Mrs. A., a 45 year old female was raking leaves in her yard when she accidently scratched her cornea as she pick up a pile of brush. Although her eye was quite painful, she did not seek medical attention. Instead, she used some eye drops her husband received the year before when he had cataract surgery. After 3 days of using the eye drops, mrs. A eye was even more painful and had become red. Her entire eye orbital was swollen and her vision was affected. Finally, on day 4, mrs. A. Saw her eye doctor, who suspected an infection and swabbed her eye. Because mrs. A brought the eye drops along, the doctor plated a sample of the eye drop. My question is what kind of infection does mrs . Have and how should it be treated
