Summary

Answers to frequently asked questions about equine subpalpebral lavage (SPL) systems, which are used to deliver liquid medications directly to a horse’s eye. An SPL consists of a soft silicone tube placed in the upper or lower eyelid and secured along the face and mane, allowing medication to be administered without handling the eyelids or head. SPLs are especially useful for horses requiring frequent eye medications, those that are painful or difficult to handle, or eyes that are fragile due to ulcers or surgery. The document explains medication delivery methods (air method or stacking method), daily care and maintenance, ways to protect the tubing, and how to monitor for infection or damage. Common complications such as tube tears or loose sutures are discussed, along with basic repair guidance and when to contact a veterinarian.
