Third eyelid cartilage eversion in an adult mare.

Abstract: To describe the first report of third eyelid cartilage eversion in an adult American Quarter Horse mare. Methods: A 22-year-old American Quarter Horse mare presented to the University of Missouri Veterinary Health Center Equine Hospital for a 2-week history of a third eyelid cartilage abnormality of the left eye with no known recent trauma. Complete ophthalmic examination revealed third eyelid cartilage eversion of the left nictitans. The abnormal scrolled cartilage was surgically excised using a handheld cautery unit and submitted for histopathologic evaluation. Results: Histopathologic findings displayed normal third eyelid cartilage, without evidence of neoplasia or inflammation. Mucosal hyperplasia and increased vascularity of the submucosa were observed. The horse healed well after electrocautery excision and normal third eyelid conformation was restored. Conclusions: To the authors' knowledge, this is the first report of an acquired, presumed spontaneous, third eyelid cartilage eversion in a horse.

This research article discusses the first recorded case of a third eyelid cartilage eversion in an adult American Quarter Horse mare, with no known recent trauma prompting the abnormality. The research further elucidates the surgical procedure employed to correct the eversion and the subsequent healing process, which led to the restoration of the mare’s third eyelid to its normal state.

Research Overview

The horse that was the focus of this research was a 22-year-old American Quarter Horse mare, which was brought to the University of Missouri Veterinary Health Center Equine Hospital for a two-week history of a third eyelid cartilage abnormality in the left eye. There was no recent trauma that could have been the trigger for this abnormality.

  • A full-length ophthalmic examination revealed an eversion of the third eyelid cartilage of the horse’s left nictitans.
  • The irregularly scrolled cartilage was surgically removed using a handheld device designed for cauterisation.
  • The excised tissue was then submitted for histopathologic evaluation.

Results of the Examination

The histopathologic tests of the removed cartilage didn’t reveal any signs of neoplasia or inflammation. However, the tests did confirm that there was mucosal hyperplasia and an increase in the vascular nature of the submucosa.

  • The horse healed well after the electrocautery excision, and the normal conformation of the third eyelid was restored successfully.

Conclusion

In conclusion, this report brings forth the never-before-documented case of an acquired (and presumably spontaneous) third eyelid cartilage eversion in a horse. The research also discusses the effectiveness of electrocautery surgery in treating such a condition.
