About

A database (Snapfish) has been generated at Sensimed compiling all data acquired up to now on healthy volunteers and patients with glaucoma. However, healthy subjects were much younger than glaucoma patients. Additionally, the number of glaucoma patients in Snapfish database was almost twice higher than the number of healthy subjects. As it is generally accepted that intra ocular pressure (IOP) in the aging population is higher than IOP in young adults it is of interest to evaluate the 24-hour IOP pattern of older healthy subjects. Furthermore, improving our knowledge of the "healthy" 24-hour IOP pattern in comparison to glaucoma profiles would be beneficial for management of glaucoma.

Description:
Portable device that monitors the 24-hour IOP pattern by a wireless contact lens sensor (CLS) placed on the eye that sends its signals via an antenna around the orbital cavity to a recorder. Upon completion, the recording can be transmitted to a computer for read-out and visualization.
