A profound eye examination was done on 60 FIV-and 28 FeLV-infected cat
s as well as on 14 cats with FIP. For comparison, cats lacking these v
irus infections were also examined as controls. Ophthalmologic changes
were detected in high frequency in the infected cats and in the contr
ol groups as well. Most of the lesions could be characterized as signs
of intraocular inflammation. FIV-specific lesions could not be observ
ed ophthalmologically. FeLV-specific lesions consisted in an ocular ly
mphosarcoma (3 cases), FIP-specific lesions in a generalized granuloma
tous chorioretinitis in one cat. Other signs of ocular disease, which
were previously considered characteristic for the mentioned virus infe
ctions were also observed in the noninfected control-cats.
