Congenital entropion affects babies, but this is very rare. Herpes zoster ophthalmicus or HZO, an eye infection, can result in entropion. Trachoma is a disease caused by bacteria, usually spread by flies, that can cause blindness and is common in Africa. Surgeries and eye injuries such as burns can also cause entropion. Lastly, an autoimmune disease called ocular cicatricial pemphigoid can cause the eyelid to fold in on itself.
