What is ptosis?
Eyelid ptosis is the drooping of the upper eyelid. It usually occurs because of dysfunction of the levator muscle, due to degenerative or congenital causes.
An eyelid with ptosis
What causes it?
Aging is the main cause of ptosis. There are different types of ptosis:
- Aponeurotic ptosis: this is the most common. It is caused by aging of the eyelid muscles and loosening of the levator muscle, causing the eyelid to droop.
- Neurogenic ptosis: an abnormality characterised by a lack of nerve stimulation in the muscle. It usually appears in children (Marcus Gunn syndrome).
- Mechanical ptosis: this occurs when there is a cyst or tumour in the upper eyelid causing "mechanical" drooping.
- Myogenic ptosis: the upper eyelid’s levator muscle does not work as it should, which means that the eyelid cannot remain in its normal position.
How can it be prevented?
Ptosis cannot be prevented, but it can be easily detected in its early stages. It is also possible to act before the visual field becomes affected and before the unsightly effect worsens. Correction prevents torticollis and neck pain, as well as discomfort associated with this dysfunction.
There are different symptoms associated with ptosis:
- The upper eyelid droops and partially or completely covers the eye
- The visual field is reduced
- The need to tilt your head back or lift your eyelid with your finger to be able to see
The treatment for ptosis is surgery. The aim of surgery is to repair the tendon that lifts the eyelid or enable the muscle to recover its usual tone. At IMO, various techniques are used to correct ptosis, the choice of one procedure or another depends on the characteristics of each case. These procedures are performed without visible incisions and with minimally invasive techniques.
