What underlying problem usually contributes to involutional entropion?

Involutional entropion is primarily associated with a combination of age-related changes that occur in the eyelid structure. As individuals age, the tissues that support the eyelids, including the muscles and connective tissues, undergo degeneration. This gradual deterioration leads to a loss of elasticity and strength, which can cause the eyelids to turn inward. The most common factors contributing to this condition include a weakening of the eyelid muscles and the loss of structural support, causing the eyelids to change position and no longer maintain their normal outward orientation.

Involutional entropion is mainly observed in older adults, making age a significant risk factor. While genetic conditions, traumatic injuries, and infections can lead to other types of entropion, they are not the primary contributors to the involutional variety. Understanding that involutional entropion is closely tied to the natural aging process helps in addressing and managing the condition appropriately.
