bovine eye Flashcards
what are the two major diseases of the eye
infectious (IBK) and neoplasia (SCC)
how do you tell the difference between traumatic ulcers and infectious ulcers
traumatic ulcers are not central and co to the edge of the sclera
why do we care about pink eye
they have decreased gains and are painful
what causes IBK and how
moraxella bovis. bacti attach to the corneal cells. the bacti NEED damage to begin penetration to the eye
what are the signs of pink eye
tearing!!
scleral injection,
central ulcer, edema
how do we tell the difference between a scar and an active ulcer
there is a tear film over the scar. no excessive tears in scarred eyes
prevention of IBK
vaccines dont really work.
fly prevention, pasture management to protect eye, UV protection

carcinomas. when do they condemn a carcass
if there is extension into the lymph node or massive infection– condemn whole head
if just in the eye, condemn the head
exenteation
take all of the contents of the orbit so SCC doesnt reccur as fast
