Eyelid and Ptosis

Ptosis refers to drooping of an upper eyelid of one or both eyes. The droop may be barely noticeable or the lid can descend over the entire pupil, obstructing vision. Ptosis can affect both children and adults, but usually occurs because of aging. In adults, the tendon of the eyelid lifting muscle becomes loose, and the eyelid rests at a lower position than before. In children, ptosis can be present at birth, due to a weak muscle, and even mild amounts of asymmetric ptosis can cause permanent vision loss called amblyopia. Surgery to tighten the muscle tendon can be performed either through incisions under the eyelid, or externally through the skin.


Dermatochalasis is a condition where the skin between the eyebrow and the eyelash line begins to hang down over the lashes and in advanced cases, obstructs vision. Blepharoplasty surgery removes the redundant skin, improving vision and often appearance in these patients. Due to the cosmetic enhancement with removing this excess skin fold, blepharoplasty can also be performed on milder cases as a non-medical procedure.

Ectropion and Entropion are different types of eyelid malpositions that are typically caused by laxity of the eyelid tissues from aging. When the eyelid margin and lashes rotating away from the eye surface, this results in ectropion. When the lid margin and lashes rotate towards the eye surface this is called and entropion. Surgery is typically required to tighten and reposition the eyelids if the ocular surface is not adequately protected, or the eyelashes begin to irritate the cornea.

Many Asian children are born with a condition called epiblepharon, a form of entropion, where the lack of an eyelid crease causes the eyelashes to touch the cornea on either up or downgaze. Although most of these children grow out of this condition and only require topical lubrication, some require either upper or lower eyelid blepharoplasty surgery to both reduce astigmatism progression as well as corneal scarring.

Reconstruction surgery following Mohs excision
Although eyelid tumors rarely cause mortality, their excision can often present challenges for the patient. Reconstruction of the remaining tissues must both maintain good protection of the eye surface, while also functioning to permitting good vision. Dr Chen also appreciates the importance of the emotional and aesthetic functions of these eyelid tissues during reconstructive planning.
