Ultrasound findings in horses with severe eyelid swelling, and recognition of acute dacryoadenitis: 10 cases (2004-2010).

Objective: To report the sonographic findings, treatment, and outcome of horses with severe eyelid swelling, to describe the sonographic appearance of enlarged lacrimal glands, and to describe the clinical features of acute dacryoadenitis.

Materials And Methods: Medical records of all horses with severe eyelid swelling that underwent an ultrasound evaluation of the globe and periorbital structures from 2004-2010 were examined. Cases were limited to those in which the eyelid swelling was so severe that the globe could not be visualized.

Postmortem findings were consistent with systemic calcinosis, a syndrome of calcium deposition in the tissue of organs including lungs, kidneys, muscle, and heart that has not been previously described in horses.
