Causes of congenital blepharoptosis

Congenital blepharoptosis is caused by genetic factors, nervous system diseases, muscle system diseases, etc.

1, genetic factors

patients due to genetic factors may lead to congenital blepharoptosis, usually autosomal dominant or recessive inheritance.

2, nervous system diseases

patients due to nervous system development disorders lead to oculomotor nerve paralysis, resulting in congenital blepharoptosis.

3, muscle system diseases

patients due to levator muscle dysplasia, muscle weakness, muscle fiber contraction or relaxation dysfunction and other muscle system diseases, may cause congenital blepharoptosis.
