PREVENTION, SYMPTOMS AND TREATMENT vg 



confuse conjunctivitis with inflammation of the cornea, or deeper 

 parts of the eye, as inflammation of the iris or ciliary body (cyc- 

 litis) or glaucoma. In these conditions the congestion is chiefly 

 in the sclera about the cornea, and not general; lachrimation is 

 more prominent than a mucous or purulent discharge ; photophobia 

 is marked; the pupil often fails to react readily to light; the color 

 of the pericorneal congested area is pink rather than the general 

 brick-red injection of superficial vessels seen in conjunctivitis. In 

 these more serious affections the superficial vessels of the ocular 

 conjunctivae are not especially enlarged and sight is apt to be im- 

 paired. In conjunctivitis both eyes are usually attacked, though 

 often one is affected before the other. The absence of foreign 

 bodies in the eye must be determined. 



The treatment of acute catarrh of the conjunctiva consists in 

 the use of the following prescription : 



Zinci Sulphatis gr. ss 



Acidi Borici gr. xii 



Aquae Dest Si 



M. 



Sig. Drop in the eye thrice daily. 



At night it is well to rub on the lids boric acid ointment. The 

 disease is likely to be self-limited to a period of 10 days, or longer, 

 but may become chronic. 



Pink Eye is an epizootic, contagious form of acute conjunctivi- 

 tis and in human practice has been shown to be caused by the Week's 

 bacillus or pneumococcus more commonly. The chronic form of 

 conjunctivitis may be due to bad hygiene, dust, irritant gases, 

 rhinitis, ectropion, etc. The treatment consists in removal of the 

 cause and the use of the zinc and boric acid solution. 



Purulent conjunctivitis is almost always due to gonnococcus 

 infection in man, but while this may occur in animals from con- 

 tact with the human patient, yet in animals is also due to other
