9A03.0/H02.4 Blepharoptosis



Blepharoptosis is a condition where one or both eyelids droop and may partially or completely cover the eye. It is caused by a number of different disorders, including mechanical (trauma), neurologic (Bell’s palsy), and myogenic (myasthenia gravis).


Diagnosis of blepharoptosis requires a thorough physical examination, including inspection of the eye and eyelids.

Differential diagnosis

Differential diagnosis includes mechanical ptosis (trauma), neurologic ptosis (Bell’s palsy), and myogenic ptosis (myasthenia gravis).


Treatment of blepharoptosis depends on the underlying cause. In some cases, the eyelid droop may resolve on its own. In other cases, surgical correction may be needed.


The prognosis of blepharoptosis depends on the underlying cause. If the condition is due to trauma, the prognosis is usually good. If it is due to a neurologic disorder, such as Bell’s palsy, the prognosis is more guarded. If it is due to myasthenia gravis, the prognosis is generally good, although some patients may experience recurrent episodes of ptosis.
