revealed a 2.5 mm paracentral corneal ulcer in the left eye. Culture results from corneal scrapings were positive for Panotea agglomerans, Escherichia vulneris and coagulase-negative Staphylococcus.
Conclusions:
This is the first report of Panotea agglomerans and Escherichia vulneris keratitis in association with contact lens wear. Both strains of Panotea agglomerans and Escherichia vulneris were pansensitive to all tested antibiotics.
