Clinical and ultrastructural correlation in congenital and acquired ptosis
Ophthalmic Surgery
|January 1, 1976
Abstract:
The levator superioris muscle has been studied with the light microscope and the electron microscope in congenital and acquired ptosis. Ultrastructural finding correlated closely with the clinical entities. Congenital ptosis appears to be on a myogenic basis. Acquired ptosis ultrastructurally indicates a regenerative process.
