with hypopyon by this method. This operation was, however, 
not made use of until Guthrie in 1884 (improved later by Sae- 
misch) advocated the treatment, and since then different 
modifications of the original method have been used with more 
or less success. Thus I can give you an interminable list of 
prominent ophthalmologists of different nationalities giving tes- 
timony to the subject. 
This report is based upon twenty-two cases admitted and 
treated in the department of ophthalmology, otology and rhino- 
laryngology in the Philippine General Hospital. 
Age.—tThe age varies from 4 to 81 years. The majority of 
the cases however were 45 years of age. 
Sex.—Almost twice as many males were affected as females, 
the relation being 14 males to 8 females. This greater per- 
centage of males is explained by the fact that they are more ex- 
posed than are females. 
Etiology.—tin this series of twenty-two cases, the majority 
of cases of corneal infection were caused by traumatism through 
injuries of various kinds inflicted upon the corneal surface, 
which subsequently became infected, leading to most serious 
complications with disintegration of the corneal substance, 
panophthalmitis, and total loss of the eye. Such were the con- 
ditions of the patients admitted to the hospital; they were alto- 
gether too late for any satisfactory treatment. 
The following table shows the etiological factors producing the 
eye lesions of the twenty-two cases we now have on hand: 
A. Corneal injury due to: : Cases. 
Dust entering conjunctival sacs 
Tail of fish 
Sticks 
Grass leaves 
Leaf of rattan 
Leaf of rice 
Leaf of bamboo 
Buri strip (dried leaf) 
Tin can 
Coconut shell 
A piece of bone 
B. Causes not well known by the patients 
As a rule these patients received the injuries to the eyes acci- 
dentally and while performing their daily duties of life. Those 
working on farms are more subjected to corneal injuries pro- 
duced by leaves of grass, rice, and other plants, as shown by 
the three cases.
