VOLUME STEREO TEST FIXED VECTOGRAPH
A three-dimensional grid is used as a quick and quantitative test for assessing a patient’s Stereo Volume capacity
The numbered circles present stereopsis values, measured in seconds of arc (sec), which are either Base-out (+) or Base-In (-) with increasing depth in the columns reading from left to right
If read left to right the depth increases from column A at 38 sec stair stepped up to column G at 1,875 sec. Read in reverse G-A the depth would be in decreasing steps.
Can administered alone or can be projected using an overhead projector
