 DISEASES OF THE EYE. 



OPHTHALMIA— INFLAMMATION OF THE EYE. 



The disease yields readily to treatment in the mild form. 

 When it occurs as an epizootic in kennels it proves more stub- 

 born. 



Symptoms. — There is a redness of the conjunctiva, tenderness 

 to light, and a secretion of tears. The eyeball is retracted in the 

 socket. There is an extravasation of blood within the conjunc- 

 tiva, which may increase as the disease advances. The cornea 

 becomes opaque. If the disease is not arrested, ulceration may 

 take place and the sight be destroyed by the bursting and dis- 

 charge of its contents. 



Causes. — It is caused in various ways, as by injuries to the 

 eye, bad feeding, lodging, want of exercise, extremes of heat and 

 cold, etc. 



Treatment. — Give two drachms of epsom salts. The eye 

 should be fomented several times a day with cold water in the 

 summer and wann water in the winter. After the eye has been 

 thoroughly fomented, a lotion composed of zinc sulphate, grains 

 five; water, ounce one; laudanum, drachm one; belladonna tinc- 

 ture, drachm one, should be put into the eye with a sponge. 

 Weak vinegar and water, with a small portion of laudanum, is 

 said to be good. 



CHRONIC OPHTHALMIA. 



In this form the discharge from the eyes is not so great. The 

 conjunctiva is not so red or congested. The inner side of the lid 

 is ulcerated.
