## Overview Entropion is inward rolling of the eyelid margin so that hair contacts the cornea. It is most common in newborn foals due to dehydration, prematurity, or excess skin. Adult-onset entropion is usually secondary to ocular pain (spastic entropion). Corneal ulceration is a frequent complication. ## Causes Congenital or acquired (dehydration, pain-induced spasm). ## Diagnosis Visual inspection of the eyelid position and fluorescein staining to check for corneal damage. ## Treatment Temporary tacking sutures or lubrication in foals. Treat underlying pain in adults. Surgical correction for persistent cases. ## Recovery and Prognosis Excellent in foals once corrected. Adult cases resolve when the primary ocular pain is treated. ## Prevention Prompt treatment of ocular pain and monitoring of neonatal foals.
