在会议开始时，明尼苏达大学医学博士 Michael S Lee 介绍了一项回顾性研究，评估视交叉前视神经 (PCON) 和眶中视神经 (MOON) 之间的磁共振成像 (MRI) 信号强度差异。对 75 名无视神经病史的患者进行对比前和对比后轴向 T1 加权脑 MRI 信号强度测量。他们的研究显示，与正常视神经中的 MOON 相比，PCON 的平均强度比更高，并得出结论，在使用 MRI 帮助诊断疑似视神经炎患者时，认识到这种生理信号差异非常重要。 Henry Ford Health 医学博士 Odei Alayyas 介绍了一名 28 岁男性的病例，该男子出现慢性头痛急性恶化、进行性周边视觉障碍和步态不稳定。他被发现患有弥漫性反射亢进、双颞侧偏盲，并有视网膜神经纤维层（RNFL）变薄和神经节细胞层（GCL）损失的证据，呈双鼻模式，垂直中线。脑 MRI 显示视神经内均匀增强病变
To begin the meeting Michael S Lee, MD, University of Minnesota, presented a retrospective study evaluating the magnetic resonance imaging (MRI) signal intensity difference between the prechiasmatic optic nerve (PCON) and mid-orbital optic nerve (MOON). Signal intensity was measured on pre-and post-contrast axial T1-weighted brain MRI of 75 patients without a history of optic neuropathy. Their study revealed brighter intensity ratios of the PCON on average as compared with the MOON among normal optic nerves and concluded that recognition of this physiological signal discrepancy is important to account for when using MRI to help in the diagnosis of patients with presumed optic neuritis.Odei Alayyas, MD, Henry Ford Health, presented a case of a 28-year-old man who presented with acute worsening of chronic headaches, progressive peripheral visual disturbances, and unsteady gait. He was found to have diffuse hyperreflexia, bitemporal hemianopia with evidence of retinal nerve fibre layer (RNFL) thinning and ganglion cell layer (GCL) loss in a bi-nasal pattern respecting the vertical midline. Brain MRI showed homogenously enhancing lesions within the optic
