Periorbital hyperpigmentation is defined as bilateral, homogeneous hyperchromic macules and patches primarily involving the lower eyelids but also sometimes extending towards the upper eyelids, eyebrows, malar regions, temporal regions and lateral nasal root. The age of onset is usually after puberty or in early adulthood (16-25 years). It is more pronounced in certain ethnic groups and is also frequently seen in multiple members of the same family."
