In ultrasound biometry, the speed of sound in different mediums can significantly influence the measurements and assessments made during ocular examinations. The assertion that sound travels at the same speed in both aqueous fluid and vitreous gel arises from the fact that both of these substances are primarily composed of water, which has a similar density and elasticity.

Sound waves travel through mediums based on their physical properties, particularly density and elasticity; since aqueous humor and vitreous humor have comparable compositions, the propagation speeds of sound in these two environments are quite similar. This similarity is crucial in biometry, as accurate measurements rely on understanding how sound interacts with various ocular structures.

Thus, the correct understanding of sound propagation in these two ocular mediums is essential for effectively using ultrasound in clinical settings, ensuring precision in diagnostic and measurement processes.
