When to Contact a Medical Professional
This trait is usually found before or during the first well-baby exam. Call your health care provider if you notice epicanthal folds on your child's eyes and the reason for their presence is unknown.
What to Expect at Your Office Visit
The doctor or nurse will examine the patient and ask questions about the medical history and symptoms. Questions may include:
- Do any family members have Down syndrome or other genetic disorder?
- Isthere a family history of intellectual disability or birth defects?
A child who is not Asian and is born with epicanthal folds may be examined for additional signs of Down syndrome or other genetic disorders.
