PREVENTION, SYMPTOMS AND TREATMENT :I 



In the baldness following scaling of the skin, thorough and 

 frequent grooming is most useful with local inunction of sulphur 

 ointment dally. After some time, oil of cade may be added in the 

 proportion of one dram to the ounce of sulphur ointment. 



In alopecia areata there are circumscribed round spots of 

 baldness which resemble those of ringworm but there are no broken 

 hairs, scales, crusts or fungus. It is common in dogs and horses. 

 Treatment is conducted with the daily use of an ointment of ex- 

 tract of pilocarpus, 3 i ; sulphur ointment to make § i ; or the chry- 

 sarobin ointment, noted above, may be employed as frequently as 

 may be without producing too much skin irritation. Friedberger 

 advises one of the following: Creolin in alcohol (i-io to 20) ; tinc- 

 ture of iodine and alcohol, equal parts; or peruvian balsam and 

 alcohol (1-10). 



Amaurosis. 



Amaurosis is that form of total blindness occurring without 

 any apparent ocular lesion visible to the naked eye. There may be 

 a lesion discoverable, however, by ophthalmoscopic examination of 

 the fundus. Amblyopia is often used synonymously with amaurosis 

 but strictly refers to weakened or impaired vision (and not total 

 blindness) due to functional disease of the visual apparatus. 



The etiology of amaurosis (including amblyopia) embraces 

 the following conditions : Disease of the choroid, retina, optic nerve 

 or brain. Many general disorders produce disturbance of these 

 parts and amaurosis, as apoplexy, parturient apoplexy, renal dis- 

 ease, diabetes mellitus, lead poisoning, convulsions, cerebral tumor 

 and concussion, and hydatids. 



Amaurosis may be caused by blindness in the other eye (sym- 

 pathetic form). Functional disturbances of the visual apparatus, 

 which are more apt to result in amblyopia, are induced by debility, 

 severe anemia and hemorrhage, gastric disorder, impacted rumen, 

 pregnancy and lactation, large doses of quinine, exposure to the 

 glare of the sun and excessive copulation.
