What is the term for the condition where the eyelid turns outward leaving the inner eyelid surface prone to irritation?

The correct term for the condition where the eyelid turns outward, exposing the inner eyelid surface and making it susceptible to irritation, is ectropion. This condition can cause discomfort and may lead to excessive tearing or dry eyes due to the lack of proper eyelid coverage. The outward positioning of the eyelid prevents it from effectively keeping the surface of the eye moist and protected, which can lead to irritation and other complications, such as conjunctivitis.

Entropion, on the other hand, is the condition where the eyelid turns inward, causing the lashes to rub against the surface of the eye, leading to irritation and potential corneal damage. Blepharitis refers to inflammation of the eyelids, which can be caused by various factors, including skin conditions or bacteria. Ptosis is the drooping of the upper eyelid, which can affect vision but does not involve the eyelid turning outward. Understanding these distinctions helps in accurately identifying and describing eyelid conditions.
