Ptosis is a drooping upper eyelid that extends too far over the eye. It corresponds to a reversible cause of impairment of the peripheral visual field. Ptosis can be responsible for a loss of the upper visual field, but also for reading difficulties related to the worsening of the ptosis in the gaze downwards and sometimes for a decrease in visual acuity at night when the amount of light is less important. Ptosis is linked to a deficiency in the levator muscle of the upper eyelid which may be congenital or acquired. There are different possible causes of ptosis: aponeurotic, myogenic, neurogenic, mechanical or traumatic. The most frequent remains acquired aponeurotic ptosis linked to stretching or disinsertion of the levator muscle of the eyelid.
Ptosis surgery is indicated in the event of aesthetic discomfort perceived by the patient or in the event of functional discomfort with amputation of the upper visual field in the event of significant ptosis.
Treatment of ptosis is surgical. Ptosis that results in a significant upper visual field deficit or difficulty reading is considered functional.
The most frequently used procedure remains the transcutaneous fold technique allowing the repositioning of the muscle more or less associated with the excision of excess skin (dermatochalasis).
The operation takes place under local anesthesia, realized by sedation, in outpatient surgery, in the clinic, one eyelid at a time.
The first postoperative days after ptosis are marked by edema and hematoma of the upper eyelids which resolve rapidly (approximately one week). Sutures are placed and removed within 5-7 days after surgery. Ointments are applied to the scars (and in the eyes) for a month. It is advisable to avoid exposure to the sun and smoking during the healing period. The final result is obtained after one month.
