Abstract
Ciliary body neoplasms are uncommon and have been described infrequently in the dog. We report successful treatment of three cases of canine ciliary body tumors that were diagnosed histologically as adenoma, adenocarcinoma, and malignant melanoma, respectively. They were presented with typical clinical signs that include glaucoma, anterior segment inflammation, and vision loss. On orbital ultrasound. very echodense masses involved in the ciliary body structure were revealed. Iridocyclectorny and enucleation were performed in lieu of attempts at orbital biopsy.
