The eyeground is a very pale uniform gray stippled with darkergray and white dots, thus giving the whole field a granular appear-ance. The horizontally oval macular area (on the nasal aspectnear the upper end of the disc) assumes a pinkish tone. At its centreis a small pit with a brilliant, white central dot. Around the macularregion is a pale, blue-gray reflex which loses itself in the general toneof the fundus, but appears quite sharp on the inner side of the ovalmacular region. The disc is a narrow, white oval, whose length isabout one-third the height of the pecten. A number of opaquenerve fibres run across the background at right angles to the papillaand fade into the general gray of the fundus. The pecten arisesfrom the upper part of the disc, spreads out on it like the root of atree and gradually disappears into the papillary substance. Fromthis root a long, slender, spiral f
