Abstract

We describe the basic principles behind the design of a zoom ophthalmoscope. The purpose of such a device is to replace two instruments which are currently used to examine the retina; the small field but high magnification direct ophthalmoscope and the large field but low magnification indirect ophthalmoscope. The desired field-of-view and zoom ratio cover the fields-of-view and magnifications of these two instruments.
