YOU ARE OBSERVING

Eyelid is Rolled Outward, Exposing Pink Tissue

Summary

This is a rare finding and usually results from swelling of the tissues lining the eye, the conjunctiva. This swelling can be severe enough that it rolls the eyelid outward, and exposes a rim of pink moist tissue around the eye. This is conjunctivitis, and it can be caused by trauma, foreign body, infection, tumor and many other causes. The key is identifying and treating the underlying cause.

What To Do

Given the importance of the eyelid in protecting the eye, do not allow this condition to continue or worsen over time. Look for other signs of eye injury, especially to the cornea (clear front surface). Share your findings and concerns with your vet.

Your vet will determine the nature of this condition and look for any underlying causes. Treatment will likely be aimed at the underlying causes.
Questions Your Vet Might Ask:
  • Is the horse showing signs of eye discomfort like squinting or blinking or holding the eye closed?
  • Is the horse's eye tearing or watering?
  • When did you first notice this?
  • How does it compare to the other eye?
  • What are the results of the Whole Horse Exam (WHE)?
