Multimodal Imaging of Optic Nerve Drusen in a 10-year Hyperopic Child.

Optic nerve drusen (OND) are abnormal calcified acellular deposits located within the prelaminar portion of the optic nerve. They are usually asymptomatic and detected incidentally during fundoscopic examination. They have a clinical significance due to their appearance which mimicks true papilledema, if the drusen are buried. Misdiagnosis of an OND as papilledema may cause unnecessary and invasive interventions, like lumbar puncture for elevated intracranial pressure.  We present a case of buried OND in a 10-year hyperopic girl who was referred to our clinic with the complaint of headache and swollen optic discs bilaterally. After diagnostic tests, including B-scan ultrasonography (USG) and enhanced depth imaging optic coherence tomography (EDI OCT), she was diagnosed with bilateral OND.
