Indian fold:The Indian fold, or internal fold, is characterised by an upper lid with its edge extending down along the inner lid. The lacrimal lake is often covered. In the Mongolian fold the edge of the eyelid is often covered by the fold, whereas in the Indian fold the edge of the eyelid itself produces the fold. Thus, the lid edge is composed of the lash-carrying section of the lid, and the eyelashes are fully visible (in difference to the Mongolian fold). This fold is particularly common among Native Americans, although those ethnic groups may show the Mongolian fold, the epicanthus, and other folds alternatively or in addition. However, in Native Americans the Mongolian fold often disappears during adult age, whereas the Indian fold does not. In some publications the Indian fold was erroneously confused with the Mongolian fold. |
