    Abstract:
    OBJECTIVE: To describe clinical and histopathologic pre-operative diagnoses as well as associated post-operative complications following orbital silicone implantation in dogs undergoing enucleation and evaluate owner satisfaction. ANIMALS STUDIED: One hundred and eighty-six dogs who underwent enucleation with orbital implant. PROCEDURES: Medical records from dogs that underwent enucleation with orbital implant performed at Virginia-Maryland Veterinary Teaching Hospital between 2007 and 2019 were reviewed. Owners were surveyed via telephone regarding client satisfaction. RESULTS: Enucleation followed by orbital implant placement occurred in 215 eyes of 186 dogs. The most common pre-operative diagnoses were glaucoma (68.8%), uveitis (17.7%), cataracts (15.8%), intraocular neoplasia (13.0%), and lens luxation (10.7%). The most common histopathologic diagnoses were retinal degeneration (46.5%), uveitis (39.5%), cataract (29.8%), retinal detachment (27.4%), and secondary glaucoma (26.5%). Fourteen eyes (6.5%) from ten dogs had post-operative complications reported including orbit cellulitis (n = 11), implant migration (n = 1), and implant extrusion (n = 1). Five of these dogs (50%) had concurrent diabetes mellitus. Median complication time from surgery was 41 days (range: 11-541 days). Ninety-five owner survey responses were completed with a median time of 6.3 years following surgery. Most owners, 85.3% (n = 81), were satisfied with the post-operative outcome. CONCLUSION: Enucleation with implantation of an orbital implant is a viable and safe method for irreversibly blind eyes. Diabetes mellitus may be a risk factor for the development of post-operative complications. Intraocular neoplasia was not associated with development of post-operative complications. Results of this study indicated high owner satisfaction rates for improving cosmetic appearance after enucleation in dogs.
