136 OPHTHALMOLOGY FOR VETERINARIANS 



It is of the utmost importance, in passing one's judg- 

 ment upon the soundness of an animal, that the optic 

 nerves be examined — in fact, the whole fundus of the 

 eye; for, however sound an animal may be otherwise, 

 if the fundus is or has been diseased, it materially 

 lessens the animal's value. In order to determine a 

 pathologic condition one must become famihar with the 

 normal fundus, and advantage should be taken of every 

 opportunity to learn its details.
