Plain-English summary
A group of 50 dogs showing signs of eye problems related to the area behind the eyeball (retrobulbar disease) underwent ultrasound exams to find out what was wrong. Most of these dogs had abnormal findings, with many showing signs of tumors or infections. Specifically, tumors were often found on the lower or inner side of the eye socket, and a significant number of dogs had issues like salivary mucoceles or abscesses. The ultrasound helped vets identify the type of problem, which is crucial for deciding on the right treatment.
Abstract
Records of 50 dogs with signs of retrobulbar disease that had ultrasonography and diagnosis based on results of cytopathology or histopathology were reviewed retrospectively. Abnormalities were identified ultrasonographically in 43 (86%) dogs. Mass effect was identified in 42% of dogs with neoplasia and 30% of dogs with abscess. Ten of 11 (91%) orbital bone lesions were in dogs with retrobulbar neoplasia. A cavitary lesion was recognized ultrasonographically in 75% of dogs with salivary mucocele and 50% of dogs with retrobulbar abscess. Neoplasms occurred predominantly on the ventral or medial aspect of the orbit, or both, which reflects invasion by nasal or sinus neoplasms. Presence of orbital bone lesions or a mass on the medial aspect of the orbit suggests neoplasia; however, other ultrasonographic signs were nonspecific.
