Feeling the Pressure
Feeling the Pressure
Accurate measurement of Intraocular Pressure, or IOP (the fluid pressure inside the eye) is important for the diagnosis and treatment of human eye diseases, such as glaucoma.
Currently, IOP is clinically determined with an external tonometer which measures the deflection of the cornea in response to either direct physical contact or a puff of air. Obviously these methods do not lend themselves to continual monitoring of IOP. However, it is desirable to perform continual monitoring on patients with elevated pressure, as the IOP can change significantly over time due to daily activities.
