Abstract: A stimulus is configured to treat astigmatism with changes in retinal thickness, independently of, or in combination with, treatment for myopia. In some embodiments, a stimulus pattern is arranged with respect to an astigmatic axis of the eye to decrease ocular growth in relation to the astigmatic axis. In some embodiments, the apparatus is configured to direct light to regions of retina outside the macula in relation to the astigmatic axis of the eye. In some embodiments, the intensity is modulated to provide the effect. A lens, such as a contact lens or spectacle lens may be configured with a plurality of light sources, such as projection units having a light source and focusing optics that work together to project anteriorly or posteriorly defocused images onto the retina at locations eccentric to the fovea.

Abstract: Improved optical coherence tomography systems and methods to measure thickness of the retina are presented. The systems may be compact, handheld, provide in-home monitoring, allow the patient to measure himself or herself, and be robust enough to be dropped while still measuring the retina reliably.

Abstract: An OCT system for measuring a retina as part of an eye health monitoring and diagnosis system. The OCT system includes an OCT interferometer, where the interferometer comprises a light source or measurement beam and a scanner for moving the beam on the retina of a patient's eye, and a processor configured to execute instructions to cause the scanner to move the measurement beam on the retina in a scan pattern. The scan pattern is a continuous pattern that includes a plurality of lobes. The measurement beam may be caused to move on the retina by the motion of a mirror that intercepts and redirects the measurement beam. The mirror position may be altered by the application of a drive signal to one or more actuators that respond to the drive signal by rotating the mirror about an axis or axes.

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.
