Over the following 10\u2009months, the eye developed panuveitis and progressive exophthalmos with deviation of the globe and subconjunctival infiltrate mimicking severe chemosis in addition to chronic nonulcerative keratitis. B\u2010mode ultrasound of the orbit revealed a hypoechoic structure surrounding the posterior aspect of the globe on all sides, resulting in compression of the posterior sclera. Due to the chronic inflammatory changes and the vision loss, enucleation and orbital exploration were performed. Histopathology revealed periocular masses composed of clear spaces often lined by a single layer of flattened, polygonal to elongated cells, consistent with a final diagnosis of orbital and periocular SiO cellulitis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This is the first known report of orbital SiO migration in a veterinary species following retinal reattachment surgery.
