Intraconal contrast orbitograms were obtained, using a nonionic water-soluble contrast agent, on 15 normal dogs to evaluate the technique and to define the basal orbitogram. Thirty-three intraconal orbitograms were prepared, utilizing three different injection techniques. In 21 of the intraconal orbitograms, the orbital cone was well outlined with contrast or with the optic nerve visible (or both). These were judged to be of satisfactory diagnostic quality. In the 12 other studies, the presence of most of the contrast material outside the orbital cone resulted in failure to identify the intraconal structures. These were, therefore, classified as nondiagnostic. The contrast agent used provided an adequate density and persisted in the orbital cone long enough for radiograms to be obtained. Serious complications did not appear during the study. Intraconal orbitography provides a safe method for evaluating the orbital cone.
使用非离子型水溶性造影剂，对15只正常犬进行眶锥内造影眼眶X线摄片，以评估该技术并确定基础眼眶X线摄片。利用三种不同的注射技术制备了33张眶锥内眼眶X线摄片。在21张眶锥内眼眶X线摄片中，眼眶圆锥被造影剂清晰勾勒出轮廓或可见视神经（或两者皆有）。这些被判定为具有令人满意的诊断质量。在其他12项研究中，大部分造影剂位于眼眶圆锥外，导致无法识别眶锥内结构。因此，这些被归类为非诊断性。所使用的造影剂提供了足够的密度，并在眼眶圆锥内持续足够长的时间以获得X线片。研究期间未出现严重并发症。眶锥内眼眶造影术为评估眼眶圆锥提供了一种安全的方法。
