Study: Smart contact lens offers continuous monitoring of glaucoma progression
Researchers from Columbia University Medical Center have found that smart contact lenses that emit patterns of electrical signals can be used to detect the rate of glaucoma. The smart contact lens system, known as Triggerfish, is from Swiss startup Sensimed and is designed as a diagnostic. It offers an automated, continuous recording of ocular dimensional changes when worn over a 24-hour period.
In addition to the lens itself, Triggerfish includes an adhesive antenna, which is worn around the eye during that period and transmits the data through a cable from the antenna to a portable recorder that's worn around the patient's neck. Data is transferred via Bluetooth from the recorder to software installed on a healthcare provider's computer. This latest data on this lens system was published online today in the journal Ophthalmology.
"What we see in these measurements is a signature that indicates which glaucoma patients will get worse and which are relatively stable, which you can't do with a one-time eye pressure measurement," said study author Dr. C. Gustavo De Moraes, an associate professor of ophthalmology at Columbia University Medical Center. "This could be very useful if you want to know whether a new medication is working for a patient. You can see how their eye is reacting to the therapy in a much more meaningful way."
