Abstract
An ophthalmoscope has viewing optics through which, in use, the user views an eye under examination. Those optics include one or more light receiving elements (,and,). The ophthalmoscope also has a centrally positioned camera (,) for detecting an image corresponding to that seen by the user. Light is reflected into the camera objective by means of a reflector (,) which is also centrally positioned on the ophthalmoscope and is situated in substantially the same plane as said elements of the viewing optics, but is laterally spaced therefrom. The central positioning of the camera does not adversely affect the lateral weight distribution of the ophthalmoscope, whilst the provision of a reflector at the same level as the optical elements helps to preserve the congruents between the image detected by the camera and that seen by the user if the condenser lens (used to form the virtual image of the eye under examination) is moved towards or away from the ophthalmoscope.
