Context Explanation

Entropion is a condition in which the eyelid margin turns inward. The eyelid skin and eyelashes rub against the eye’s surface, causing discomfort and irritation. The cornea (clear dome in front of the eye) is also affected in many cases. In entropion, your eyelid turns inward, causing lashes and skin to rub against the eye.

Insight Material

Learn about causes and treatment for this irritating eye condition. Entropion is an inward turning of the eyelid margin and appendages such that the pilosebaceous unit and mucocutaneous junction are directed posteriorly towards the cornea and ocular surface. It is one of the most common eyelid malpositions seen mainly in the elderly. If the edge of one eyelid turns inward (entropion), the eyelashes rub against the eye, which can lead to ulcer formation and scarring of the cornea. If the edge of one eyelid turns outward (ectropion), the upper and lower eyelids cannot meet properly, and tears are not spread over the eyeball.

Final Conclusion

An entropion is where the eyelid turns towards the eye. It causes the eyelashes to rub against the front of the eye (cornea). Entropion can cause irritation as your eyelashes rub against the eye. Left untreated, it can cause infection and lead to loss of vision. Eyelid surgery returns the eyelid with entropion to its normal position. In these drawings, the eyelid is cut away to show the appearance of a normal eyelid (top) and an eyelid turning inward (bottom).
