A portable, lightweight digital imaging device uses a slit scanning arrangement (30) to obtain an image of the eye, in particular the retina. Th e scanning arrangement reduces the amount of target area (32) illuminated at a time, thereby reducing the amount of unwanted light scatter and providing a higher contrast image. A detection arrangement (38) receives the light remitted from the retinal plane and produces an image. The device is operabl e under battery power and ambient light conditions, such as outdoor or room lighting. The device is noncontact and does not require that the pupil of th e eye be dilated with drops. The device can be used by personnel who do not ha ve specialized training in the eye, such as emergency personnel, pediatricians, or general practitioners. Images can be viewed in the device or transmitted to a remote location via (44). The device can also be used to provide images of the anterior segment of the eye or other small structures.
