Symptoms
- Redness and pain around the eye
- Sagging skin around the eye
- Eye watering
- Decreased vision, especially if the cornea is damaged
Causes
- Congenital
- Aging creating loose skin and stretched and loose ligaments and muscles (senile entropion).
- Scarring (mechanical entropion)
- Spasm
- An eye infection called trachoma is still common in North Africa and South Asia and this can cause scarring of the inner eyelid, which may cause friction and entropion.
Treatment
Treatment is a relatively simple surgery in which excess skin of the outer lids is removed or tendons and muscles are shortened with one or two stitches. General anesthesia is sometimes used before local anesthetics are injected into the muscles around the eye. Prognosis is excellent if surgery is performed before the cornea is damaged.

Alternative techniques such as the Wyman technique focus on tightening the lower eyelid. This technique is not as effective in cases of enophthalmos.[9] Shar Peis, who often are affected as young as two or three weeks old, respond well to temporary eyelid tacking. The entropion is often corrected after three to four weeks, and the sutures are removed.[5]
