What condition is described by the eyelids being turned outward?

The condition characterized by eyelids being turned outward is known as ectropion. In ectropion, the lower eyelid (and sometimes the upper eyelid) is displaced away from the eyeball. This leads to exposure of the conjunctiva, which can cause discomfort, dryness, and an increased risk of infection. It is often caused by aging, muscle weakness, or scar tissue from previous surgery or trauma. Ectropion can result in tearing since the eye does not drain tears effectively when the eyelid is not in its normal position.

In contrast, ptosis refers to the drooping of the eyelid, which does not involve outward turning. Entropion is the opposite of ectropion, where the eyelid turns inward, causing the eyelashes to rub against the eyeball, which can result in irritation and potential corneal damage. Blepharitis is an inflammation of the eyelid margins, which can cause redness and irritation but does not specifically describe a position change of the eyelids like ectropion does. Understanding these distinctions makes it clear why ectropion, with its specific presentation of outwardly turned eyelids, is the correct answer.
