Riding the Acoustic Waves

Glaucoma specialists are constantly looking for ways to accurately and noninvasively monitor patients’ IOP for extended periods. Now, researchers from the UK’s University of Birmingham have announced the successful detection of increasing IOP values with soundwaves emitted by a smartphone, using a model simulating an average human eye (1). Khamis Essa, study coauthor and Director of the Advanced Manufacturing Group at the University of Birmingham, explained that the team “discovered a relationship between the internal pressure of an object and its acoustic reflection coefficient. With further investigation into eye geometry and how this affects the interaction with soundwaves, it [could be] possible to use a smartphone to accurately measure IOP from the comfort of the user’s home (2).”

About the Author

Aleksandra Jones

Editor of The Ophthalmologist

Having edited several technical publications over the last decade, I crossed paths with quite a few of Texere's current team members, and I only ever heard them sing the company's praises. When an opportunity arose to join Texere, I jumped at the chance! With a background in literature, I love the company's ethos of producing genuinely engaging content, and the fact that it is so well received by our readers makes it even more rewarding.
