Objective To evaluate motility of silicone orbital implants and corneoscleral prostheses, with and without use of a motility coupling post (MCP) in dogs. Animals studied Eighteen mixed‐breed dogs. Procedures The motility of an orbital silicone implant and corneoscleral prosthesis after enucleation ( n = 6), evisceration ( n = 6), or use of a MCP with evisceration ( n = 6) in dogs were compared. One eye from each dog had surgery whereas the opposite eye was used as a control. Clinical evaluations were performed three times a week. Histopathology of the orbital tissues was performed 8 and 12 weeks after surgery. Results Implant motility in dogs with evisceration (vertical movement [VM] 8.04 ± 2.13; horizontal movement [HM] 11 ± 3.05) and evisceration with MCP (VM 9.61 ± 1.59); HM was significantly greater than the enucleation group (VM 0.51 ± 0.5; HM 1.22 ± 0.68) ( P < 0.01). Prosthetic motility in dogs with evisceration with MCP was significantly greater than in dogs with evisceration; dogs with evisceration had significantly greater motility than dogs with enucleation ( P < 0.01). No postoperative complications were observed in any of the groups. No significant abnormalities were noted on histopathology. Conclusions MCP placement in silicone orbital implants significantly enhanced the prosthetic motility in dogs. This study supports the use of MCP in silicone orbital implants to enhance corneoscleral prosthesis motility and cosmetics in dogs.
