Plain-English summary
In a study, veterinarians used a special imaging technique called computed tomography-dacryocystography (CT-DCG) to look at the tear drainage system in four animals: three dogs and one horse. These animals were brought in because they had ongoing issues like excessive tearing, swelling in their faces, or injuries to their faces. The researchers explained how to perform this imaging technique and noted that it is helpful because it gives a clearer view of the tear drainage system, which can be quite narrow and complex in many pets. This method can be particularly useful for diagnosing problems in the nasolacrimal system.
Abstract
Computed tomography-dacryocystography (CT-DCG) was used to evaluate the nasolacrimal system in four patients (three dogs and one horse) that were admitted for evaluation of chronic epiphora, facial swelling, or facial trauma. The four patients are reviewed and the technique for performing CT-DCG is described. Additionally, the indications for this procedure are discussed. CT-DCG is advantageous because cross-sectional imaging provides superior resolution of the nasolacrimal apparatus and the relatively long, small-diameter, bony nasolacrimal canal in most veterinary patients.
