Orbital inflammatory disease and secondary optic neuropathy is a rare but devastating complication of long-term intranasal cocaine abuse. We describe 2 patients with a history of intranasal cocaine consumption who presented with subacute onset of unilateral vision loss from optic neuropathy and limitation of abduction in the affected eye. Magnetic resonance imaging findings included an orbital mass in combination with absent nasal septum and partial destruction of the paranasal sinuses. Biopsies and histopathologic examination of the nasal cavity and the orbital mass revealed chronic inflammation. Both patients were treated with oral corticosteroids, ocular movements completely normalized but no improvement of visual acuity was noted. Intranasal cocaine abuse can cause orbital complications from chronic sinonasal inflammatory disease and these patients are at risk to develop optic neuropathy. Optic neuropathy may be caused by compression, infiltration, or ischaemia.
