Peterson & Smith now has a new dynamic respiratory endoscope to use for obtaining under tack images of a horse’s pharynx and larynx. Unlike scoping on a treadmill this endoscope is worn on the saddle pad of the horse while it is 
training on the track under natural conditions. The images are transferred to a computer for complete analysis when the exam is over, but some of the video can be viewed on a wireless monitor while the horse is training as long as the horse is not too far away.
This scope will specifically be useful for horses that either make an abnormal noise or have exercise intolerance – and routine endoscopy at rest or 
following training either yields no answer or an incomplete answer. While it will most commonly be done on race horses it will have application to all types of performance horses. One of the most common issues this technology will confirm is dorsal displacement of the soft palate. In addition, it can be used for problems that cannot be diagnosed without endoscopy during exercise: mild paralysis of an arytenoid (flap), collapse of the arytenoepiglottic (AE) folds, collapse of the pharynx, and retroversion of the epiglottis.
