The eyeground is yellowish-gray or khaki color, uniformly covered 

 with a dense mass of minute white dots, that are smaller and denser 

 at the macular region. A few dull-red choroidal capillaries are 

 visible on the lower part of the fundus near the periphery. The 

 optic nerve head, dull white, long and narrow, has a rounded upper 

 end. Its entire central area appears as if it were a mass of fine, 

 brown pigment dots. The pecten is exceptionally long, rather nar- 

 row, spirally arranged and extends beyond the range of vision 

 through the undilated pupil. 



To the nasal side and a little above the end of the disc is the 

 macular region, a dull-brown crater-like depression bounded by a 

 white mass of (reflex) st nations. Opaque nerve fibres radiate from 

 both sides of the disc but finally disappear as they approach the 

 boundaries of the fundus.

The general color of the eyeground is a slate-gray, with a pale- 

 yellow tint in the lower half of the eyeground. The entire Held is 

 besprinkled with irregularly shaped, light-gray dots, giving it the 

 appearance of a rough and rather coarse surface, especially near the 

 macular area where the dots are more closely packed in I he shape 

 of a bright, circular patch. 



The optic nerve-head is quite white and of oblong shape. Several 

 orange-colored, choroidal capillaries are visible in this region, that is 

 covered with minute, brown, pigment dots, like black pepper grains. 

 Extending from each side of the optic disc is a large number of 

 opaque nerve fibres that extend across the fundal field. 



The pecten, of the usual chocolate-brown color, is rather irregular 

 in shape at its superior extremity. From above downward it looks 

 like a ship's tarred cable, becoming larger as it approaches its union 

 with the papilla. The superior end appears to come well into the 

 vitreous cavity and to reach the lens.
