Ectropion

Ectropion (Gr., from ek, 'out,' and trepo, 'I turn'), eversion of the margin of the eyelid, so that the red inner surface (conjunctiva) is exposed. It is generally caused either by chronic inflammation of the conjunctiva, or by scars in the skin near the eye, following wounds, burns, or disease. It is the converse of entropion, and like it, usually requires an operation for its cure. Recent and slight inflammatory cases, however, may yield to milder measures.
