Abstract :
Research suggests that fluctuations in diurnal intraocular pressure (IOP) are a significant independent risk for glaucoma progression. An effective self-tonometer and a clinical method for its use by the patient at home would help the management of glaucoma. We describe a prototype of a new tonometer that may prove useful for non-invasive self-tonometry. Preliminary data suggests that the device is locating the area of IOP by calculating the force required. to deform the cornea at a given time.
