[Intraocular metastasis of bronchial carcinoma in a cat]. / Intraokuläre Metastase eines Bronchialkarzinoms bei einer Katze.

A rare case of a ten-year-old neutered male Persian cat is described, in which metastasis of a pulmonary adenocarcinoma into the choroid of the right eye had led to visual impairment and major ophthalmoscopically detectable changes of the fundus. These were a generalized hyporeflectivity of the tapetal fundus due to retinal edema with multiple areas of retinal detachment and also severe edema of the papilla, furthermore an increased tortuosity and congestion of the retinal vessels. While the diagnosis of a primary lung tumor could be made intra vitam based on the result of an x-ray examination, the neoplastic nature of the fundic lesions could only be confirmed by histopathologic examination.
