Symptoms and prevention methods of bovine eyeball inflammation
Clinical symptoms


The eyeballs are swollen, with viscous or purulent secretions, and the upper eyelids sometimes droop without opening or half-opening. If the eyeball is protruding too much, the eyelid cannot cover the eyeball. Cavities can be seen in the cornea or sclera, the edges are often irregular, and the contents are protruding, sick animals are disturbed, appetite decreases, and sometimes the body temperature rises slightly.


  Prevention


Pay attention to management to prevent foreign bodies from stabbing the eyeball. Once the disease occurs, treat it immediately to prevent serious damage and necrosis to the internal structure of the eyeball, and prevent microorganisms from invading the brain and endangering life. If the treatment fails to achieve rapid results, eyeball enucleation should be performed immediately to ensure life safety.


1. Rinse the eyeball with 0.1% ravenul solution to remove pus: inject iodoform cod liver oil or iodoform (both 1:10). If inflammation cannot be controlled, eyeball enucleation is performed.


2. Eyeball enucleation


(1) Lying in Baoding, 100-300 ml of chloral hydrate alcohol, 500 ml of 10% glucose, and general anesthesia by intravenous injection. If the sick animal's temperament is violent and rebellious, add 100 ml of 25% magnesium sulfate.


(2) Rinse with 0.1% Revernul solution, wipe the eyeballs, and fill the cavity with sterile cotton (to prevent the eye contents from contaminating the eye sockets).


(3) Clamp the eyeball with hemostatic forceps, cut the eyeball conjunctiva with a knife above the eyeball, and separate the conjunctiva and subcutaneous tissue attached to the sclera.


(4) Use ophthalmological scissors to cut the superior rectus muscle, superior oblique muscle, inner rectus muscle, and inferior oblique muscle of outer rectus muscle, and finally cut off the eyeball retractor muscle and optic nerve, and take out the eyeball.


(5) After the eyeball is taken out, the prepared cotton gauze pattern soaked in 0.1% Revernoll is used to remove the water to form a ball and then dipped in iodoform powder (or sprinkled iodoform powder in the eye socket) into the eye socket, and then put it in the eye socket. Suture the upper and lower eyelids.


(6) Remove the sutures and take out the gauze 5-7 days after the operation.
