Epicanthus

Epicanthus is a skin fold of the upper eyelid, from the medial canthus, covering the inner corner (canthus) of the eye. It is often associated with a broad nasal bridge and is common in children with Down Syndrome and other genetic disorders.

Causes

Epicanthus is a normal finding in many populations, including Asians and Native Americans. It can also be associated with several genetic conditions, including:

• Down Syndrome
• Fetal Alcohol Syndrome
• Turner Syndrome
• Phenylketonuria
• Williams Syndrome

Diagnosis

Diagnosis of epicanthus is typically made through a physical examination. The doctor may also ask about any family history of genetic disorders. In some cases, genetic testing may be recommended.

Treatment

Treatment for epicanthus is not typically necessary unless it is causing vision problems. In some cases, surgery may be recommended to reduce the appearance of the fold.
