DISEASES OF THE EYE AND ITS APPENDAGES. 363 



TUMORS or THE EYELJDS. 



Occasionally tumors form upon or within the substance of the eye- 

 lid. These may be of a fibroid nature, and arise from the follicles 

 of the hair as sebaceous tumors, or may be in the form of an abscess. 

 In debilitating diseases the lids sometimes become swollen and puffy, 

 a condition which might possibly be taken for the growth of a tumor. 

 This generally disappears with the improvement of the health of the 

 animal. Warts not uncommonly appear on or about the eyelids of 

 cattle. 



Treatment. — The removal of a tumor in the vicinity of so delicate 

 an organ as the eye should not be attempted by anyone not qualified 

 for the operation. 



LACERATION OF THE EYELID. 



This accident is not uncommon where cattle are fenced in by 

 barbed wire ; an animal may be caught under the eyelid by the horn 

 of another; it may occur in the stable by means of a projecting nail 

 or splinter of wood. 



Treatment. — The edges of the wound should be brought together 

 closely and correctly, by means of pins pushed through very nearly 

 the whole thickness of the lid, extending through each lip of the 

 torn part; then a waxed silk or linen thread must be wound over 

 each end of the pin, crossing the torn line in the form of the figure 

 8 (PI. XXVm, fig. 9) ; the pins should be placed about three-eighths 

 of an inch apart. The projecting ends of the pins should be cut 

 off close to the ligature, and the parts kept anointed with vaseline, 

 to which has been added 5 per cent of creolin. In place of a pin 

 suture, silver wire, catgut, or strong linen thread may be used in the 

 way of an ordinary suture. 



FOREIGN BODIES IN THE EYE. 



Splinters of wood, hedge thorns, pieces of cornstalk or leaves, stems 

 of hay or straw, twigs of trees, or weeds may penetrate into the eye, 

 break off and remain, causing inflammation, blindness, abscess, etc. 

 These substances may penetrate the eyeball, but more frequently 

 they glide off and enter between the eye and the ocular sheath. 



Treatment. — Their removal becomes often a very difficult task, 

 from the fact that the organ is so extremely sensitive, and the re- 

 tracting power so strong as to necessitate casting the animal, or even 

 the administration of sufficient chloroform to render it completely 

 insensible. The removal, however, is of paramount importance, 

 and the after treatment depends upon the extent and location of the 

 injury — cold water compress over the injured eye, the application of
