What does the term "entropion" refer to in veterinary medicine?

Entropion refers to a condition in which the eyelids, particularly the lower eyelid, roll inward against the eyeball. This inward rolling can cause irritation to the cornea and conjunctiva, leading to discomfort, excessive tearing, and potential damage to the eye itself if left untreated. The term is derived from the Greek word "entropion," meaning 'to turn in.'

This condition is often seen in certain dog breeds with loose eyelid skin or those who have conformational issues. Treatment typically involves surgical correction to repair the eyelid position and relieve the pressure on the eye, thus protecting it from further damage and alleviating the associated pain and discomfort. Understanding entropion is essential for recognizing signs of ocular distress in animals and ensuring timely medical intervention.
