Glaucoma is an age-related disease and the second most common cause of blindness in the world. The risk of developing glaucoma surges when inta-ocular pressure (IOP) increases; measurement of IOP is the cornerstone of diagnosis and management of glaucoma because elevated pressure is the singular risk factor that can be modified through surgery. Goldmann Applanation Tonometry (GAT) is considered the gold standard for measuring IOP, however GAT provides a one-point value that is unable to capture the natural circadian rhythm and sporadic surges of IOP. Consequently, traditional IOP measurement misses vital information about daily changes and spikes, and is unable to demonstrate the effect of medication or patient compliance to a given therapy.Millions of people are in need of a device to measure daily IOP data, similar to the use of glucose meters in diabetes. This capability is only possible with an off-the-counter, hand-held, not-sticking device that patients of any literacy and fair dexterity can self-administer anywhere. The device must be easy-to-use, inexpensive, not require sterilization or topical anesthesia, and must be able to connect the patients to their caregivers via virtual methods.
