Congenital Abnormalities Of The Eye - Congenital Ptosis
Defination
This is a dropping of eyelid which is present at birth and which may be due to congenital third nerve palsy
Signs and symptoms
The main symptom of ptosis is the droopy eyelid itself
Causes
Third cranial nerve palsy
Marcu Gunn jaw- winking syndrome
Horner syndrome
Blepharophimosis syndrome
Birth trauma
Risk Factors
Nerve damage in the eye muscles
Horner's syndrome
Neurological conditions
Eyelid tumors, cysts, or swelling
Muscular problems
Pathophysiology
In most cases of congenital ptosis, a droopy eyelid results from a localized myogenic dysgenesis.
Rather than normal muscle fibers, fibrous and adipose tissues are present in the muscle belly, diminishing the ability of the levator to contract and relax
The eyelids are elevated by the contraction of the levator palpebrae superioris
Therefore, the condition is commonly called congenital myogenic ptosis
