Plain-English summary
Two horses developed a condition called Horner's syndrome after they received routine intravenous injections in their necks. This condition caused one horse to have a droopy eyelid and both horses to sweat on one side of their faces. Fortunately, these symptoms went away within 14 hours, and there were no signs of complications from the injections. This situation shows that Horner's syndrome can occur even after standard intravenous procedures, not just after more complicated injections. Overall, the horses recovered completely without any lasting issues.
Abstract
Horner's syndrome developed in 2 horses after routine jugular venipuncture. Signs included unilateral sweating of the face in both horses and ptosis in 1 horse. The signs resolved within 14 hours. Signs of a perivascular injection did not develop in either horse. Although Horner's syndrome has been reported after perivascular jugular injections these cases illustrate that the syndrome may develop following routine intravenous injections.
