The‘pupils are large, but their reactions are normal. ‘There is paresis of the left external rectus muscle, and lateral nystagmus develops when the eyes are directed to the left, that 1s to say, in levoversion. The ophthalmoscope reveals the following con- ditions: In the right eye papillitis, the apex of the swelling being 3 D. It is vascular in the extreme, but the centre of the disc is not markedly filled in. The veins are full and carry very dark-colored blood. There is no macular figure. In the left eye the papillitis is greater than on the opposite side, the apex of the swelling being 5 D. with decided engorgement, and the appearance to which the name choked disc is ordinarily given. The veins are even fuller and darker than upon the other side. The peripheral visual field for form of each eye is normal. There are no scoto- mas. Comment.—The double optic neuritis (choked disc), together with paresis of the left external rectus muscle and lateral nystagmus, especially when the eyes are directed towards the left, are ocular signs frequently seen in cerebellar dis- eases.
