Asian Double Eyelids vs. Caucasian Double Eyelids

When we talk about upper eyelid fold or upper eyelid crease in Asians, we are referring to double eyelid fold or double eyelid crease. We have discussed different types of Asian double eyelid fold or Asian double eyelid crease—such as infolds and outfolds. Yet when we compare to upper eyelid fold or crease in Caucasians, there are two significantly different types of upper eyelid folds. One is a typical fold that is similar to Asian double eyelid fold or crease. However, their upper eyelid fold is typically an outfold. This is because these types of Caucasians do not have an epicanthal fold (Mongolian fold). The other type is a very high upper eyelid fold or crease. This fold or crease starts high immediately below the brow skin. There is essentially no hooding of the upper eyelid skin. And there is minimal orbital fat underneath the eyelid skin. Thus, among Caucasians, there is upper eyelid crease that looks similar to that of Asian double eyelid fold (but slightly larger than that of Asians) and there is upper eyelid fold or crease that is significantly larger and different than that of an Asian double eyelid fold or crease. In the next blog, we will discuss why there is two very different types of upper eyelid fold or upper eyelid crease among Caucasians.
