Subpalpebral lavage system

Ocular medications, particularly those used to treat serious conditions such as corneal ulcers, often must be applied multiple times per day or even hourly. Not only is this schedule difficult to maintain for the average horse owner, but the “patient” often becomes resentful of the process, adding to the challenge.

A good alternative is a subpalpebral lavage system, which delivers eye medications frequently and easily. The system, which is put in place by a veterinarian, consists of a long silicone tube that passes through small incisions on the upper or lower eyelid and is secured to the facial skin with sutures. The tubing, which is woven through the mane and draped along the crest of the neck, ends in a closed port secured to the mane. Medication is then injected into the port and pushed through the tube by an air bolus or by additional medications.

Horses with lavage systems in place are typically kept in veterinary clinics for monitoring and treatment. It is possible to keep a horse with a lavage system at home if you have the appropriate resources, expertise and support system.
