This Guinea Pig presented with a red, painful eye. After applying a topical anesthetic, the eyelids relaxed enough that I could see something protruding from under the upper lid. Soon, I was removing two rather large pieces of hay that had somehow gotten lodged under the lid. I had also applied fluorescein stain which adheres to ulcerated areas of the cornea. You can see the green crescent-shaped area near the top of the cornea where the hay had rubbed off the superficial layer of cells. The guinea pig had immediate relief, and the ulcer should heal within a few days. That was a satisfying appointment for everyone!
