Ptosis (Drop Eyelid)
The eyelid normally covers the pupil (cornea) by 2mm, and covering the eyelid by more than 2 mm is called ptosis.
Ptosis can be congenital or may occur later on. ptosis seen from birth is due to insufficient development of the muscle that needs to open eyelid, it can be seen unilaterally or bilaterally. , in this case it is important whether the droopy eyelid prevents vision, because the development of vision in children continues after birth. /strong>what causes it.
These children need surgery, if the degree of ptosis does not prevent their vision, they should be treated with surgery before they start school. One third of these children may need glasses with droopy eyelids. If the need for glasses is not met, may be laziness.
If ptosis obstructs the visual axis, the surgical method specified as frontal suspension is applied using special silicone materials, and in older children and adults, the operation is performed according to muscle function.
In patients with good muscle function, muscle-strengthening surgery is planned by intervening the muscles. In adult patients with weak muscle function, frontal suspension can be applied with silicone straps or by using muscle sheath fibers from the leg.
droopy eyelids in adults; It may be due to nerve palsies, trauma, muscle diseases (such as myasthenia gravis), age-related changes in the muscle that opens the eyelid, in these cases, treatment should be done for the cause. .
In patients with droopy eyelids due to muscle diseases, treatment for the disease can correct droopy eyelids, and in age-related changes, improvement can be achieved by strengthening surgeries for the muscle that lifts the eyelid.
Ptosis (Drop Eyelid) Surgery
In eyelid drooping surgery, an evaluation is made according to the strength of the muscles that lift the eyelid. If the strength of the muscle is weaker than normal, surgery is planned accordingly.
We have certain values when determining muscle strength. Between these values, the decision is made according to the strength of the muscle.
For example, between 0 and 4 ml, 4-8 ml, 8-12 ml and over 12 ml, the muscle that lifts the eyelid, surgery planning and classification is made accordingly.
In individuals with weak muscle strength, that is, individuals with 4 ml or less, the success of a surgery performed on muscle strength is very poor. Therefore, it is not correct to intervene in the muscle that lifts the eyelid in such patients.
It is more appropriate to use an external material or materials taken from the autogenous body to lift the muscle. low eyelid can be removed by using external silicone materials as external materials.
However, eyelid aesthetics can be performed by using the fascialata tendon, which is mostly taken from the leg as autogenous materials. Apart from this, if the muscle function is above 4 ml, interventions to the muscle will be appropriate.
We call these rabils levator procedures. They are muscle-strengthening procedures. The factor affecting the success of the surgery is the strength of this muscle.
What are the Risk Factors for Ptosis (Drop Eyelid)?
One of the most important risk factors that will cause the formation of ptosis is the use of contact lenses. The use of contact lenses can damage the muscle that lifts the eyelid over time and cause ptosis.
Again, excessive rubbing of the eyelid may cause the muscle that lifts the eyelid to separate from the main attachment point over time.
Eyelid drooping can be seen after infections and conjunctival inflammations. In this way, there may be ptosis risk factors.
