Intraocular silicone prosthesis implantation in eyes of dogs and a cat with intraocular neoplasia: nine cases (1983-1994)

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 Implications— Intraocular neoplasia is not an absolute contraindication to isp implantation
