    Abstract: The present invention is directed to an indirect ophthalmoscopic system for imaging of the ocular fundus including a headband configured to hold a digital imaging device and a plus eyepiece lens in front of an eye of the examiner, with the plus eyepiece lens positioned in between the digital imaging device and the examiner's eye, such that the examiner is focused upon the display of the digital imaging device. The aperture of the digital imaging device receives light reflected from the ocular fundus of the patient's eye, emanating from the patient's pupil. The examiner examines the patient and composes the image of the ocular fundus directly in the display screen. In this way, what the examiner sees is captured by the digital imaging device. Stereoscopic imagery is obtained by optical means that create side-by-side virtual images of the aperture of the digital imaging device within the pupil of the eye.

  • Patent number: 10213099
    Abstract: A method for measuring the geometric parameters of the eye. These measurements, known by the term biometrics, are particularly significant for the calculation of intraocular lenses after previous refractive cornea surgery. OCT images and other images are recorded simultaneously, the intensity of the reflected light generated during the OCT image recordings being lower by a factor of 2, by a factor of 10 or by a factor of 100, than the intensity of the illumination light of the other image recordings. The solution provides a method for producing other image recordings, in addition to OCT recordings, in the form of representations of the sclera or of the fundus, or keratometric, topographic or biometric measurements, or even short image sequences, for instance, while aligning the device with the eye.

The disease may also be detected with a non-transitory computer storage media having instructions stored thereon which, when executed, execute the method for detecting a disease by analysis of retinal vasculature. The method may track changes in lumen thickness, plaque, size, area and density of the disease by analysis of retinal vasculature over a predetermined period of time.

  • Patent number: 10022269
    Abstract: Patterned laser treatment of the retina is provided. A visible alignment pattern having at least two separated spots is projected onto the retina. By triggering a laser subsystem, doses of laser energy are automatically provided to at least two treatment locations coincident with the alignment spots. All of the doses of laser energy may be delivered in less than about 1 second, which is a typical eye fixation time. A scanner can be used to sequentially move an alignment beam from spot to spot on the retina and to move a treatment laser beam from location to location on the retina.

  • Patent number: 10004641
    Abstract: An ophthalmic instrument for the application of laser radiation in a patient's eye, particularly for the examination and/or surgical laser treatment of the cornea and the lens of the eye, includes a femtosecond laser, an objective and optical assemblies. The optical assemblies are arranged in front of the objective, and selectively vary the focus position in the coordinate direction X,Y and Z either within the region of the cornea or within the region of the lens of the eye. The objective or at least one lens group is movable relative to the eye. The variation of the position of the lens group objective shifts the focus position from the cornea to the lens of the eye and vice versa.

  • Patent number: 9924860
    Abstract: Geographic atrophy of the eye can be detected and measured by imaging the eye at a depth greater than the retinal pigment epithelium (RPE) at a plurality of locations of the eye, for example, using optical coherence tomography (OCT); determining a ratio of the intensities of imaging signals of a retinal layer(s) with respect to the intensity of imaging signals of a sub-RPE layer(s) at each location; determining representative values based at least in part on the determined ratios; generating a map of the representative values; and identifying diseased areas from the map. Contours and binary maps may be generated based on the identified diseased areas. The size and shape of the identified areas may be analyzed and monitored over a period of time.
