Eye ptosis, also known as blepharoptosis, is a condition where the upper eyelid sags or droops. This condition can affect one or both eyes and is most commonly caused by dysfunction of the levator muscle, but it can also result from trauma, heredity, and certain medical conditions. While eye ptosis can impact both vision and appearance, outpatient surgery often corrects the condition, enhancing both functionality and aesthetics.
Überblick
Upper eyelid drooping, referred to medically as blepharoptosis, can occur due to various factors including genetic predisposition, facial trauma, reduced skin elasticity with age, and the chronic effects of gravity. It can also be associated with certain medical disorders such as Horner syndrome, nerve palsy, eye diseases, or tumors.
- Unilateral Ptosis: When only one eyelid droops.
- Bilateral Ptosis: When both upper eyelids sag.
- Angeborene Ptosis: Present at birth, though rare.
- Erworbene Ptosis: Develops later in life.
Eye ptosis can range from mild, which may not disrupt vision, to severe, which can partially or fully obstruct the eye’s ability to see. The condition affects men and women of all ethnicities equally, though it is more prevalent among the elderly due to age-related changes in connective tissue and muscle function.
Children with ptosis are at greater risk for other eye and vision challenges, including amblyopia (lazy eye), astigmatism (blurry vision), misaligned eyes (strabismus), and double vision (diplopia).
Die Einzelheiten
Eye Ptosis Surgery & Correction
An ophthalmologist will consider several factors when determining the best treatment for eye ptosis:
- Whether the ptosis is unilateral or bilateral
- The strength of the muscles controlling the eyelid
- The eye’s range of movement
- The height of the eyelid
- The patient’s age
The primary goal of ptosis treatment is to improve vision. In most cases of severe ptosis, surgery is recommended to tighten the eyelid muscles that have become stretched or weak.
Types of Ptosis Surgery
- Externer Levator-Vorschub
- Verfahren: This common surgical technique is used when the upper eyelid crease is high, and the levator muscle functions normally but the aponeurosis (a fibrous tissue that acts as a tendon) is stretched or disinserted.
- Approach: An incision is made through the outside of the upper eyelid crease, allowing the surgeon to access and adjust the muscles and tendons.
- Vorteile: This approach is beneficial for removing excess eyelid skin if necessary and for providing a more controlled adjustment of the eyelid position.
- Internal Approach
- Verfahren: This technique addresses the fibrous connective tissue of the levator aponeurosis, tarsus, or Muller muscle without making an external incision.
- Approach: The surgeon flips the eyelid inside-out and shortens the tissues.
- Limitations: Typically used for minimal ptosis of 2 mm or less.
- Frontalis-Schlingenfixierung
- Verfahren: Recommended for cases of congenital ptosis with impaired levator function.
- Approach: The eyelid is attached to the frontalis muscle (controls eyebrow movement) using a silicone rod or similar material without making an incision.
- Adaptation: The patient learns to control the eyelids using the frontalis muscle.
- Überlegungen: Effective for severe ptosis but not advisable for those with severe dry eye syndrome or corneal sensitivity.
Surgical Considerations
- Outpatient Surgery: Most ptosis surgeries are performed on an outpatient basis with local anesthesia and oral sedatives to ensure patient comfort. General anesthesia is typically not required.
- Pre-Surgery Preparation: Patients should inform their surgeon about any medications, supplements, and herbal remedies they are taking, as these can interfere with controlling bleeding, blood pressure, and heart rate during surgery.
Risks and Precautions
As with any surgical procedure, ptosis surgery comes with risks. Patients should discuss potential complications and their likelihood with their ophthalmologist during the consultation. Understanding these risks is crucial for making an informed decision about undergoing surgery.

Abschluss
Eye ptosis can affect both vision and appearance, making it a significant concern for many individuals. Whether congenital or acquired, ptosis commonly results from issues with the levator muscle, which may fail to develop properly or become dysfunctional over time. Surgery is the primary treatment to restore function and appearance, with several approaches available depending on the specific case.
Ptosis surgeries are generally safe and effective, performed as outpatient procedures with local anesthesia. However, understanding the potential risks and discussing them with a healthcare provider is essential. Regular eye checks for children and consultation with an ophthalmologist for adults experiencing ptosis can ensure timely and effective treatment, helping to maintain both vision and quality of life.
