    摘要： The present invention contemplates an infant eye model for wide field retinal imaging by implementing nominal physical parameters and optical characteristics found in scientific literature and by simulating retinal features and details found in real eye images. The present invention also contemplates implementing a corneal model with a translucent plastic to mimic image haze and 1st Purkinje reflection. The present invention also contemplates implementing a birefringent layer to the lens posterior surface to simulate 4th Purkinje reflection and its brightness variation. The present invention further contemplates implementing a photo-realistic retinal hemisphere shell to provide retinal details and demonstrate retinopathy associated with retinal diseases.

    摘要： A gonioscopic attachment can attach to a gonioscope and can include atraumatic retention elements that are configured to engage an eye to retain the gonioscope relative to the eye. The gonioscopic attachment can be configured to position the gonioscope so that at least a portion of the concave distal surface of the gonioscopic optical element is spaced apart from the eye, and/or so that the curvature of the distal surface is angularly offset from the curvature of the eye. The gonioscope can include a fixation point configured to be visible to the subject when the gonioscope is positioned on the eye. In some embodiments, the retention elements can be incorporated directly into the gonioscope. A coupling mechanism can couple the gonioscope to a lid speculum. The gonioscope can include a light pipe, which can be configured to directly light into the eye.

    摘要： Certain embodiments provide a method of generating a color-corrected ophthalmic image. The method comprises obtaining an ophthalmic image of an eye with a nuclear sclerotic cataract or a tinted intraocular lens (“IOL”). The method further comprises determining color-shift information associated with the ophthalmic image based on at least one of user input and by processing the obtained image, the color-shift information indicative of the extent to which color in the obtained image is to be corrected to at least partially remedy the effect of the nuclear sclerotic cataract or the tinted IOL on the color of the obtained image. The method further comprises color-correcting the ophthalmic image based on the color-shift information. The method further comprises generating the color-corrected ophthalmic image based on the color-correcting.

    摘要： An OCT device includes an OCT optical system, a controller which acquires OCT data based on a signal from the OCT optical system and controls the OCT optical system to execute an OCT data acquisition operation, a light guide optical system, and an adjuster adjusting a three-dimensional position of the light guide optical system with respect to a subject eye. The light guide optical system includes an optical scanner scanning the subject eye with the measurement light, and an objective optical system which is disposed between the optical scanner and the subject eye and forms a pivot point around which the measurement light passing through the optical scanner is pivoted. The controller guides the three-dimensional position such that the pivot point is arranged at a target position set between the subject eye and the objective optical system, and further executes the OCT data acquisition operation at the target position.
