The University of Wisconsin-Madison (UW) School of Veterinary Medicine has acquired a dynamic endoscope for use in evaluating equine airway disorders, according to a posting on the school’s website. This dynamic endoscope is currently the only such tool in the state of Wisconsin, the post read.

According to the post, the dynamic endoscope attaches to the horse’s bride and saddle pad and transmits readings to a remote tablet, allowing the veterinarian to see what is happening in the animal’s airway during his normal exercise routine.

Dynamic endoscopy–in which the horse undergoes and endoscopic exam while exercising on a high speed treadmill or working under saddle–is used to diagnose airways disorders not apparent on resting endoscopy or to evaluate how a horse’s airway functions during exercise. Some anomalies that veterinarians can diagnose during dynamic endoscopic evaluations include laryngeal hemiplegia (or roaring), axial deviation (collapse) of the aryepiglottic folds, epiglottic retroversion, and pharyngeal collapse.
