Entropion in Horses



While the pain and soreness associated with entropion can be treated using topical ophthalmic ointments, a surgical adjustment of the eyelid(s) is the only way to correct the condition. Stitches are placed on the outside of the affected lid that pull the lid (and eyelashes) out and away from the corneal surface. This is a very simple and quick procedure that can be done on the farm. These stitches are left in for a few weeks and then removed. Once the stitches are removed, the eyelid should be trained to properly position itself outwardly. Topical antibiotic ointment should also be used during this period to help the corneal ulcerations heal.


Living and Management


While a foal has stitches placed for this condition, daily monitoring of the eye is important. You will need to check to make sure that the foal has not rubbed the stitches out and that the eyelid hasn’t become inverted again despite the stitches. Daily observations will also allow you to monitor the healing of the cornea.




Entropion cannot be prevented, as it is congenital or secondary to another disease, such as one causing severe dehydration. Luckily, it can be fairly easily corrected and has no lasting affects on the foal’s eyesight.
