The Fixation Targets are displayed by selecting the Fixn icon on the Primary toolbar, pressing F8 on the keyboard of selecting Fixation on the remote control handset.


The Thomson Test Chart includes a wide range of fixation targets for use during the cover test, retinoscopy, ophthalmoscopy etc.  These images can be easily  changed or additional images added.


The images are organized into 9 groups. Each group may contain an unlimited number of images.


The default groups are as follows:


Fixation targets

Clowns

Cartoons

Landscape photographs

Animal photographs

Fish photographs

Flowers photographs

Clinical images

Task images


NOTE: If a polarised monitor is being used, group 9 contains a selection of 3D images


The final group (0)  is used to display videos.  The program uses the Windows media player to display the videos so will play any format supported by the media player.  A few sample videos are included with the Thomson Test Chart and others may be added by simply saving the video file in the Group 9 sub directory

The first video in the directory (alphabetically) will play first. Subsequent videos may be selected by pressing the up down arrow keys on the remote control or keyboard.

A video may be paused, fast forwarded or reversed using the controls shown on the main test chart screen (see below).
