Orbital hematoma due to vitamin K deficiency in an infant.

We report a rare case of late-onset vitamin K deficiency bleeding in a 3-month-old boy who presented with orbital compartment syndrome due to massive bleed in the right orbit. The coagulation profile was highly abnormal. The patient was treated with vitamin K injections, following which the coagulation profile normalized. The orbital hematoma required drainage because of severe proptosis with orbital compartment syndrome. The patient subsequently developed a corneal opacity, but there was no recurrence of bleeding.
