title: Metastatic ocular squamous cell carcinoma in a cat.
abstract: Bilateral ocular metastatic squamous cell carcinoma was diagnosed in a cat. Ophthalmic signs included bilaterally swollen optic discs, choroidal pallor, and retinal vascular engorgement. A retinal detachment was apparent in the left eye and retinal edema and hemorrhage in the right eye. Systemic signs of progressive visual impairment, ataxia, and weakness were noted. The patient's condition continued to deteriorate despite therapy with systemic antibiotics and corticosteroids, and euthanasia was performed. The diagnosis was made upon histologic examination that revealed metastasis of malignant squamous cells to both globes, the brain, and lungs.
