Vasomotor rhinitis with headshaking in a pony.
Abstract: VASOMOTOR rhinitis (VR) is a chronic, non-seasonal disease of the nasal mucosa of man with symptoms including profuse bilateral watery nasal discharge, sneezing, nasal airflow obstruction, nasal pruritus and loss of smell. The disease is believed to result from nasal hyper-reactivity to exogenous and endogenous stimuli including temperature and humidity changes, odours and physical or emotional stress (Groves, Gray, Downton and Blau 1985). Although the aetiology of this non-infectious and non-allergic rhinitis is not completely understood, it is believed to be largely due to an imbalance in the autonomic control of nasal mucosal function (Mayeux et al 1986; Jones and Lancer 1987). VR is a common disease in man, accounting for approximately half of chronic non-seasonal rhinitis cases (Jones and Lancer 1987) with up to 18 per cent of the general population being subject to some form of chronic rhinitis (Meltzer 1988); most commonly a seasonal nasal allergic rhinitis, ie hay fever. There appears, however, to be just a single suspected case of equine VR recorded in the literature (Lane and Mair 1987). The present report describes a case of confirmed VR which differs in several important respects from the previously reported case. The effects of various medications on the clinical signs are also described.

This research paper discusses a case of Vasomotor Rhinitis (VR), a chronic, non-seasonal nasal disease, in a pony. The report illuminates the unique characteristics of this specific case, comparing it to previous ones in the literature, and evaluates the impacts of different medications on the observed symptoms.
Understanding Vasomotor Rhinitis
- VR is a disease that affects the nasal mucosa, leading to multiple symptoms like copious bilateral nasal discharge, sneezing, obstructed nasal airflow, nasal itching, and loss of smell.
- The disease manifests due to hyper-reactivity of the nasal area to various stimuli. These include changes in temperature and humidity, different odours, and physical or emotional stress.
- The exact cause of this non-infectious and non-allergic rhinitis remains poorly understood, but experts attribute it largely to an imbalance in the autonomic control of nasal mucosal function.
- VR is prevalent in humans, accounting for about half of chronic non-seasonal rhinitis cases, and affecting up to 18% of the general population in some form of chronic rhinitis. The most common form of this is seasonal nasal allergic rhinitis, commonly known as hay fever.
Vasomotor Rhinitis in Equines
- Despite its widespread prevalence in humans, VR’s occurrence in horses is limited. Only one suspected case of equine VR has been recorded in medical history to date.
- This research presents a confirmed case of equine VR, unique in several critical characteristics when compared to the supposedly only other known case.
Exploring Treatment Options
- The research went beyond mere diagnosis to evaluate the impact of various medications on the clinical signs associated with equine VR.
