    cells of the retina disappear over the conus and the layer, of rods and cones is not seen over this area. With the increase of the myopia the atrophy extends to the nasal side of the optic disc and forms a complete ring around it. In advanced cases the changes about the yellow spot speak for an inflammatory condition. Numerous whitish lines and spots of exudate, together with small hemorrhages, are sometimes seen. Sehnabel contends that the appearances of the conus in high degrees of myopia are not due to inflammatory changes, but that they are congenital defects. Accord- ing to this author, the bacillary and pigment layers were never formed over the area of the conus, and so could not be drawn away. I have several times observed cases of localized chor- oiditis with descemetitis similar to the anomalous forms described by Hill Griffith. In these there was dimness of vision coming on suddenly. Examination showed distinct spots on the posterior surface of the cornea, but there were no signs of iritis or irido-cyclitis. In other cases, however, there were iritic complications and also dust-like opacities in the vitreous, so that I am in- clined to believe that in most cases where descemetitis is present there is some involvement of the anterior part of the uveal tract. In both choroido-retinitis and cen- tral choroiditis I have observed that opacities of the vitreous, so faint as to escape a hurried examination without mydriatic, precede the manifest choroidal lesion, even in cases that are clearly nonsyphilitic.
