Entropion (Eyelid edge turning inward) and Ectropion (Eyelid edge turning outward)
Entropion is a condition in which the eyelid margin and eyelashes turn inward. Ectropion is the outward turning of the eyelid edge and eyelashes. These are the most common valve deformities in clinical practice. The most common cause of these conditions is age-related deterioration of the structure of the ligaments that provide valve stability. Other causes include congenital diseases, previous surgeries, trauma-injuries, some skin diseases, radiation treatments, eyelid masses and tumors. As the lids turn inward, there will be constant irritation of the lid edge and eyelashes to the eye surface. This situation will cause patients to complain of stinging, burning, watering and redness in the eyes. As a result of constant exposure of the eye surface to this irritation, infections and a condition that can progress to eye loss may develop. If the eyelids turn outward, the surface of the eye will remain open, especially at night during sleep, which may result in drying of the surface, infections in later stages, and eye loss.
In both cases, the treatment is surgery. Although the operation can be performed under local anesthesia, general anesthesia is required in pediatric patients with congenital valve disorders. Depending on the cause and severity of the clinical picture, it may also be necessary to transport tissue from areas suitable for the eyelid. The patient is discharged on the same day.
