Epithelial down growth must be avoided by a good wound closure with good cleaning of its edges. If a fistula appears in spite of those precautions, the plug graft is shown to be the most efficient treatment. If an advanced epithelial down growth is evident a large excision of the invaded tissues must be performed and a keratoplasty with repair of the area lost. An early diagnosis which imposes an urgent surgical decision is an essential point of the prognosis
