The epicanthic fold is a skin fold of the upper eyelid that covers the inner corner of the eye. This feature is commonly found in various populations, particularly among individuals of East Asian, Southeast Asian, and Native American descent. It can give the eyes a distinct appearance and is often associated with certain genetic traits. This fold is a normal anatomical variation and does not affect vision or eye function. The presence of the epicanthic fold can be influenced by genetic factors and is part of the diverse range of human physical characteristics.
