1 3 o THOMPSON YATES LABORATORIES REPORT 
conjunctivae were red and oedematous, large subconjunctival ecchymoses having 
taken place between the sclerotic and the ocular conjunctiva ; the cornea was bright 
and remained unaffected throughout. The acute symptoms quickly subsided without 
treatment, recovery taking place in four to five days. 
Films of the discharge were made, streptococci in chains being the only 
organism observed. 
VI. Ophthalmia caused by Staphylococci 
Two cases of inflammation of the eye have been examined in which 
microscopically and culturally only the staphylococci could be observed. 
Sydney Stephenson 41 records a case of acute ophthalmia, associated with 
pustular eruptions on the face and scalp, in which staphylococcus aureus and albus 
alone occurred. In my cases staphylococcus aureus and albus were found associated 
together. No other organism occurred to which the inflammatory condition could be 
ascribed. 
The inoculation experiments with the organisms obtained from healthy eyes 
demonstrate that the staphylococci are able to cause an acute inflammation, and it is 
not improbable that in certain conditions of lowered general or local vitality the 
staphylococci which happen to be present in the conjunctival sac during such conditions 
are capable of originating an acute inflammation. 
It is undoubted that in some chronic inflammatory conditions the continued 
inflammation is chiefly due to the presence of the organisms of suppuration. 
VII. Acute Ophthalmia in a dog caused by Staphylococcus Albus 
The dog had had an attack of inflammation some weeks previously which had 
incompletely resolved. 
This first attack followed directly on the formation of a discharging sore on 
the upper eyelid through the biting of flies ; the inflammation was not intense, and 
subsided in about three weeks, leaving the conjunctival mucous membrane slightly 
hypertrophied. After a month had elapsed the eye again became acutely inflamed. 
The eyelids were puffy and gummed together, enclosing a large amount of yellow 
pus. The conjunctiva was very red, swollen, and rough. One eye alone was affected 
at first. 
In a short time after the onset of the inflammation the cornea was noticed to 
be becoming hazy ; the haziness was general and increased rapidly in density, until 
the whole cornea was densely opaque and pearly- white. The inflammation soon 
extended to the other eye, which exhibited the same symptoms in a modified degree.
