A recent study found that increased optic canal area on magnetic resonance imaging was associated with worse papilloedema in idiopathic intracranial hypertension (IIH). We repeated this study using more accurate computerized tomography derived measurements. Optic canal dimensions were measured from 42 IIH patients and 24 controls. These were compared with papilloedema grade. There was no correlation between any of the optic canal measurements and papilloedema grade and no significant difference in optic canal measurements between patients and controls. Our results cast doubt on the existing literature regarding the association between optic canal size and the degree of papilloedema in IIH. CT delineates bony anatomy more accurately than MRI and our CT-derived optic canal measurements cast doubt on the existing literature regarding the association between optic canal size and the degree of Papilloedema in IIH.
最近一项研究发现，在特发性颅内高压（IIH）患者中，磁共振成像显示的视神经管面积增加与更严重的视乳头水肿相关。我们使用更精确的计算机断层扫描测量方法重复了这项研究。从42例IIH患者和24例对照者中测量视神经管尺寸，并将其与视乳头水肿分级进行比较。视神经管的任何测量值与视乳头水肿分级之间均无相关性，患者与对照者的视神经管测量值也无显著差异。我们的结果对现有关于IIH患者视神经管大小与视乳头水肿程度之间关联的文献提出了质疑。计算机断层扫描（CT）比磁共振成像（MRI）更能准确描绘骨骼解剖结构，我们通过CT得出的视神经管测量结果对现有关于IIH患者视神经管大小与视乳头水肿程度之间关联的文献提出了质疑。
