    Abstract:
    To prevent cosmetically undesirable orbital concavity after enucleation, methyl methacrylate spheres were implanted into the orbits of 73 dogs and 5 cats. In all cases, follow-up reports were obtained until suture removal 2 weeks after surgery, and for 58 animals (79%) until 6 months after surgery. Information was available for 46 animals (60%) 1 year after surgery, 28 animals (36%) 2 years after surgery, and 7 animals (9%) 3 years after surgery. Implants failed in 3 dogs and 2 cats. Complications were not detected in the remaining 73 animals (93%), and owners were pleased with the cosmetic results. The causes of implant failure in dogs varied; however, in cats, fluid accumulation was the consistent complication associated with failure. Orbital implantation of methyl methacrylate spheres was found to be a safe, practical, and inexpensive method of improving the cosmetic appearance of dogs requiring enucleation. Although the number of cats evaluated was limited, the accumulation of orbital fluid in a high percentage of those suggested that orbital implants may be less successful in this species.
