What imaging study is most appropriate for confirming a ruptured globe?

The most appropriate imaging study for confirming a ruptured globe is an ultrasound of the eye. This choice is favored due to the ultrasound's ability to provide real-time, high-resolution images of the ocular structures, allowing for the detection of any breaks in the globe, signs of hemorrhage, and other associated injuries.

Ultrasound is particularly effective in emergency settings, as it can be performed rapidly at the bedside without the need for patient transport, which is crucial when dealing with ocular emergencies. The assessment can be done without risking further trauma to the eye, which can occur with other imaging methods that may require physical manipulation.

In contrast, while a CT scan of the head may show some associated findings with a ruptured globe, it is often less sensitive to subtle details of the eye itself and involves exposure to radiation. An X-ray of the orbit is not typically used for this purpose, as it does not provide sufficient detail about the soft tissues of the eye. An MRI of the brain, although helpful for assessing soft tissue structures, is not suitable for evaluating acute eye injuries due to the potential for complications and the longer time required for the procedure.

Overall, ultrasound stands out as the most practical and effective method for quickly confirming a ruptured globe in
