Measurement of intraocular pressure in pig's eyes using a new tonometer prototype

We have developed a new tonometer prototype that may prove useful for noninvasive self-tonometry. The device measures the IOP by recording the force required to deform the cornea as function of distance. The goal of this experiment was to measure the IOP on porcine eyes with the new tonometer prototype. The IOP was a measured directly from the cornea of porcine's eyes with different IOPS. These preliminary data demonstrate the clinical potential of home self-tonometry. Intraocular pressure (IOP) monitoring has revealed that diurnal fluctuations in IOP are a significant independent risk for glaucoma progression. The development of a noninvasive self-tonometer and a clinical method for its use by the patient at home will help in the management of glaucoma progression.
