Congenital blepharoptosis, caused by levator muscle dysgenesis or the defect of the central and peripheral nerves that govern the levator muscle, is a common disease in clinical practice. The blepharoptosis not only affects the appearance, but can lead to deprivation amblyopia in severe cases which disturbs the visual function. Timely correction is, therefore, critical. The purpose of ptosis correction is to renew normal palpebral fissure height, to get rid of the interference of visual axis caused by ptosis, to pursue the good functional and cosmetic outcome at the same time. In this paper, the operation opportunity and the surgical treatments of congenital blepharoptosis were reviewed.
