It is also possible for a patient to develop ptosis as a result of an initial eyelid surgery operation. Both require eyelid revision surgeries. Since ptosis patients need correction of delicate anatomical tissues and structures, eyelid revision surgery on ptosis patients is considered one of the more difficult surgical procedures to perform.

Also specific to myasthenia gravis is the fact that coldness inhibits the activity of cholinesterase, which makes it possible to differentiate this type of ptosis by applying ice onto the eyelids. Patients with myasthenic ptosis are likely to experience a variation in the drooping of the eyelid at different hours of the day.
A chest CT-scan showing a thymoma (red circle) Photograph of a person showing right partial ptosis (left picture), the left lid shows compensatory pseudo lid retraction because of equal innervation of the m. levator palpabrae superioris (Hering's law of equal innervation): Right picture: after an edrophonium test, note the improvement in ptosis.
The most common strabismus finding is large angle exotropia which can be treated by maximal bilateral eye surgery, but due to the progressive nature of the disease, strabismus may recur. [14] Those that have diplopia as a result of asymmetric ophthalmoplegia may be corrected with prisms or with surgery to create a better alignment of the eyes.
Blepharophimosis, ptosis, epicanthus inversus syndrome (BPES) is a rare medical anomaly characterized by the conditions it is named after: blepharophimosis, ptosis and epicanthus inversus. There are two types; type 1 is distinguished from type 2 by including the symptom of premature ovarian insufficiency (POI) in females, which causes ...
Blepharophimosis forms a part of blepharophimosis, ptosis, epicanthus inversus syndrome (BPES), also called blepharophimosis syndrome, which is an autosomal dominant condition characterised by blepharophimosis, ptosis (upper eyelid drooping), epicanthus inversus (skin folds by the nasal bridge, more prominent lower than upper lid) and telecanthus (widening of the distance between the inner ...
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.

This possibility should be considered in patients who have fluctuating vision despite well-healed corneas following keratorefractive surgery. Coma (a third-order aberration) is common in patients with decentred corneal grafts , keratoconus , and decentred laser ablations.
