A slit lamp mounted eye imaging, a slit lamp integrated, a handheld, OCT integrated, or attached to a separate chinrest-joystick assembly apparatus and method for producing a wide field and/or magnified views of the posterior or the anterior segments of an eye through an undilated or dilated pupil is disclosed. The apparatus images sections and focal planes and utilizes an illumination system that uses one or more LEDs, shifting optical elements, flipping masks, and/or aperture stops where the light can be delivered into the optical system on optical axis or off axis from center of optical system and return imaging path from the eye, creating artifacts in different locations on the eye image. Image processing is employed to detect and eliminate artifacts and masks from images. The apparatus can be used in combination with an OCT, microscope and can be disposed in a hand-held housing for hand-held use. |

1. A method for producing an image of a posterior and an anterior segment of an eye in combination with an image producing apparatus, comprising the steps of:
entering patient demographics; beginning image or movie capture; optimizing masks and illumination position to pupil size; executing autofocus, or intentional focus shift for plenoptic image; executing auto-exposure; activating sequential illumination; activating optical shift; activating mask flip; ending image or movie capture; identifying artifacts, masks and clear portions of images; identifying well focused and well illuminated portions of said images; and combining said image sections to create an artifact-free composite, plenoptic, averaged, stereo image or movie. |
