12.7 Fundus VarioView
Fundus VarioView is an accessory for improved fundus observation.
The default stereo angle of the device allows stereoscopic obser-
vation of the anterior eye segment with a high aperture. When
observing the posterior eye segment, the binocular field of view is
severely restricted even with a dilated pupil, or may be not seen at
all. This is especially the case when examining the fundus periphery
using a Goldmann contact lens or when observing the chamber
angle (gonioscopy). Using the Fundus VarioView the rotary knob
allows the default stereo angle to be decreased. This leads to
increased overlapping of the two observation beam paths, thereby
increasing the binocular field of view and thus enabling stereo-
scopic observation of the fundus with a significantly improved
view.
Fundus VarioView has two working positions. The following figure
shows the observation beam path at a decreased stereo angle B
compared to the standard setting A. The two positions can be
alternated between using the rotary knob.
