Symptoms of entropion include:
Redness and pain around the eye
Sensitivity to light and wind
Sagging skin around the eye
Excessive tearing
Decreased vision, especially if the cornea is damaged
Treatment is a simple surgery in which excess skin of the outer lids is removed. Prognosis is excellent if surgery is performed before the cornea is damaged
Upper lid entropion involves the eyelashes rubbing on the eye, but the lower lid usually has no eyelashes, so hair rubs on the eye. Surgical correction is used in more severe cases. A strip of skin and orbicularis oculi muscle are removed parallel to the affected portion of the lid and then the skin is sutured |
Hi I found this page very informative. It looks like it likely is genetic.
