Remote optical monitoring of intraocular pressure variations

תיאור הפרויקט ותכולתו:

Glaucoma is the second most common cause of irreversible blindness worldwide and the most common cause in Asia. The disease is characterized by increased intraocular pressure (IOP) that may eventually cause to irreparable damage to the optic nerves, resulting in permanent loss of vision.

In our project we will enable high-precision, noncontact remote and repeatable monitoring of intraocular pressure (IOP)-based on an innovative measurement principle.Using only a camera and a laser source, the device measures IOP by tracking the secondary speckle pattern trajectories produced by the reflection of an illuminating laser beam from the iris or the sclera.
