82 OPHTHALMOLOGY FOR VETERINARIANS 



place the index-finger of the other hand, or a probe, 

 about midway between the margin and the upper por- 

 tion of the Hd, as a fulcrum, and lift the lid upward. 

 This will evert the lid and it can easily be inspected. 

 If a foreign body be seen, wet with an antiseptic solu- 

 tion a small piece of cotton, and, after squeezing out 

 the excess of fluid, wipe away the body. Sometimes the 

 foreign body may become lodged in the retro tarsal fold; 

 in such cases make a small swab by twisting a piece 

 of cotton on the end of a probe, wet this and sweep 

 it under this portion of the hd, when it will be dislodged. 

 The foreign body may be hidden in the folds about the 

 inner canthus and nictitans membrane, when only the 

 most careful search will reveal it. 



When a foreign body is on or embedded in the cornea 

 it requires the most careful treatment. First, try a 

 small piece of cotton, well twisted and free from loose 

 fibers, and quickly wipe over the body, when, m many 

 cases, it will become caught in the cotton and removed. 

 It if cannot be readily removed by this method, use a 5 

 per cent, solution of cocain, and with a small knife- 

 needle gently prick about the body and remove it, 

 doing as Httle damage to the corneal epithelium as pos- 

 sible. If the epithelium is much roughened by this 

 operation, smooth it gently with an eye spatula or the 

 smooth, rounded portion of a shell spoon. Of course, 

 strict antisepsis must be observed in all cases. The
