What Is Dermatochalasis?

With age, the eyelid skin loses elasticity and the connective tissue weakens, causing the skin to stretch and drape over the lid margin. This process is called dermatochalasis. It affects the upper lids more noticeably but can also involve the lower lids, contributing to under-eye bags.

Upper-lid dermatochalasis is one of the most common reasons patients seek oculoplastic consultation. In mild cases the concern is primarily cosmetic; in moderate to severe cases the overhanging skin impairs peripheral and superior vision.

Causes and Contributing Factors

• Natural aging and loss of skin elasticity (elastosis)
• Genetic predisposition -- some families develop dermatochalasis earlier
• Sun damage accelerating skin laxity
• Smoking, which degrades collagen and elastin
• Gravity acting on thin eyelid skin over decades
• Brow ptosis compounding the effect by pushing tissue downward

Symptoms

• Heavy, tired-feeling upper eyelids
• Skin resting on or overhanging the eyelashes
• Obstruction of the upper and lateral visual fields
• Compensatory forehead muscle contraction and brow elevation to lift the skin, causing headache or forehead fatigue
• Difficulty applying makeup or wearing glasses comfortably
• In lower-lid involvement: puffy, baggy appearance under the eyes

Diagnosis

Dermatochalasis is diagnosed clinically. The evaluation includes:

1. Measurement of excess skin: The amount of redundant upper-lid skin is pinched and measured.
2. Visual field testing: Automated perimetry is performed with the lids in their natural position and then repeated with the excess skin taped up. A significant improvement with taping confirms functional impairment.
3. Levator function assessment: The excursion of the levator muscle is measured to rule out concurrent ptosis.
4. Brow position evaluation: Brow ptosis can mimic or worsen upper-lid dermatochalasis and may require a separate brow procedure.

Surgical Treatment: Blepharoplasty

Upper blepharoplasty

The standard treatment for upper-lid dermatochalasis. An elliptical strip of excess skin -- and occasionally a strip of orbicularis muscle and herniated orbital fat -- is removed through an incision placed in the natural eyelid crease. The incision heals within the crease line and becomes nearly invisible. The procedure is performed under local anesthesia, typically in 30-45 minutes per side.

Lower blepharoplasty

Addresses excess skin and fat prolapse of the lower lids. The approach may be transcutaneous (external skin incision just below the lash line) or transconjunctival (incision inside the lid, leaving no visible scar). Fat may be removed or repositioned to smooth the lid-cheek junction.

Combined with ptosis repair

When dermatochalasis coexists with ptosis, both conditions can be corrected through the same incision in a single procedure. The levator muscle is tightened or advanced during the blepharoplasty.
