Diseases of the Eyes and their Appendages. 225 



of the eyelids press upon the eyeballs and occasion much 

 irritation and inflammation by movement. 



Treatment is by a surgical operation, in which a portion 

 is removed from the upper part of the eyelid. Extreme 

 care is afterward needed to prevent the animal doing 

 injury by rubbing the affected parts. 



Laceration of the Eyelids calls for immediate and 

 careful attention, or complete union is impossible. Recent 

 wounds may be closed by any of the usual sutures, fol- 

 lowed by appropriate dressings. Fatal terminations are 

 not uncommon, from the setting in of erysipelatous 

 inflammation. 



Warts occasionally are present on the eyelids or upon 

 the eyebrows, and, when pedunculated, are easily re- 

 moved by ligature ; but, when diffused, present no little 

 difficulty. They appear to be asso- 

 ciated with some peculiarity of consti- 

 tution, and disappear when changes 

 in the system take place. 



Fungus H/ematodes, Blood Fun- 

 gus, consists of a dark-coloured, irre- 

 gular, and repulsive-looking tumour, 

 protruding from the orbit, growing 

 with remarkable rapidity, and displac- 

 ing the eyeball entirely. The surround- 

 ing bones are sometimes involved, and 

 death eventually arises from blood- 

 poisoning or hectic. 



Treatment consists of complete ex- 

 tirpation, which is a formidable operation, and not always 

 successful. Fortunately for the horse, in him the disease 

 is rare.
