Ocular disease in FeLV-positive cats: 11 cases (1981-1986)

Abstract

Summary A total of 147 cats positive for FeLV were retrospectively studied to determine the incidence of ocular disease. Of those cats, 97 had clinical cases of the disease and 50 were artificially infected with the virus. The incidence of ocular disease among FeLV-positive cats with clinical signs of disease was less than 2%, and represented less than 0.1% of the total feline cases for the 5-year period studied. The only ocular findings that could be associated with FeLV were pupillary and motility abnormalities. Retinal hemorrhage and subsequent degeneration found in experimentally infected and naturally infected cats were secondary to profound anemia, which was secondary to FeLV infection. On the basis of the literature and our findings, FeLV is not a major cause of primary or secondary ocular disease in the cat. Anterior uveal disease (iris bombé) was detected in 1 of 147 FeLV-positive cats, and the incidence of secondary infectious disease was zero.
