In ectropia, the bottom eyelid hangs out of the eyeball, causing drying and irritation of the lower half of the eyeball and the mucosa of the bootom eyelid. In addition, ectropia can prevent the tear penetrating, which lubricate the mucosa of the upper eyelid and the front part of the eye, into the suction canal in the lower lining, so the tears fall down the cheek.
Ectropia is a commonly occurring disorder. A muscle that strains the eyelid above the eyeball weakens. This condition may also occur at any age if the cause of it is a scar on the lower eyelid or cheek which shortened or pulled the eyelid down.
If the ectropia is not treated, corneal ulcers may develop and permanently damage the cornea.
What to do?
Ectropia rarely disappears by itself, so you have to contact your doctor for tissue surgery under the eyes; this is a minor surgical procedure under local anesthesia.
