Abstract
Unilateral Congenital Blepharoptosis Associated with Ipsilateral Multiple Congenital Anomalies in 2 Cases
Highlights
Ptosis, which was formerly called congenital ptosis, is the result of an isolated dystrophy of the levator muscle affecting both contraction and relaxation of the fibers
One large-scale epidemiological data from the Section of Ophthalmic Genetics in China reported the prevalence of congenital ptosis in population was 0.18% (1:552) [3]
The patients with congenital ptosis come to the doctors mainly for appearance and vision-development reason
Summary
Ptosis, which was formerly called congenital ptosis, is the result of an isolated dystrophy of the levator muscle affecting both contraction and relaxation of the fibers. In 25% of the cases, the superior rectus muscle shares the same dystrophic changes as the levator, resulting in weakness of upgaze [1]. The extraocular muscles were derived from the mesoderm since the fifth embryonic week, while the levator palpebrae superioris muscle was differentiated from the superior rectus at the seventh embryonic week [2]. The patients with congenital ptosis come to the doctors mainly for appearance and vision-development reason. There may be some abnormalities of other organs during the embryonic development. Two cases of ptosis with special clinical presentations reported here seem to support this point of view
