This is defined as inturning of the lid margins. It can involve both the upper and lower lids. Most patients complain of tearing and redness because of irritation by the inturned lashes.
It can be congenital called epiblepharon. Most often it is present in the Oriental on the nasal half of the lower lid.This condition will most often improve as the child grows. However if symptoms persist and cause corneal damage patient will need surgery. The surgery involves the removal of a small strip of the skin and muscle on the nasal aspect. In children this procedure is carried out under general anaesthesia.
The acquired form occurs due to normal aging process called involutional entropion. The surgery is performed via an incision under the lid margin. under local anaesthesia.
Other causes can be due to chronic inflammation, infection or trauma of the conjunctiva.In this condition the conjunctiva is contracted. The surgery involved here is additional. It may require a graft to length the conjunctiva.
The lid correction has to be performed if it is causing corneal damage and also in patients before cataract surgery.
