Smartphones could be used to scan people’s eyes for early-warning signs of glaucoma, the University of Birmingham in the UK reports. A new study shows how a mobile measurement method using smartphones would help to prevent severe ocular diseases and blindness.
Some of the most common eye-related diseases are avoidable and it’s easy to identify their risk factors before onset, but it is much harder to pinpoint people at risk from glaucoma.
Glaucoma is associated with elevated levels of intraocular pressure (IOP), and an accurate, non-invasive way of monitoring an individual’s IOP over an extended period would help to significantly increase their chances of maintaining their vision.
Soundwaves used as a mobile measurement method would detect increasing values of IOP, prompting early diagnosis and treatment.
Scientists at the University of Birmingham have successfully carried out experiments using soundwaves and an eye model, publishing their findings in Engineering Reports.
The report’s co-author, Dr. Khamis Essa, Director of the Advanced Manufacturing Group at the University of Birmingham, commented: “It’s possible to use a smartphone to accurately measure IOP from the comfort of the user’s home.”
