Orbital penetrating injuries from pencils are rare. This report describes a case of penetrating orbital injury in a young child with a retained blue-colored pencil core foreign body, which led to rapid onset of orbital abscess requiring surgical drainage. Intraoperatively, orbital tissues were stained a bright-blue color. Histopathological study of specimen also highlighted bright blue aggregates of foreign material infiltrating the orbital tissues. Cultures grew Streptococcus mitis and Exophiala jeanselmei , which are rare causes of orbital abscess. Unique properties of retained colored pencil core as compared to graphite pencil core are herein discussed. Due to differences in composition, colored pencil core foreign bodies may require more timely surgical intervention compared to noncolored graphite pencil core.
