The problem
Unwanted visibility of blood vessels through upper or lower eyelid skin is present. These vessels, usually veins, appear as blue or purple discoloration in a line or cord. They may have some degree of bulging.
Causes
Normal veins reside under the skin throughout the body. They may be more visible in areas with thin skin, such as the upper or lower eyelids. Skin of light color will transmit outlines and colors of underlying structures more readily.
Veins may become more prominent or enlarged in states of inflammation, infection, or in situations that impede blood outflow.
Often seen with
Thin skin and light skin color.
Not to be confused with
Excess skin pigment, eyelid shadowing, lower eyelid hollowing.
