Abstract
An indirect ophthalmoscope is equipped with a camera (14) to enable the view seen by the user of the ophthalmoscope to be displayed. Light is reflected into the camera by a reflector such as a prism (16) which is preferably substantially co-planar with the ophthalmoscope's optical elements (through which the user sees an eye under examination). The prism (16) and camera (14) are centrally mounted on the ophthalmoscope through mounting means, such as a frame, which has adjustment means for adjusting the positions of the prism and camera relative to the ophthalmoscope so as to alter the position of the field of view of the camera relative to the ophthalmoscope's optical elements. The adjustment means help to ensure that the field of view of the camera, and hence the displayed image, corresponds to the view seen by the user of the ophthalmoscope. The camera, prism and frame may form part of an attachment which may be retrofitted to an existing ophthalmoscope.
