A 63-year-old woman with a history of type 2 diabetes mellitus, tobacco use, poorly controlled hypertension, and recent cataract surgery on her right eye presents to the emergency department with sudden onset of severe pain, decreased vision, and redness of her right eye. Three days ago, she underwent an uncomplicated cataract extraction and lens implantation at an outpatient surgical center. She administered topical prescription antibiotics eye drops postoperatively as instructed. Her symptoms started close to 48 h after the surgery. During the past 24 h, she has experienced increasing discomfort, significant photophobia, and a noticeable decrease in visual acuity on the affected side. She has no fever but states she feels generally unwell. Given the acuity of her complaint, an urgent ophthalmology consult was obtained. After a thorough eye examination, she was taken to the operating room for immediate intervention due to concern for postoperative endophthalmitis.
