Abstract

|
|
|
Optic neuritis (ON) is an acute or subacute inflammatory or demyelination process affecting the optic nerve. ON can be classified ophthalmologically as retrobulbar neuritis, papillitis, neuroretinitis. Retrobulbar neuritis, in which the optic discappearance is normal, is the most common cause of ON, but in many cases no apparent etiology is found. Paranasal sinusitis as a cause of ON is rare. Management of retrobulbar neuritis which is combined with paranasal sinasitis is controversial. Recently, we experienced a case of retrobulbar neuritis which was combined with paranasal sinusitis without orbital complication. It was treated by endoscopic sinus surgery and endoscopic optic nerve decompression in addition to intravenous antibiotics and corticosteroids. Visual acuity was improved nearly to a normal state after the treatment. The most possible pathophysiologic mechanism of retrobulbar neuritis may be the direct spread of infection of the sphenoid sinus to the optic nerve.
