What is
Congenital Eyelid Drooping?

Ptosis is referred to as the drooping of the eyelid. Normally, the position of the upper eyelid is 0.5 to 1.0 mm below the upper edge of the cornea. If the upper eyelid is lower than normal, it is considered to be ptosis. If ptosis is present at birth or within the first year of life, it is called congenital ptosis.

In most cases, congenital ptosis occurs alone and is not related to any systemic disease. There is no gender difference in congenital ptosis, and it can affect one or both eyes.

The causes of
Congenital Eyelid Drooping

In many cases of congenital ptosis, there is no known cause, but in some cases, it occurs due to heredity (autosomal dominant). Histologically, it has been revealed that the levator muscle and aponeurosis tissues in patients with congenital ptosis are replaced by adipose and fibrous tissues.

Congenital ptosis exists from infancy, which can lead to a condition called "amblyopia" where vision does not develop. Amblyopia can occur due to visual impairment caused by the obstruction from ptosis, or it can result from astigmatism caused by corneal distortion, leading to visual impairment and consequently amblyopia.
Amblyopia can be an indication for early surgery. Also, the appearance in cases of ptosis is often not aesthetically pleasing, and surgery is recommended in such cases.

Treatment methods
for Congenital Eyelid Drooping

If there is a possibility
of amblyopia,
early surgery is necessary.

Not all patients with congenital ptosis require surgery, but it is necessary to carefully monitor children for the possibility of amblyopia.

Since amblyopia is less likely to be reversible after the age of 7 to 10, it is very important to perform surgery before this age to maintain vision.

Diagnosis of the presence or absence of amblyopia is required between the ages of 3 and 7.

Also, since vision tests become possible at the age of 3 to 4 years, diagnosis of amblyopia cannot be performed until after this period.

Therefore, it is considered appropriate to diagnose the presence or absence of amblyopia during the period from 3 to 7 years, and surgery should be performed if amblyopia is observed or suspected (except in cases of severe ocular torticollis).

Furthermore, ptosis can have a negative impact on development due to appearance issues.

Surgery for Congenital Eyelid Drooping

Surgical Methods for Congenital Eyelid Drooping

In congenital ptosis, due to its physical, functional, and psychological impacts, surgery is recommended at some point, using one of various methods. The method of surgery varies depending on treatment goals, the underlying diagnosis, and the degree of levator function. While the main purpose of the surgery is functional, improving the appearance by making the eyelid shape and the width of the double eyelid symmetrical is also a goal.

Surgery for congenital ptosis can be performed at any age depending on the severity of the condition, but early surgery may be necessary, especially in cases of severe amblyopia or ocular torticollis. In severe cases of ocular torticollis, the extreme head-up posture can disrupt body balance and delay development during infancy and early childhood. If early surgery is not necessary, it is usually performed after the age of 3 or 4. Waiting until this age allows for more accurate measurements before surgery.

Regardless of the surgical technique used, it may become difficult to close the eyes, but this is generally not a problem until the 20s or 30s as the corneal surface is relatively resistant to dryness. Conversely, performing surgery in middle and older age can lead to corneal surface injuries, causing pain and foreign body sensation, and sometimes corrective surgery is required.

1.Levator muscle resection

This surgery involves incising the double eyelid area to shorten the complex of the levator aponeurosis and Müller’s muscle. The skin incision is made so that it is hidden behind the original double eyelid or a newly created double eyelid.

Indications:

To perform levator shortening, moderate levator function is necessary. If the levator function is more than 4mm but less than 6mm, a levator resection of more than 22mm is recommended. If the levator function is between 6mm and 8mm, the resection should be 16mm to 18mm. If levator function exceeds 8mm, a levator resection of 10mm to 13mm is required. If levator function is less than 4mm, or if there is an upward movement impairment, there may not only be insufficient eyelid elevation, but there is also a significant risk of severe corneal injury.

Individuals with a weak Bell's phenomenon (upward movement of the eyeball when the eyes are closed), decreased corneal sensitivity, or reduced tear production may be at risk of developing corneal abrasions.

Surgical outcomes:

Patients may be unable to close their eyelids during sleep for several weeks to months after surgery. Although the issue of eyelids remaining open during sleep improves over time, some degree of it may persist.

2.Frontalis Sling Surgery

Indications:

This surgery is primarily indicated for individuals with extremely weak eyelid-lifting muscles (mainly congenital).

Surgical Method:

This procedure connects the eyebrow to the eyelid, allowing the patient's eyelid to be lifted through the elevation of the eyebrow. In cases of severe unilateral congenital ptosis, the surgery may be performed bilaterally to achieve symmetry.

Materials used can include the patient’s own fascia lata, fascia lata from a tissue bank, non-absorbable suture materials (such as Prolene and nylon), silicone bands, silicone rods, and Gore-Tex sheets.

