Abstract :

AIM: To study the usefulness of B–scan ultrasonography in the evaluation of papilledema. METHODS: Sixty patients who were referred from the neurology and medicine department and patients who are clinically suspected to have papilledema were selected. Thorough, clinical examination with slit–lamp biomicroscopy and visual acuity assessment was done. These patients underwent B–scan ultrasonography to demonstrate the crescent sign and optic nerve sheath diameter(ONSD) . The patients were further evaluated with the neurologist and magnetic resonance imaging (MRI) thus confirming the diagnosis of papilledema. The results of our ultrasonographic evaluation were correlated with final diagnosis after thorough clinical evaluation, imaging and the neurologist’s opinion. RESULTS: Out of 60 patients diagnosed having papilledema on MRI, 54 (90%) showed crescent sign and 55(92%)mean optic nerve sheath diameter(ONSD) of 4.85( ±0.66)on B scan ultrasonography. Headache was the most common presenting complaint in 52 (86%) and idiopathic intracranial hypertension was the most common underlying cause of papilledema in 40 (67%) cases. CONCLUSION: “Crescent sign” and Optic nerve sheath diameter(ONSD) seen on ultrasonography are a sensitive tool for the diagnosis of papilledema. It is a cost–effective, less cumbersome and effective tool to differentiate between papilledema and pseudo papilledema before subjecting the patients to costly investigations like MRI. A positive crescent sign with optic nerve sheath diameter more than 3.3mm should always be followed by MRI to find out the cause of papilledema
