Using Smartphones to Detect Glaucoma

Scientists are always looking to help prevent Glaucoma and are constantly looking for ways to monitor patients’ IOP accurately for extended periods.

Now, researchers from the University of Birmingham have announced the successful detection of increasing IOP values with soundwaves emitted by a smartphone as a way of detecting early warning signs that a patient may be at risk of glaucoma using a model simulating an average human eye.

The researchers discovered a connection between the internal pressure of an object and its acoustic reflection coefficient. With additional research into eye geometry and how this influences the interaction with soundwaves, it may be possible to use a smartphone to accurately measure IOP from the comfort of the user’s home.
