DIGITAL EYE CAMERA

摘要

A digital camera that combines the functions of the retinal camera and corneal camera into one, single small, easy to use instrument. The single camera can acquire digital images of a retinal region (9) of an eye, and digital images of a corneal region of the eye. The camera includes a first combination of optical elements for making the corneal digital images. A portion of these elements are shared elements including a first objective element (12) of an objective lens combination, a digital image sensor (18) and at least one eyepiece for viewing either the retina or the cornea. The retinal combination also includes a first changeable element of the objective lens system for focusing, in combination with the first objective element, portions or all of the retinal region at or approximately at a common image plane. The retinal combination also includes a retinal illuminating light source (27), an aperture within the frame and positioned within the first combination to form an effective retinal aperture located at or approximately at the lens of the eye defining an effective retinal aperture position, an infrared camera (34) for determining eye position, and an aperture adjustment for adjusting the effective retinal aperture based on position signals from said infrared camera. The cornea combination of elements includes a second changeable element of the objective lens system for focusing, in combination with the first objective element, portions of all or the cornea region at or approximately at a common image plane.
