The child had salivation, and ptosis of both eyelids.
It was doubtful in this case whether the ptosis depended on injury to the nerve of supply, or on laceration and fixation of the levator palpebræ superioris.
The movements of the eyeball are restricted in a varying degree, and ptosis often results from paralysis of the levator palpebræ superioris.
Ptosis and lateral squint, with a fixed and dilated pupil, indicates pressure on the oculo-motor nerve of the same side.
The most prominent symptoms of complete paralysis are ptosis or drooping of the upper eyelid, lateral strabismus, and slight downward rotation of the eye with diplopia.
This operation is performed for cases of ptosis in which there is partial or complete loss of upward movement of the lid.
In cases of congenitalptosis the superior rectus is not infrequently absent or imperfectly developed, as is shown by the defective upward movement of the eye.
In the majority of the cases of congenital ptosis the levator palpebræ is completely absent, as shown by the want of upward movement in the lid, and it is for this condition that one of the operations of this type is performed.
Another somewhat hypothetical objection is that during sleep the eyelids are rolled upwards by the superior recti so that the lids are slightly open, but this occurs in almost all successful ptosis operations.
In wounds of the upper lid care should be taken to suture the levator palpebræ, if divided, as otherwise traumatic ptosis may result.

The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "ptosis" in a variety of sentences. We hope that you will now be able to make sentences using this word.
