Other causes of ptosis include eyelid neoplasms, neurofibromas or cicatrization after inflammation or surgery. Mild ptosis may occur with aging. A drooping eyelid can be one of the first signals of a third-nerve palsy resulting from a cerebral aneurysm that is otherwise asymptomatic, a condition known as oculomotor nerve palsy.
Oculomotor nerve palsy or oculomotor neuropathy [1] is an eye condition resulting from damage to the third cranial nerve or a branch thereof. As the name suggests, the oculomotor nerve supplies the majority of the muscles controlling eye movements (four of the six extraocular muscles, excluding only the lateral rectus and superior oblique ).
The ptosis of Horner syndrome can be quite mild or barely noticeable (partial ptosis). [7] When anisocoria occurs and the examiner is unsure whether the abnormal pupil is the constricted or dilated one, if a one-sided ptosis is present then the abnormally sized pupil can be presumed to be on the side of the ptosis.

Inverse Marcus Gunn phenomenon is a rare condition [5] that causes the eyelid to fall upon opening of the mouth. In this case, trigeminal innervation to the pterygoid muscles of the jaw is associated with an inhibition of the branch of the oculomotor nerve to the levator palpebrae superioris, as opposed to stimulation in Marcus Gunn jaw-winking.
Ptosis (drooping eyelid) is when the upper eyelid droops or sags due to weakness or paralysis of the levator muscle (responsible for raising the eyelid), or due to damage to nerves controlling the muscle. It can be a manifestation of the normal aging process, a congenital condition, or due to an injury or disease.
In more extreme cases, additional intervention such as botulinum toxin injection and strabismus surgery, might be required to rebalance the actions of the extraocular muscles. [5] This would improve the alignment of the eyes when they are in primary position. [5] Similarly, surgical correction can be performed on individuals with severe ptosis. [5]
Blepharoplasty is generally a relatively safe surgery, but possible complications include hematoma/ecchymosis, lagophthalmos (incomplete or abnormal closure of the eyelids), ptosis (drooping of the upper eyelid), scarring, dry eyes, orbital hematoma/compartment syndrome, lymphedema, and ocular motility disorders. [13]
It may begin at any age and progresses over a period of 5–15 years. [1] The first presenting symptom of ptosis is often unnoticed by the patient until the lids droop to the point of producing a visual field defect. Often, patients will tilt the head backwards to adjust for the slowly progressing ptosis of the lids.