Individuals with a weak Bell's phenomenon (upward movement of the eyeball when the eyes are closed), decreased corneal sensitivity, or reduced tear production may be at risk of developing corneal abrasions.

Surgical Outcomes:

Patients may be unable to close their eyelids during sleep for several weeks to months after surgery. Although the issue of eyelids remaining open during sleep improves over time, some degree of it may persist.

3.Müller’s Muscle Tucking or Resection

This surgery is chosen when there is a good response to phenylephrine in the eyelid.
Marks are made on the conjunctiva and Müller's muscle, and the tissue is sutured with clamps. The tissue is then excised. Afterwards, the conjunctival layer is closed.

This procedure is not commonly performed in cases of congenital ptosis, but its use is well-documented, and recent literature has highlighted its increased usefulness.

Complications of Congenital Eyelid Drooping Surgery

The complications associated with surgery for the correction of congenital ptosis include the following:

• Scarring and granuloma at the incision site
• Asymmetry of eyelid shape
• Corneal abrasion and dry eye due to overcorrection
• Need for revision surgery due to undercorrection
• Exposure of materials
• Infection

Prognosis for Congenital Eyelid Drooping Surgery

Repairing congenital ptosis can result in excellent functional and cosmetic outcomes.

With meticulous follow-up and treatments such as eye patches, amblyopia can be treated.

Among patients who undergo surgery, more than 50% may require reoperation within 8 to 10 years after the initial surgery.

Recurrence Cases in Congenital Eyelid Drooping Surgery

Patients with congenital ptosis treated at our clinic are often those who have had unsuccessful surgeries or recurrences at other hospitals. There is a high likelihood of improvement with additional surgery if a recurrence occurs.

If you are considering surgery, we will check which surgical method was previously performed and the current extent of corneal damage, and choose the appropriate surgical method accordingly.

About cases of congenital ptosis:

Case 1:”Revision surgery after previous surgery for left congenital ptosis at another hospital”

20’s female.
She had undergone two surgeries at a local university hospital for left ptosis, but as the eyelid did not lift, she came to our clinic.

• 

  Before surgery

  The condition is left congenital ptosis. The left has ptosis, and the right has skin laxity, resulting in a significant difference in the shape of the eyelids between the two sides.

• 

  3 months after surgery

  After the surgery, the width of the double eyelid and the degree of eye-opening are almost the same on both sides. The difference between the left and right is hardly noticeable now.

About treatment details

• 

  Before surgery

  Her eyes have a somewhat dark impression due to ptosis.

• 

  3 months after surgery

  Just by curing the droopy eyelid, we were able to create this brighter impression.

Case 2. 30s female, “Corrective surgery after surgery at another hospital for left congenital ptosis”

30’s female.
She came to our hospital after one surgery at a university hospital and one surgery at a different large hospital for her left congenital ptosis without improvement.

• 

  Before surgery

  Due to a left congenital ptosis, the dark eye is underexposed and somewhat dark. 2 major hospitals performed surgery, but the elevation was inadequate.

• 

  3 months after surgery

  After the surgery, the width of the eyelid and the degree of widening of the eyelid are almost the same on the left and right sides. The difference between the left and right sides is almost imperceptible.

About treatment details

• 

  Before surgery

  Her eyelids are drooping, so she looks like she has a gloomy expression.

• 

  3 months after surgery

  The asymmetry between the eyes has been corrected, and the double eyelid lines have become clean, making her eyes look very beautiful.

We perform over 5,000 ptosis surgeries annually, and as a result, we often take on cases that were unsuccessful at other institutions.

The outcomes of the surgeries vary by doctor, and in most cases, we are able to improve conditions even for patients whose previous surgeries at other institutions were unsuccessful. We encourage you not to give up and to consult with us.

Side effects, risks, and precautions of ptosis treatment

• The surgery is primarily performed under local anesthesia to check the shape of the eyelid during the procedure, but general anesthesia may be used depending on the situation, such as in children.
• Sedatives may be used before surgery to reduce the sensation of pain.
• When surgery is performed under local anesthesia, severe pain may be experienced. If the pain is severe, it can be managed by adding more anesthetic or administering pain relievers.
• People who have undergone multiple surgeries tend to experience more severe pain.
• The surgery is performed to minimize asymmetry as much as possible, but complete symmetry cannot be achieved. If there is a significant difference between the left and right sides after surgery, additional suturing or reoperation may be required.
• Scars gradually become less noticeable after surgery, but scars may remain visible or develop into keloids.
• If the wound dehisces after surgery, additional suturing may be necessary.
• Orbital cellulitis can occur due to infections.
• If sedatives are used during the surgery, complications such as hypotension, bradycardia, and respiratory depression may occur.
