Entropion and Ectropion
When the lower eyelid turns outward, this condition is called ectropion. When the lid turns inward, this is called entropion.
When someone experiences entropion, the eyelid skin and eyelashes rub against the eye, leading to excessive tearing, mucous discharge as well as crusting of the eyelid and a general uncomfortable feeling that something is in the eye. This condition can also affect vision. In ectropion the lid sags away from the eye and again, the eye tears. Surgery is helpful in correcting these malpositions.
