Plain-English summary
A 7-year-old dog with an eye tumor underwent surgery to have an intraocular silicone prosthesis implanted to replace the affected eye tissue. While the procedure was successful for some, two dogs experienced tumor regrowth around the prosthesis and required further surgery to remove the eye. One dog is doing well three years later without any signs of tumor regrowth, but a cat that also had the procedure developed signs of cancer spreading and was euthanized four years later. This suggests that while the prosthesis can be an option for eye tumors, careful monitoring is essential.

Abstract
OBJECTIVE: To determine the outcome of implantation of an intraocular silicone prosthesis (ISP) in the eyes of dogs and cats with intraocular neoplasia. DESIGN: Retrospective case series. ANIMALS: Eight dogs and 1 cat with histologically confirmed intraocular neoplasia. PROCEDURE: Signalment, clinical signs before and after surgery, results of microscopic examination of eviscerated intraocular tissues, follow-up information, and necropsy findings, if available, were recorded for each animal. RESULTS: Five dogs and 1 cat had primary intraocular neoplasms. Two of the dogs developed regrowth of the neoplasm around the ISP 6 to 24 months after implantation, and the eyes were enucleated. The cat developed signs compatible with systemic metastasis 4 years after surgery and was euthanatized. Three dogs had multicentric or metastatic neoplasia involving the eye. Two of these dogs were euthanatized because of their systemic disease 1.5 to 7 months after ISP implantation. The third dog is alive without evidence of regrowth 3 years after surgery. CLINICAL IMPLICATION: Intraocular neoplasia is not an absolute contraindication to ISP implantation.
