INTRAOCULAR PRESSURE TRACKING THROUGH THE EYELID

THE GOAL IS TO DEVELOP AN INSTRUMENT FOR SAFE, QUICK, ANESTHESIA-FREE MEASUREMENT OF INTRAOCULAR PRESSURE THROUGH THE LOWER EYELID. PRESSURE IS INDICATED BY RESONANT PROPERTIES OF THE EYEBALL. A LOW-FREQUENCY EXCITER VIBRATESTHE EYELID, VIBRATIONAL ENERGY FLOW FROM THE EXCITER IS MEASURED, AND ELICITED EYEBALL RESPONSES ARE MEASURED BY ULTRASOUND. DATA ANALYSIS SPANNING FREQUENCY AND PRESSURE VARIATIONS YIELDS A RELIABLE ESTIMATE OF INTRAOCULAR PRESSURE AND ITS TIME VARIATIONS. THE PROJECT'S OBJECTIVES ARE TO DEMONSTRATE AN INSTRUMENT ON A MECHANICAL EYEBALL ANALOG, OBTAIN ACCURACY DATA, DETERMINE REQUIRED EYE EXPOSURE TO LOW-FREQUENCY VIBRATIONS AND ULTRASOUND ENERGY, AND EVALUATE THE SAFETY OF THE DEVICE.
