INDEX OP DISEASES AND REMEDIES 781 



OESTRUS EQUI. See BOTS. 



CESOPHAGEAL OBSTRUCTIONS. See CHOKING. 



Mechanical tumours ; Peri-cesophageal abscesses. 

 Pass probang or sound. 

 Remove obstruction if possible. 



(ESOPHAGEAL DILATATIONS. 



Difficult to treat. 



Feed frequently in small quantity on concentrated or semi-fluid food. 

 Partial excision of pouch and insertion of sutures successful in horse. 



CESOPHAGEAL PARALYSIS. 



Pass sound ; embrocations externally ; administer strychnine ; counter- 

 irritation. 



(ESOPHAGITIS. 



Inflammation of mucous membrane or muscle of gullet. 

 Give fluid soft food cold ; ice. 

 Refrigerant compresses. 

 .Antiseptic and mild astringent electuaries. 

 Stimulant embrocations to absorb hard circumscribed swellings. 



OPEN JOINT. 



Wound of joint with escape of synovia. 

 Healing by first intention promoted by fixing joint, cleansing wound, 



and antiseptic bandage or adhesive. 

 Inject wound with antiseptics, corrosive sublimate one part to 1000 of 



boiled water. 

 If wound suppurating or of several days' standing inject, two or three 



times a day, sterilised glycerin, or 3 per cent. sol. hydrogen 



peroxide. 

 Protect wound by frequently dusting with iodoform or chinosol ; or by 



applying several layers absorbent lint. 

 Severed surfaces may be sutured, provided movement of joint and 



tearing can be prevented. 



Splints and bandages secure support and protection. 

 Slinging horse prevents movements which might reopen wound, and 



removes weight which in injuries of limbs aggravates inflammation. 

 Inflammation relieved by half doze of physic ; cooling diet, and weak 



antiseptic solution allowed continuously to trickle over a calico band- 

 age lightly laid over the joint. Continuous irrigation with cold water. 

 When the wound is unlikely to close quickly, or simple treatment has 



failed, apply synovial styptics or a blister, with view of closing 



opening, limiting motion, and relieving pain. 

 Anchylosis apt to result where injury has been serious or case neglected 



or badly treated. 

 OPHTHALMIA. 



(a) Simple inflammation of the mucous membrane of the eye or conjunc- 



tivitis ; occurring in all animals. 



(b) Periodic or Specific ; Specific inflammation of most structures of 



the eyes of horses ; hereditary ; liable to recur, and eventually 

 causing cataract, blindness, and atrophy of the eyeball. 

 Remove any foreign body. Douche eye with warm solution boracic 



acid, 2 per cent. 

 Fomentation with tepid water containing aqueous solution of opium 



abates irritation ; four per cent, solution cocaine ; half dose physic. 

 Antiseptics, solution protargol, 2 per cent., mild astringents; vaseline 



to prevent lids sticking together. 

 Eserine and atropine, locally and alternately, diminish irritation and 



prevent adhesion of iris to lens. 

 Protect the eyes from light. 

 Periodic form relieved by cathartics, febrifuges, anodynes, belladonna 



or atropine, locally and internally.
