Plain-English summary
A 5-year-old mixed-breed dog developed anisocoria, which is a condition where one pupil is larger than the other, after coming into contact with an ornamental plant called Datura stramonium. The dog's owner noticed the unusual eye appearance and took the dog to the vet. The vet confirmed that the plant caused the problem and advised keeping the dog away from it in the future. Fortunately, the dog's condition improved once the exposure was removed, and no long-term effects were noted.

Abstract
We report an unusual case of anisocoria in the dog provoked by Datura stramonium, and an experimental clinical assay to reproduce the anisocoria using simple contact with part of the plant in four healthy dogs. Any part of the D. stramonium plant produced anisocoria following simple contact with the eye.
