306 DISEASES OP THE EYE. 



nea is injured, as may occur from a sharp instrument penetrat- 

 ing the eye, and the aqueous humor is evacuated, the lens is 

 liable to fall out, in which event of course the usefulness of the 

 eye is lost. In the treatment of all wounds of the eye try to 

 keep down the inflammation and endeavor to maintain an 

 aseptic condition. Always use weak solutions to drop into the 

 eye, and in many cases the addition of one drachm of a four per 

 cent, solution of cocaine added to one ounce of the lotion Avill 

 give excellent results by relieving the pain. In all cases of in- 

 flammation in and around the eye, it is a good plan to use atro- 

 pine directly to the organ. This by dilating the pupil prevents 

 the organization of the inflammatory exudates, or, better still, 

 use the atropine solution in the following manner : 



Sulphate of atropia 2 grains 



Cocaine hydrochlorate sol. 4 per 



cent 1 drachm 



Distilled water 1 ounce 



Use for two or three days, applying a few drops to the eye several 

 times a day. And then 



Take. Eserine 2 grains 



Distilled water 1 ounce 



and use this for two or three days. 



The atropia solution dilates the pupil while the eserine solu- 

 tion has the opposite effect. In this manner the pupil is kept 

 moving, lessening the possibility of organization of the products 

 of inflammation. An opaque cornea, when of recent occurrence, 

 can often be corrected by stimulation. To effect this apply with 

 a feather or camel's hair brush a solution of the nitrate of silver, 

 such as 



Nitrate of silver x grains 



Distilled water 1 ounce 



Apply this directly to the opacity once or twice a day. It is a 

 good plan to administer internally saline diuretics, such as nitrate 

 of potash in-drachm doses, and a full dose of Epsom salts.
