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.

D008768	Methylmethacrylates	The methyl esters of methacrylic acid that polymerize easily and are used as tissue cements, dental materials, and absorbent for biological substances.
D009915	Orbit	Bony cavity that holds the eyeball and its associated tissues and appendages.	Eye Socket,Eye Sockets,Orbits,Socket, Eye,Sockets, Eye
D011474	Prosthesis Design	The plan and delineation of prostheses in general or a specific prosthesis.	Design, Prosthesis,Designs, Prosthesis,Prosthesis Designs
D002415	Cats	The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.

D004285	Dogs	The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE. They are worldwide in distribution and live in association with people. (Walker's Mammals of the World, 5th ed, p1065)	Canis familiaris,Dog
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D019736	Prostheses and Implants	Artificial substitutes for body parts, and materials inserted into tissue for functional, cosmetic, or therapeutic purposes. Prostheses can be functional, as in the case of artificial arms and legs, or cosmetic, as in the case of an artificial eye. Implants, all surgically inserted or grafted into the body, tend to be used therapeutically. IMPLANTS, EXPERIMENTAL is available for those used experimentally.
