Woinids of the Conjunctiva. 359 



The clean tip of the finger passed under the lid and nictitating 

 membrane is a safe and effective method. Less effective methods 

 are to pick up the offending body on the point of a lead pencil, or 

 a small, blunt metallic spud, or with a pin's head covered with a 

 clean pocket handkerchief. This may be followed by an anti- 

 septic (boric acid) collyria, with or without cocaine or morphia. 



WOUNDS OF THE CONJUNCTIVA. 



These occur in all domestic animals, but are especiallj* fre- 

 quent in dogs and cats from scratching with the claws. In 

 clumsy handling of the eyelids, the mucosa is wounded by ragged 

 and uneven nails. Injuries and .stings b}' insects which are at- 

 tracted by the reflection from the eye constitute a specially grave 

 lesion, often proportionate to the nature of the poison in.stilled. 



Symptoms. There are usually closure of the eyelids, with 

 exudation and thickening of the conjunctiva especially in the 

 vicinity of the wound, a free flow of tears, mingled it may be 

 with blood, and the visible evidence of the lesion on the exposure 

 of the injured part. If the cornea is implicated, even the pupil 

 is contracted, showing photophobia. 



Treatment. Slight noninfected wounds will heal readil}- under 

 simple astringent collyria, following upon the removal of any 

 cause of mechanical irritation. A .solution of corrosive sublimate, 

 I : 5000, or of boric acid, 4 per cent, maj' be used. If photopho- 

 bia exists '2 per cent, of atro{)ia sulphate or i per cent, of cocaine 

 113-drochlorate will usuall}- give relief. Extensive wounds may 

 require sutures, and sloughing tissue ma}' be excised with fine 

 curved .scissors. Excessive granulations may be removed in the 

 same way. For .stings use a potassium permanganate solution 

 (2 grs. to I oz). Violent inflammation may be met b}' a laxative 

 and by leeching the periorbital region.
