Which two scans are most commonly used in ocular ultrasound?

The most commonly used scans in ocular ultrasound are longitudinal and transverse scans. The longitudinal scan provides important information about the eye’s axial length and allows for visualization of structures along the visual axis. This is particularly valuable in assessing conditions such as cataracts or other abnormalities within the eye. The transverse scan, on the other hand, is crucial for examining the eye's anatomy in a cross-sectional view, which helps in evaluating various pathologies, including tumors or detachment.

The combination of these two scan orientations offers a comprehensive view of the ocular structures, enabling more accurate diagnosis and treatment planning. While other scan types may be used in certain situations, the longitudinal and transverse views are foundational to ophthalmic ultrasound practices.
