    longish spots of pigment. The margin is sharply defined by a seam of pig- ment, and within its limit there are a large number of fine, straight retinal vessels visible. The remaining portions of the fundus present, in general, a normal color and coarse granular appearance. Extending from the macula lutea nearly to the apex of the conus, there are a large number of spots, mostly round and of a light yellow color. They have a slightly convex sur- face and lie behind the retina and though not surrounded by pigment, still are sharply defined. Only the smaller ones are less sharply defined, they are of a more reddish color, lightly granulated and lie deeper. On one of the larger spots near the conus, there is a dark, sharply defined spot of pigment visible. The central vessels present the characteristic appearance as found in staphyloma posticum (see Fig. Ill—112.) Plate XVIII. Fig. 122. Choroiditis in an Eye Rendered Myopic by Staphyloma Posticum.40) The optic disk is of a uniform reddish color. The scleral ring is everywhere distinct, partly bordered by a seam of pigment, and only on the outer side it is not so distinctly defined. On the outer side it is in- closed by a conus, two thirds of the diameter of the disk in width, which is of a yellowish white color and covered with pigment spots. The deeper spots are of a faint reddish brown color, less distinctly outlined, and correspond to the interspaces of the choroidal vessels: the superficial ones are darker, more sharply defined and irregularly arranged. The margin of the conus is formed by a seam of pigment of irregular width. In the region of the macula lutea there is an irregular, longish yellowish white space, which is one and one half diameters of the disk in length and one in width, and separated by about one fourth a diameter from the outer border of the conus. It lies in the plane of the Choroid and is covered by numerous fine stripes and spots of pigment and sur- rounded by a seam of pigment. The seam is in places only a line, while in other places it spreads out to a width several times that of a larger vessel; it fades away towards the periphery.
