摘要： A method is disclosed for quantifying the extent a cataract impairs vision in an eye having a pupil, an ocular lens, and a retina. The method includes illuminating a localized region of the retina such that light is reflected from the localized region and is transmitted through the ocular lens. A portion of the reflected light is scattered by the cataract associated with the ocular lens. Light reflected from the localized region of the retina is collected, and the amount of scatter is measured so as to quantify the extent the scatter impairs vision of the eye.

摘要： A pupil function analyzer has three major subsystem; an electro-optical system, an electronic interface system and a computer/software system. The electro-optical system can, in turn, be described in terms of three subsystems; one that delivers controlled lights to the patient's eyes, another that forms images of the two pupils on a video camera, and a third that moves the optics to maintain alignment with the patient's eyes. The electronic interface system converts signals from the video camera into digital signals to be read by the computer and also responds to the computer to move motors for the maintenance of optical alignment and also operates the light stimuli. The computer/software saves and analyzes the signals sent by the electronic interface, controls the alignment motors, and provides an operator interface, so that the operator can select tests and examine the results.

摘要： An improved method for finding the refractive properties of lenses includes placement of the test lens in an optical system such that its image lies in a plane at which light passes through at least two spaced areas. The beams passing through those areas fall on respectively associated targets. The amount and angle of separation and the positions of the points of impingement of the beams are used to find the magnitude of spherical lens power component and magnitude, and angle of any prismatic and cylindrical power components. That information can be found by computation or by the use of means for displacing the targets and light source until the beams strike reference points on the targets. The amount of target or source displacement is then a function of the magnitude of the several optical powers and the orientation of the prismatic and cylindrical powers.An apparatus for practicing the method is described. It accomplishes target and source displacement with servo-mechanisms.

摘要： An ocular fundus imager automatically aligns fundus illuminating rays to enter the pupil and to prevent corneal reflections from obscuring the fundus image produced. Focusing the produced fundus image is automatically performed and is based upon the fundus image itself. A head restraint for the patient undergoing examination is in the form of a pair of spectacles which is not only easy to use accurately but significantly reduces the gross alignment between the optical system and the patient's pupil.

摘要： A perimetry system uses pupillary light response to a small bright light spot or other suitable stimulus which moves at a constant speed in generally a circular path centered on a fixation mark upon which the patient's field of view is fixed. The pattern traced by the spot may be a spiral, starting at the periphery and shrinking toward the fixation mark. A measuring system continuously monitors pupil size and if the retinal image of the moving light spot moves across a region of reduced sensitivity, this event is signaled by a change in pupil size.
