Swollen Optic Disc and Sinusitis

PURPOSE To present a case of optic disc swelling caused by sinusitis. METHODS Ocular symptoms were investigated using computed tomography imaging of the facial bones to detect the relationship between the sinus inflammation and the optic nerve. RESULTS A particular configuration of the optic nerve was detected. Optic nerve course through the inflamed sphenoidal sinus is a condition associated with a greater risk of inflammation. CONCLUSION Sinusitis is a rare but treatable cause of optic neuritis. The choice of the correct radiological investigation to be done to set up a proper treatment of the sinus pathological condition is also essential for the resolution of ocular symptoms.
