What is a common cause of cicatricial entropion?

Cicatricial entropion occurs when the eyelid turns inward due to scarring or contracture of the eyelid tissue. The primary cause of this condition is trauma that results in the formation of scar tissue, which can alter the normal position and function of the eyelid. This scarring can occur from various factors, including injury, surgery, or previous infections, leading to a tightening of the eyelid skin and pulling it inward against the eyeball.

In this context, trauma leading to scar tissue formation is the most recognized and common cause of cicatricial entropion, as it directly leads to the alteration of eyelid anatomy and function. Other conditions might involve abnormal eyelid positioning, but they stem from different pathophysiological mechanisms. Understanding the relationship between trauma, scarring, and entropion is crucial in identifying and treating this condition effectively.
