Scan people's eyes for early-warning signs of glaucoma blindness using smartphones
Some of the more common eye disorders are preventable and have clear risk factors prior to onset, but identifying a group of people at risk for glaucoma is far more difficult. Soundwaves may be used as a mobile measurement tool to detect rising IOP levels, allowing for early detection and treatment. Scientists at the University of Birmingham have published their results in Engineering Reports after successfully conducting experiments with soundwaves and an eye model.
A complete eye check is the only way to validate the reading, which is not possible in a mobile situation. Furthermore, most households cannot afford to buy the equipment for long-term home surveillance. Ocular hypertension is caused by an imbalance in aqueous fluid development and drainage, which is most common in the elderly.
Glaucoma risk rises with age, raising the probability of developing the disease. Glaucoma is an optic nerve condition that affects an estimated 79.6 million people worldwide and can cause permanent damage if left untreated. The majority of the time, blindness can be avoided with proper control and care.
