Negroid fold:The laternal Negroid fold (better: laternal external fold) appears when the upper and lower eyelid at the outer edge of the eye do not meet in a usual way, but instead the upper eyelid extends towards the cheeks. Thus, the upper lid covers a small part of the lower eyelid as well as the outer angle of the eye. This causes a flat, often pleasant-looking area above the eye-angles. Another variation of the external fold, the medial external fold (or tarsal fold), shows the same pattern, but at the inner angle of the eye. These traits are common in Sub-Saharan Africa, but they also appear more sporadically in Europe and Native America. |
