It was about 1976 that I saw my first subpalpebral medication system used on a horse with a severe corneal ulcer. I’m not sure of the medical outcome, but I remember clearly that this horse fought the procedure when I approached the withers to insert the medication into the tube. She was almost impossible to medicate the eye directly into it or through a medication system similar to the one pictured here. However, the horse in these pictures accepted the fluid going into her eye without resistance.
