In what situation would a sonographer utilize a dynamic scan of the eye?

A dynamic scan of the eye is particularly useful for assessing mobility and potential retinal detachment. This technique allows the sonographer to observe the retina's movement in real time, which can help identify any separation from the underlying retinal pigment epithelium and assess the overall functionality of the retinal structure. The dynamic nature of the scan means that it can evaluate how the retina behaves under certain conditions, which is crucial in detecting abnormalities such as tears or detachment that may not be apparent in static scans.

The other options, while important in ophthalmic ultrasound, require different scanning techniques or approaches. For instance, evaluating corneal curvature, measuring intraocular pressure, and visualizing the anterior segment anatomy typically rely on static or specialized imaging methods rather than the dynamic assessment provided by a dynamic scan. Each of these parameters has specific examination techniques that may not utilize the dynamic scanning capability of ultrasound, rendering option B as the most appropriate choice for the context given.
