Silent orbitocranial penetration by a pencil.

OBJECTIVE To emphasise the value of computed tomography even in the absence of symptoms in a case of penetrating injury of the upper eyelid. METHODS Case report. RESULTS Although clinically asymptomatic, penetration of upper eyelid was associated with intracranial penetration that left a track in the brain parenchyma. CONCLUSIONS Computed tomography of orbit and brain is an important investigation, even in seemingly trivial eyelid injury, to reveal the full extent of the damage.
