Abstract

An instrument based on laser interferometry to measure fundus pulsations on the eye is presented. The eye is illuminated with a laser beam, which is reflected partially at the cornea and partially at the retina. The resulting interferences include information of the distance changes between cornea and retina. In contrast with existing techniques laser interferometry is a noncontact method and more convenient for the patient. Pulse amplitudes of normal subjects are presented and compared to results in different stages of diabetic retinopathy.
