Atrophy of Nerves. 189 



certainty from the complete muscular paralysis, wasting and 

 degeneration of the muscles supplied by the nerve, and by the his- 

 tory of the case (haemoglobinuria in atrophy of the triceps exten- 

 sor cruriSj roaring in atrophy of the laryngeal muscles and recur- 

 rent nerve). In other cases, as in the eye, we have the atrophy 

 of the eyeball, the distortion or complete paralj^sis of the iris, the 

 ■opacity of the lens, or the exudation into the vitreous, choroid and 

 retina when these can still be observed. 



Prognosis will depend on the cause. With a nerve severed with 

 a knife or crushed in a part of its course and atrophied, without 

 destructive changes in the organs in which it is distributed, repair 

 is possible and to he expected in time. 



Treatment is expectant, yet inflammation must be subdued, 

 tumors removed, divided ends ligatured, etc.
