Why is the use of ultrasound gel important in ophthalmic ultrasound?

The importance of using ultrasound gel in ophthalmic ultrasound primarily lies in its ability to eliminate air between the transducer and the eye. Air acts as a barrier to sound waves, causing reflections and scattering that can impede the quality of the ultrasound image. By using gel, it creates a continuous medium that facilitates the transmission of sound waves from the transducer into the eye. This enhancement in sound conduction is crucial for obtaining clear and precise images, which are vital for accurate diagnosis and treatment decisions.

In the context of ophthalmic ultrasound, ensuring optimal sound transmission is essential for evaluating various eye structures, diagnosing conditions, and planning appropriate interventions. Therefore, the role of ultrasound gel as a medium that enhances sound conduction is central to the effectiveness of the imaging process.
