Plain-English summary
A 16-year-old male horse, a Connemara cross, had a swelling near the tear duct by his right eye. The veterinarian took a sample and found it was a cyst, which is a fluid-filled sac. They used a special scan to confirm this and then surgically removed the cyst. After the surgery, the horse showed no signs of the problem for seven months, and tests confirmed it was indeed a cyst related to the tear duct. Overall, the surgery worked well, and the horse recovered completely.
Abstract
To describe the differential diagnoses, investigation, and management of a periocular swelling close to the nasolacrimal duct in a horse that was consistent with a nasolacrimal duct dacryops (lacrimal cyst). A 16-year-old gelding, Connemara cross presented with a history of a periocular swelling rostroventral medial to the right eye that had been sampled by the referring veterinary surgeon. A cystic lesion was diagnosed following standing computed tomography. Surgical removal of the cystic lesion was performed, and the tissue was submitted for histopathologic and immunohistochemical examination. Surgical removal of the cyst was curative, and there was no recurrence of clinical signs 7 months later. There was a small amount of mineralized material in the center of the cyst. Histopathologic and immunohistochemical examination confirmed a nasolacrimal duct cyst. Dacryops can form in horses as well as other species and appears to have a favorable outcome if surgically removed.
