Abstract

A fixation lamp is described that enables a rational generation of panoramic fundus pictures with the Zeiss, Oberkochen, or other fundus camera of similar field, provided the patients collaborate. An illuminated marker at infinity is perceived centrally on the one hand, and on the other hand the marker is guided along a circle of 22 degrees eccentricity by a rotatable mirror system with click stops at every clock position 1 to 12 hours. If the camera is provided with angle scales, and use is made of its horizontal and vertical excursions, another circle of pictures at 38 degrees eccentricity can be obtained. With a total of 19 pictures a field of 96 degrees diameter is thus completely covered in a regular manner (see Fig. 6). Resolution wide-angle composite pictures of this kind is as good as resolution obtained by other means.
