Jrnl. 25 Aug. 194/2 In the few cases of purulent ophthalmia that have been treated with protargol the length of the course of the disease has apparently only been slightly shortened, but the severity of the attack has been decidedly lessened. 1907J. H. Parsons Dis. Eye xxix. 580 In more severe cases..protargol, 15 to 20 per cent., should be rubbed into the margins of the lids with a stumpy camel's hair brush. 1938Stain Technol.
