Glaucoma Blindness Could Be Deterred by Smartphones

A new study reveals that smartphones could be used to scan eyes for early warning signs of glaucoma. Scientists at the University of Bingham have successfully experimented using soundwaves and an eye model. Their findings were published in Engineering Reports.

People at risk from glaucoma are more challenging to spot than most common eye-related diseases, making them more avoidable. For example, diabetic retinopathy is associated with individuals with diabetes. Those people are constantly monitored for tiny bulges that develop in the blood vessels of the eye.

Glaucoma is associated with elevated levels of intraocular pressure (IOP). An accurate, non-invasive way of monitoring someone’s IOP would significantly increase that person’s chances of maintaining their vision. The current method to measure IOP is tonometry, where numbing drops followed by non-toxic dye are applied to the eye. This technique has problems and measurement errors associated with it. IOP is a crucial measurement of solid vision, defined as compression created by sustained regeneration of eye fluids.

Soundwaves can be used as a mobile measurement and can detect increasing values of IOP. This early detection could prompt early diagnosis and treatment. 

Dr. Khamis Essa, co-author and Director of the Advanced Manufacturing Group at the University of Birmingham, said, “With further investigation into eye geometry and how this affects the interaction and soundwaves, it is possible to use a smartphone to accurately measure IOP from the comfort of the user’s home.” 

Glaucoma is a disease of the optic nerve which is estimated to affect 79.6 million people worldwide. If left untreated, glaucoma can cause irreversible damage. In most cases, blindness can be prevented with preventative measures and treatment.
