Choroidal vesselsare numerous and run in rather straight, vertical lines on both sidesof the optic disc. They are dull orange in color. The fovea isshown towards the anterior or nasal half of the retina, and appearsas a round hole or crater-like depression, brown in color, which re-flects a grayish sheen from its centre. A narrow gray circle or reflexring surrounds this pit. The optic disc has its central portion apparently stippled withbright orange-red dots, while its margin is fringed with coarse, whitefibres, that are also studded with brown pigment dots, especially nearthe outer border. The pecten is of the usual, deep chocolate-brown color, rathernarrow where it joins the disc but becoming much thicker and moremassive as it projects into the vitreous towards the lens. CARINATvE.
