Optic Neuritis/Retinitis/Lymphosarcoma (10 year old DLH)

This cat was presented with a unilateral anterior uveitis with focal swelling of the iris. The photograph of the same eye shows a loss of detail of the optic disc due to severe cellular infiltrates (black arrows). The entire retina, especially around the optic disc, is edematous and detached. Intraretinal hemorrhage is also present. Feline leukemia virus was positive on serology. Histopathology on the globe demonstrated lymphosarcoma of the choroid, ciliary body and iris.
