Clinical, biochemical and histological results of a levator muscle transposition for ptosis in Cynomolgus monkeys

Abstract

The transposition of the levator muscle of the upper lid on the frontal muscle was studied on four Macaque cynomolgus monkeys. The results indicate a re-innervation of the transposed levator muscle from nerve fibres of the frontal muscle. This operation introduces a new alternative to the treatment of ptosis with synkinesia of Marcus Gunn.
