what is entropion
ENTROPION. Entropion is a condition in which the eyelid is rolled inward toward the eye. It can occur as a result of advancing age and weakening of certain eyelid muscles. Entropion may also occur as a result of trauma, scarring, or previous surgeries. Entropion may also occur in children. This is discussed in more detail in the pediatric section. A turned in eyelid rubs against the eye, making it red, irritated, painful, and sensitive to light and wind. If it is not treated the condition can lead to excessive tearing, mucous discharge and scratching or scarring of the cornea.
