Microsensor Monitors Eye Pressure

JAMA. 2016;315(15):1555. doi:10.1001/jama.2016.3600

A soft, disposable contact lens with an embedded microsensor received approval to help clinicians determine the best time of day to measure patients’ intraocular pressure (IOP).

Elevated IOP can indicate optic nerve damage that may signal glaucoma. But it’s a dynamic indicator that may wax and wane during the day and night or differ in sitting or supine body positions. Therefore, standard tonometry methods used to measure IOP during an eye examination may not capture the most accurate information.
