Treatment——Tapping through the sclerotica, followed 
by continuous pressure, secondary infiltration may occur, 
and tapping may be again resorted to. This treatment has 
been successfully adopted by the author on two occasions, 
the eye being punctured immediately behind the outer 
margin of the cornea. In one operation a drachm of clear 
watery fluid was removed; in the other, half-an-ounce of 
a deep amber-coloured fluid, approaching red. After each 
evacuation the eye assumed its natural size and position ; 
a cold wet sponge was placed’ over it, and maintained zz 
situ by a head cap. The sponge was re-applied daily for a 
week ; and then one drop of a weak solution of iodine was 
each morning placed on the eye-ball for the removal of 
the opacity, and the result proved satisfactory. In persistent 
cases the application of iodine round the eye, and atropine 
injections, are sometimes beneficial.
