Treatment of idiopathic cutaneous hyperchromia of the orbital region (ICHOR) with intense pulsed light.

Background: Idiopathic cutaneous hyperchromia of the orbital region (ICHOR) does not have a clear etiopathogenesis. Genetic factors, increased melanin, prominent vasculature, and eyelid skin slackness seem to be involved.

Objective: To evaluate individuals with ICHOR clinically and histologically, before and after treatment with high-energy pulsed light (HEPL), considering epidermal and dermal melanin, in order to evaluate HEPL efficacy in clearing away ICHOR, and 1 month and 1 year later to check whether improvement was maintained.
