PREVENTION, SYMPTOMS AND TREATMENT I4 - 



Treatment. —Confine the animal in darkened quarters. Give a 

 brisk purge. Apply hot fomentations for half hour's duration three 

 times daily to affected eye. Two or three leeches placed on the 

 temple will produce local abstraction of blood and relieve the con- 

 gestion. A one per cent, atropine solution should be dropped into 

 the eye four to six times daily in the case of the large animals ; one 

 drop only of this strength should be used in the small animals, and 

 at less frequent intervals to avoid poisoning. Atropine prevents ad- 

 hesions of the pupil to the lens. 



Internally, full doses of sodium salicylate with potassium 

 iodide are of benefit (of each, H., §ss; D., gr. v-x, thrice daily). 

 With increased tension of the eyeball and threatened glaucoma, 

 pilocarpine may be given internally (H., gr. ii-iii; D., gr. */&, 

 thrice daily). 



Sympathetic iritis in its early stage calls for enucleation of the 

 other eye — providing the other eye is useless for vision. 



Iridectomy may be indicated following an attack of iritis to 

 remedy an occluded pupil or adhesions of the iris to lens capsule 

 (posterior synechiae). 



Jaundice (Catarrhal). Gastro-Duodenal Catarrh. Cholangitis. 



This form of jaundice occurs most commonly in dogs and 

 horses and must be distinguished from jaundice due to serious or- 

 ganic diseases of the liver. It is due generally to gastro-duodenitis, 

 so that it is preceded in most cases in dogs by vomiting. It may 

 arise in horses as a complication of influenza and other infections. 

 Icteric ocular conjunctivas, and mucous membranes, light-colored 

 feces and dark-colored urine (showing yellow foam on shaking) 

 are characteristic of this and other forms of jaundice. 



Recovery in a few weeks is the rule in horses; in dogs a fatal 

 result is not uncommon. 



Jaundice is produced by obstruction of the common bile duct 

 near its outlet in the duodenum through catarrh of the duct, causing
