Plain-English summary
This study looked at Horner's Syndrome (HS), a condition that affects horses, through both experimental cases and one natural case. In the experimental cases, HS was caused by cutting a specific nerve in the neck, while the natural case involved a 17-year-old gelding with a tumor in the chest area. Horses with HS showed signs like drooping eyelids, a smaller pupil, a sunken eye, and sweating on one side of the face, with some differences in how strong these signs were. Recognizing HS is important for understanding where problems might be in the horse's body, especially since it can be linked to serious issues like bleeding from the nose. The study highlights the need for careful observation, as some signs can be hard to notice.
Abstract
The findings in 6 experimental and 1 natural case of Horner's Syndrome (HS) are presented. The experimental cases were induced by unilateral surgical section of the cervical sympathetic trunk in the middle third of the neck. The naturally occurring case was seen in a 17 year old gelding with a mediastinal tumour. The signs of HS in these horses included ptosis, miosis, enophthalmos, hemilateral sweating and temperature increase of the face and cranial cervical region on the affected side. The intensity of these signs was variable between and within animals. Miosis, enophthalmos and temperature difference were sometimes difficult to discern. Clinically the recognition of HS is important in the localization of lesions, and when accompanied by nasal haemorrhage is highly suggestive of guttural pouch mycosis.
