Evaluate the polymethylmethacrylate (PMMA) in the form of spheres, provided with interconnecting channels, such as orbital implants in rabbits. Six New Zealand rabbits underwent enucleation of the left eye, with subsequent implantation of a 12mm diameter PMMA spheres fitted with interconnecting channels. Clinical evaluation was performed daily during the first 15 days after surgery and every 15 days until the end of the study period (45 days). For histopathological analysis three animals per experimental period were submitted to exenteration at 15 and 45 days after implantation. There was no wound dehiscence, signs of infection or implant extrusion in any animal throughout the study period. On macroscopic examination, there were several outbreaks of tissue invasion into the implant, forming beams. This type of implant allows migration of fibrovascular tissue, providing more support and no complications.
