The eyelids need to be in a normal position to ensure eye protection, for good tear production and drainage and to allow the eyelids to close properly with each blink. When the lids are malpositioned, they can be very irritating to the eye and result in tearing, pain, and chronic discharge. Entropion is a condition in which the eyelid is "turned in" toward the eye. Ectropion is a condition where the lower eyelid is "turned out" away from the eye. Both can be repaired with surgical procedures designed to return the eyelid to its natural position.
