284 BACTEBIOLOGY OF THE EYE 



It should be noted that the not uncommon form of dacryocystitis in 

 the newly-born, due to delay in the opening of the nasal duct, is 

 generally quite free from bacteria, and is caused by a collection of 

 detritus and mucus in the sac (Michel, Vossius, Cirincione, Terson, 

 Wintersteiner, Topolanski, Rabinowitsch). A secondary infection 

 soon occurs, the secretion becomes more and more purulent, and, as I 

 have often been able to demonstrate, shows no material difference 

 from the dacryocystitis of adults. In many cases I have found 

 Pneumococci and Staphylococci. Hirch found Pneumococci. Valude 

 found the Tctragenus. Antonelli found (presumably) Gonococci in the 

 intact conjunctiva (his findings in the absence of cultures are not 

 proof of the presence of the Gonococcus). Selenkowski cultivated very 

 virulent Staphylococcus aureus. Such cases of dacryocystitis or dacryo- 

 stenosis congenita can simulate a primary purulent conjunctivitis. 

 Peters is right, therefore, in stating that attention should be paid 

 to the duct in all cases of non-gonorrhoeal suppuration in the newly- 

 born. Pe"chin named this condition a 'pseudo-conjunctivitis' a 

 name against which Fejer protested, as it has nothing to do with the 

 conjunctiva. Care must be exercised in the examination of these 

 cases, as sometimes it is only after deep pressure in the fossa lacri- 

 malis with a glass rod that the pus will be evacuated from the sac. 

 It would be going too far were we to consider all cases of non-gonor- 

 rhceal catarrh as invariably of this type. In all cases of gonorrhrea, 

 too, it is advisable to examine the lacrymal passages.
