What might cause palpebral slant-eye?
A palpebral slant, as well as a small fold of skin known as the epicanthal fold are normal in people of Asian descent. In others, it may be a sign of certain disorders present at birth, including:
- Fetal alcohol syndrome (FAS)
- Down syndrome
- Other genetic disorders
How can it be treated?
If you are of Asian descent and have palpebral slant-eye, no action is needed. This is completely normal.
When should you seek medical attention?
If a child is born with palpebral slant-eye and has other symptoms that may be indicative of a genetic condition, the doctor will likely conduct additional testing to determine an appropriate diagnosis and treatment.
