Methyl methacrylate, acrylic resine for odontologic use, was used to fill the orbital cavity of three dogs which presented retrobulbar, eyeball and eyelid neoplasias extended to the orbital space, respectively. The material was moulded in the orbit before polymerization, while still in its paste phase. In each case, follow-up reports were obtained in the 10th and 40th days and in 18 months after surgery. Complications were not observed and improvement of cosmetic appearance was obtained.
