DEGENERAÇÃO DE RETINA EM FELINOS CAUSADA PELO USO DE ENROFLOXACINO

REVISÃO DE LITERATURA

Abstract

For the majority of the animals, one of the most important organs in the body is the eye. Because it is an extension of the brain, its role is to capture the light stimulation from the environment, pass on this information to the brain so it can be interpreted and then it becomes vision. The retina has its origin from the outpouching from the cerebral tissue and it is the main consciousness way from the external environment. In veterinary medicine, enrofloxacin is a fluoroquinolone antibiotic commonly used and it is administered on treatments that include skin infections and soft tissue, lower urinary tract infection in dogs and cats, Chlamydophila felis infections in cats and ulcerative colitis in dogs caused by Escherichia coli. There are restrictions in the dosage use for cats, since these animals have received doses as 20mg/Kg and they have developed retinal degeneration. Using enrofloxacin has been causing acute retinal degeneration followed by blindness of feline. The animals which developed acute retinal degeneration can present mydriasis and blindness. There is no treatment for retinal degeneration and for this reason, the prognosis becomes bad and the diagnosis is obtained from the clinical signs, acute blindness occurrence and recent use of enrofloxacin. Electroretinography is the definitive examination.
