Abstract

The present invention relates to a novel instrument for the examination of an eye, namely the retina. The instrument features a LCD display for projection of various types of patterns and stimuli via an optical system onto the retina. The retina can be visualized by live IR image sequences as well as by visible light still frame images. It combines five examination types within one instrument, namely a perimetry examination, a microperimetry examination, a fixation stability examination, a scotoma boundary detection and psychophysical examinations.
