Penetrating colored pencil injury with Clostridium bifermentans pre-septal cellulitis: case report, literature review, and treatment algorithm.

Abstract

The incidence of penetrating orbital injuries from writing instruments continues to rise in the pediatric population. Such injuries can cause significant visual morbidity and have a lifelong psychosocial impact. While the description of graphite pencil-related orbital trauma management is well demonstrated with over 40 reported cases, a lack of consistent management protocol for colored pencil-related injuries. Here, we report an inadvertent penetrating orbital colored pencil injury with progressive mechanical ptosis and pre-septal cellulitis necessitating urgent orbitotomy, debridement, and washout to reduce inflammatory and infectious burden. The wooden body serves as a nidus for polymicrobial infection, and the unique composition of colored pencil cores may lead to inflammatory processes that require vigilant multidisciplinary surgical and medical management reflected in our literature review.
