Abstract

Partial or complete nasolacrimal drainage system (NLDS) occlusion is a common clinical concern in rabbits. It can be assumed that computed tomographic-dacryocystography (CTDCG) might be an efficient technique in this indication. In this prospective study, the technique of CT-DCG and the appearance of the NLDS in eight healthy rabbits on CT-DCG images are described. The quality of visualization of bony structures adjacent to the NLDS was good on pre-contrast computed tomographic images. The bony lacrimal canal had a smooth contour, a regular diameter, and its mean dimensions are provided. CT-DCG technique was easy to perform and offered a good visualization of the NLDS including anatomical narrowings and bendings. CT-DCG is a minimally invasive and informative technique for evaluating the NLDS in rabbits. Its diagnostic usefulness in exploring nasolacrimal diseases remains to be specified in this species.
