Which condition may result from untreated entropion in pets?

Untreated entropion can lead to blindness in pets due to the condition causing the eyelids to roll inward. This inward rolling results in the eyelashes and skin rubbing against the cornea, leading to irritation and damage. Over time, excessive rubbing can lead to corneal ulcers, which, if not addressed, can progress to more severe ocular complications, including cataracts or complete loss of vision. The prevention of such serious outcomes makes it crucial to recognize and treat entropion promptly.
