许多患有多发性硬化症的病人在眼科检查时，在他们的一些视网膜静脉上出现了一种特殊的白色鞘。在某些情况下，它表现为静脉壁增厚，特别是在其周围分支。在其他情况下，它以小的白色斑块的形式覆盖在静脉上，偶尔也可能出现管腔口径狭窄。在正常的视网膜中，血管壁是透明的，因此看不见。检查者只能看到他们体内的血柱。在视神经的头部，多余的支撑组织有时会在血管周围形成白色的袖口。当这些袖口局限于视盘时，它们仅仅是发育异常。当它们超出椎间盘边缘时，表明先前存在炎症反应或乳头水肿，
A number of patients afflicted with multiple sclerosis present on ophthalmoscopic examination a peculiar white sheathing of some of their retinal veins. In certain instances it appears as a thickening of the walls of the veins, especially in their peripheral branches. In other instances it takes the form of small white plaques overlying the veins, and there occasionally may be a constriction in caliber of the lumen. 1 In the normal retina the walls of the blood vessels are transparent and therefore invisible. Only the column of blood within them is seen by the examiner. On the head of the optic nerve an excess of supporting tissue may at times form white cuffs around the vessels. Whenthese cuffs are limited to the optic disk they are merely developmental anomalies. When they extend beyond the margins of the disk they indicate the previous presence of an inflammatory reaction or papilledema,
