Eye Infection: What's the Culprit?

Case Study: I.C. is a 76-year-old woman who presented to the emergency room complaining of constipation for four days. During the 24 hours preceding the emergency room visit, I.C. experienced nausea, vomiting, and abdominal pain. Evaluation revealed a mass located in the sigmoid colon, and surgical resection was planned. Prior to surgery, I.C. had a short-term subclavian catheter inserted for fluids, total parenteral nutrition, and correction of electrolytes. A sigmoid colectomy was performed, and pathology confirmed adenocarcinoma stage IIa. I.C. seemed to recover from surgery without complication.
